-# Cross-Compiling socktop_agent for Raspberry Pi
-
-This guide explains how to cross-compile the socktop_agent on various host systems and deploy it to a Raspberry Pi. Cross-compiling is particularly useful for older or resource-constrained Pi models where native compilation might be slow.
-
-## Cross-Compilation Host Setup
-
-Choose your host operating system:
-
-- [Debian/Ubuntu](#debianubuntu-based-systems)
-- [Arch Linux](#arch-linux-based-systems)
-- [macOS](#macos)
-- [Windows](#windows)
-
-## Debian/Ubuntu Based Systems
-
-### Prerequisites
-
-Install the cross-compilation toolchain for your target Raspberry Pi architecture:
-
-```bash
-# For 64-bit Raspberry Pi (aarch64)
-sudo apt update
-sudo apt install gcc-aarch64-linux-gnu libc6-dev-arm64-cross libdrm-dev:arm64
-
-# For 32-bit Raspberry Pi (armv7)
-sudo apt update
-sudo apt install gcc-arm-linux-gnueabihf libc6-dev-armhf-cross libdrm-dev:armhf
-```
-
-### Setup Rust Cross-Compilation Targets
-
-```bash
-# For 64-bit Raspberry Pi
-rustup target add aarch64-unknown-linux-gnu
-
-# For 32-bit Raspberry Pi
-rustup target add armv7-unknown-linux-gnueabihf
-```
-
-### Configure Cargo for Cross-Compilation
-
-Create or edit `~/.cargo/config.toml`:
-
-```toml
-[target.aarch64-unknown-linux-gnu]
-linker = "aarch64-linux-gnu-gcc"
-
-[target.armv7-unknown-linux-gnueabihf]
-linker = "arm-linux-gnueabihf-gcc"
-```
-
-## Arch Linux Based Systems
-
-### Prerequisites
-
-Install the cross-compilation toolchain using pacman and AUR:
-
-```bash
-# Install base dependencies
-sudo pacman -S base-devel
-
-# For 64-bit Raspberry Pi (aarch64)
-sudo pacman -S aarch64-linux-gnu-gcc
-# Install libdrm for aarch64 using an AUR helper (e.g., yay, paru)
-yay -S aarch64-linux-gnu-libdrm
-
-# For 32-bit Raspberry Pi (armv7)
-sudo pacman -S arm-linux-gnueabihf-gcc
-# Install libdrm for armv7 using an AUR helper
-yay -S arm-linux-gnueabihf-libdrm
-```
-
-### Setup Rust Cross-Compilation Targets
-
-```bash
-# For 64-bit Raspberry Pi
-rustup target add aarch64-unknown-linux-gnu
-
-# For 32-bit Raspberry Pi
-rustup target add armv7-unknown-linux-gnueabihf
-```
-
-### Configure Cargo for Cross-Compilation
-
-Create or edit `~/.cargo/config.toml`:
-
-```toml
-[target.aarch64-unknown-linux-gnu]
-linker = "aarch64-linux-gnu-gcc"
-
-[target.armv7-unknown-linux-gnueabihf]
-linker = "arm-linux-gnueabihf-gcc"
-```
-
-## macOS
-
-The recommended approach for cross-compiling from macOS is to use Docker:
-
-```bash
-# Install Docker
-brew install --cask docker
-
-# Pull a cross-compilation Docker image
-docker pull messense/rust-musl-cross:armv7-musleabihf  # For 32-bit Pi
-docker pull messense/rust-musl-cross:aarch64-musl      # For 64-bit Pi
-```
-
-### Using Docker for Cross-Compilation
-
-```bash
-# Navigate to your socktop project directory
-cd path/to/socktop
-
-# For 64-bit Raspberry Pi
-docker run --rm -it -v "$(pwd)":/home/rust/src messense/rust-musl-cross:aarch64-musl cargo build --release --target aarch64-unknown-linux-musl -p socktop_agent
-
-# For 32-bit Raspberry Pi
-docker run --rm -it -v "$(pwd)":/home/rust/src messense/rust-musl-cross:armv7-musleabihf cargo build --release --target armv7-unknown-linux-musleabihf -p socktop_agent
-```
-
-The compiled binaries will be available in your local target directory.
-
-## Windows
-
-The recommended approach for Windows is to use Windows Subsystem for Linux (WSL2):
-
-1. Install WSL2 with a Debian/Ubuntu distribution by following the [official Microsoft documentation](https://docs.microsoft.com/en-us/windows/wsl/install).
-
-2. Once WSL2 is set up with a Debian/Ubuntu distribution, open your WSL terminal and follow the [Debian/Ubuntu instructions](#debianubuntu-based-systems) above.
-
-## Cross-Compile the Agent
-
-After setting up your environment, build the socktop_agent for your target Raspberry Pi:
-
-```bash
-# For 64-bit Raspberry Pi
-cargo build --release --target aarch64-unknown-linux-gnu -p socktop_agent
-
-# For 32-bit Raspberry Pi
-cargo build --release --target armv7-unknown-linux-gnueabihf -p socktop_agent
-```
-
-## Transfer the Binary to Your Raspberry Pi
-
-Use SCP to transfer the compiled binary to your Raspberry Pi:
-
-```bash
-# For 64-bit Raspberry Pi
-scp target/aarch64-unknown-linux-gnu/release/socktop_agent pi@raspberry-pi-ip:~/
-
-# For 32-bit Raspberry Pi
-scp target/armv7-unknown-linux-gnueabihf/release/socktop_agent pi@raspberry-pi-ip:~/
-```
-
-Replace `raspberry-pi-ip` with your Raspberry Pi's IP address and `pi` with your username.
-
-## Install Dependencies on the Raspberry Pi
-
-SSH into your Raspberry Pi and install the required dependencies:
-
-```bash
-ssh pi@raspberry-pi-ip
-
-# For Raspberry Pi OS (Debian-based)
-sudo apt update
-sudo apt install libdrm-dev libdrm-amdgpu1
-
-# For Arch Linux ARM
-sudo pacman -Syu
-sudo pacman -S libdrm
-```
-
-## Make the Binary Executable and Install
-
-```bash
-chmod +x ~/socktop_agent
-
-# Optional: Install system-wide
-sudo install -o root -g root -m 0755 ~/socktop_agent /usr/local/bin/socktop_agent
-
-# Optional: Set up as a systemd service
-sudo install -o root -g root -m 0644 ~/socktop-agent.service /etc/systemd/system/socktop-agent.service
-sudo systemctl daemon-reload
-sudo systemctl enable --now socktop-agent
-```
-
-## Troubleshooting
-
-If you encounter issues with the cross-compiled binary:
-
-1. **Incorrect Architecture**: Ensure you've chosen the correct target for your Raspberry Pi model:
-   - For Raspberry Pi 2: use `armv7-unknown-linux-gnueabihf`
-   - For Raspberry Pi 3/4/5 in 64-bit mode: use `aarch64-unknown-linux-gnu`
-   - For Raspberry Pi 3/4/5 in 32-bit mode: use `armv7-unknown-linux-gnueabihf`
-
-2. **Dependency Issues**: Check for missing libraries:
-   ```bash
-   ldd ~/socktop_agent
-   ```
-
-3. **Run with Backtrace**: Get detailed error information:
-   ```bash
-   RUST_BACKTRACE=1 ~/socktop_agent
-   ```

-# socktop_agent (server)
-
-Lightweight on‑demand metrics WebSocket server for the socktop TUI.
-
-Highlights:
-- Collects system metrics only when requested (keeps idle CPU <1%)
-- Optional TLS (self‑signed cert auto‑generated & pinned by client)
-- JSON for fast metrics / disks; protobuf (optionally gzipped) for processes
-- Accurate per‑process CPU% on Linux via /proc jiffies delta
-- Optional GPU & temperature metrics (disable via env vars)
-- Simple token auth (?token=...) support
-
-Run (no TLS):
-```
-cargo install socktop_agent
-socktop_agent --port 3000
-```
-Enable TLS:
-```
-SOCKTOP_ENABLE_SSL=1 socktop_agent --port 8443
-# cert/key stored under $XDG_DATA_HOME/socktop_agent/tls
-```
-Environment toggles:
-- SOCKTOP_AGENT_GPU=0      (disable GPU collection)
-- SOCKTOP_AGENT_TEMP=0     (disable temperature)
-- SOCKTOP_TOKEN=secret     (require token param from client)
-- SOCKTOP_AGENT_METRICS_TTL_MS=250 (cache fast metrics window)
-- SOCKTOP_AGENT_PROCESSES_TTL_MS=1000
-- SOCKTOP_AGENT_DISKS_TTL_MS=1000
-
-*NOTE ON ENV vars*
-
-Generally these have been added for debugging purposes. you do not need to configure them, default values are tuned and GPU will deisable itself after the first poll if not available.

-## WebSocket API Integration Guide
-
-The socktop_agent exposes a WebSocket API that can be directly integrated with your own applications. This allows you to build custom monitoring dashboards or analysis tools using the agent's metrics.
-
-### WebSocket Endpoint
-
-```
-ws://HOST:PORT/ws         # Without TLS
-wss://HOST:PORT/ws        # With TLS
-```
-
-With authentication token (if configured):
-```
-ws://HOST:PORT/ws?token=YOUR_TOKEN
-wss://HOST:PORT/ws?token=YOUR_TOKEN
-```
-
-### Communication Protocol
-
-All communication uses JSON format for requests and responses, except for the process list which uses Protocol Buffers (protobuf) format with optional gzip compression.
-
-#### Request Types
-
-Send a JSON message with a `type` field to request specific metrics:
-
-```json
-{"type": "metrics"}       // Request fast-changing metrics (CPU, memory, network)
-{"type": "disks"}         // Request disk information
-{"type": "processes"}     // Request process list (returns protobuf)
-```
-
-#### Response Formats
-
-1. **Fast Metrics** (JSON):
-
-```json
-{
-  "cpu_total": 12.4,
-  "cpu_per_core": [11.2, 15.7],
-  "mem_total": 33554432,
-  "mem_used": 18321408,
-  "swap_total": 0,
-  "swap_used": 0,
-  "hostname": "myserver",
-  "cpu_temp_c": 42.5,
-  "networks": [{"name":"eth0","received":12345678,"transmitted":87654321}],
-  "gpus": [{"name":"nvidia-0","usage":56.7,"memory_total":8589934592,"memory_used":1073741824,"temp_c":65.0}]
-}
-```
-
-2. **Disks** (JSON):
-
-```json
-[
-  {"name":"nvme0n1p2","total":512000000000,"available":320000000000},
-  {"name":"sda1","total":1000000000000,"available":750000000000}
-]
-```
-
-3. **Processes** (Protocol Buffers):
-
-Processes are returned in Protocol Buffers format, optionally gzip-compressed for large process lists. The protobuf schema is:
-
-```protobuf
-syntax = "proto3";
-
-message Process {
-  uint32 pid = 1;
-  string name = 2;
-  float cpu_usage = 3;
-  uint64 mem_bytes = 4;
-}
-
-message ProcessList {
-  uint32 process_count = 1;
-  repeated Process processes = 2;
-}
-```
-
-### Example Integration (JavaScript/Node.js)
-
-```javascript
-const WebSocket = require('ws');
-
-// Connect to the agent
-const ws = new WebSocket('ws://localhost:3000/ws');
-
-ws.on('open', function open() {
-  console.log('Connected to socktop_agent');
-  
-  // Request metrics immediately on connection
-  ws.send(JSON.stringify({type: 'metrics'}));
-  
-  // Set up regular polling
-  setInterval(() => {
-    ws.send(JSON.stringify({type: 'metrics'}));
-  }, 1000);
-  
-  // Request processes every 3 seconds
-  setInterval(() => {
-    ws.send(JSON.stringify({type: 'processes'}));
-  }, 3000);
-});
-
-ws.on('message', function incoming(data) {
-  // Check if the response is JSON or binary (protobuf)
-  try {
-    const jsonData = JSON.parse(data);
-    console.log('Received JSON data:', jsonData);
-  } catch (e) {
-    console.log('Received binary data (protobuf), length:', data.length);
-    // Process binary protobuf data with a library like protobufjs
-  }
-});
-
-ws.on('close', function close() {
-  console.log('Disconnected from socktop_agent');
-});
-```
-
-### Example Integration (Python)
-
-```python
-import json
-import asyncio
-import websockets
-
-async def monitor_system():
-    uri = "ws://localhost:3000/ws"
-    async with websockets.connect(uri) as websocket:
-        print("Connected to socktop_agent")
-        
-        # Request initial metrics
-        await websocket.send(json.dumps({"type": "metrics"}))
-        
-        # Set up regular polling
-        while True:
-            # Request metrics
-            await websocket.send(json.dumps({"type": "metrics"}))
-            
-            # Receive and process response
-            response = await websocket.recv()
-            
-            # Check if response is JSON or binary (protobuf)
-            try:
-                data = json.loads(response)
-                print(f"CPU: {data['cpu_total']}%, Memory: {data['mem_used']/data['mem_total']*100:.1f}%")
-            except json.JSONDecodeError:
-                print(f"Received binary data, length: {len(response)}")
-                # Process binary protobuf data with a library like protobuf
-            
-            # Wait before next poll
-            await asyncio.sleep(1)
-
-asyncio.run(monitor_system())
-```
-
-### Notes for Integration
-
-1. **Error Handling**: The WebSocket connection may close unexpectedly; implement reconnection logic in your client.
-
-2. **Rate Limiting**: Avoid excessive polling that could impact the system being monitored. Recommended intervals:
-   - Metrics: 500ms or slower
-   - Processes: 2000ms or slower
-   - Disks: 5000ms or slower
-
-3. **Authentication**: If the agent is configured with a token, always include it in the WebSocket URL.
-
-4. **Protocol Buffers Handling**: For processing the binary process list data, use a Protocol Buffers library for your language and the schema provided in the `proto/processes.proto` file.
-
-5. **Compression**: Process lists may be gzip-compressed. Check if the response starts with the gzip magic bytes (`0x1f, 0x8b`) and decompress if necessary.

-}
-
-message ProcessList {
-  uint32 process_count = 1;
-  repeated Process processes = 2;
-}
-```
-
-### Step-by-Step Integration Pseudocode
-
-```
-1. Establish WebSocket connection to ws://HOST:PORT/ws
-   - Add token if required: ws://HOST:PORT/ws?token=YOUR_TOKEN
-   
-2. For regular metrics updates:
-   - Send: {"type": "metrics"}
-   - Parse JSON response
-   - Extract CPU, memory, network info
-   
-3. For disk information:
-   - Send: {"type": "disks"}
-   - Parse JSON response
-   - Extract disk usage data
-   
-4. For process list:
-   - Send: {"type": "processes"}
-   - Check if response is binary
-   - If starts with 0x1f, 0x8b bytes:
-     - Decompress using gzip
-   - Parse binary data using protobuf schema
-   - Extract process information
-   
-5. Implement reconnection logic:
-   - On connection close/error
-   - Use exponential backoff
-   
-6. Respect rate limits:
-   - metrics: ≥ 500ms interval
-   - disks: ≥ 5000ms interval
-   - processes: ≥ 2000ms interval
-```
-
-### Common Implementation Patterns
-
-**Pattern 1: Periodic Polling**
-```javascript
-// Set up separate timers for different metric types
-const metricsInterval = setInterval(() => ws.send(JSON.stringify({type: 'metrics'})), 500);
-const disksInterval = setInterval(() => ws.send(JSON.stringify({type: 'disks'})), 5000);
-const processesInterval = setInterval(() => ws.send(JSON.stringify({type: 'processes'})), 2000);
-
-// Clean up on disconnect
-ws.on('close', () => {
-  clearInterval(metricsInterval);
-  clearInterval(disksInterval);
-  clearInterval(processesInterval);
-});
-```
-
-**Pattern 2: Processing Binary Protobuf Data**
-```javascript
-// Using protobufjs
-const root = protobuf.loadSync('processes.proto');
-const ProcessList = root.lookupType('ProcessList');
-
-ws.on('message', function(data) {
-  if (typeof data !== 'string') {
-    // Check for gzip compression
-    if (data[0] === 0x1f && data[1] === 0x8b) {
-      data = gunzipSync(data); // Use appropriate decompression library
-    }
-    
-    // Decode protobuf
-    const processes = ProcessList.decode(new Uint8Array(data));
-    console.log(`Total processes: ${processes.process_count}`);
-    processes.processes.forEach(p => {
-      console.log(`PID: ${p.pid}, Name: ${p.name}, CPU: ${p.cpu_usage}%`);
-    });
-  }
-});
-```
-
-**Pattern 3: Reconnection Logic**
-```javascript
-function connect() {
-  const ws = new WebSocket('ws://localhost:3000/ws');
-  
-  ws.on('open', () => {
-    console.log('Connected');
-    // Start polling
-  });
-  
-  ws.on('close', () => {
-    console.log('Connection lost, reconnecting...');
-    setTimeout(connect, 1000); // Reconnect after 1 second
-  });
-  
-  // Handle other events...
-}
-
-connect();
-```

-# socktop_connector
-
-A WebSocket connector library for communicating with socktop agents.
-
-## Overview
-
-`socktop_connector` provides a high-level, type-safe interface for connecting to socktop agents over WebSocket connections. It handles connection management, TLS certificate pinning, compression, and protocol buffer decoding automatically.
-
-The library is designed for professional use with structured error handling that allows you to pattern match on specific error types, making it easy to implement robust error recovery and monitoring strategies.
-
-## Features
-
-- **WebSocket Communication**: Support for both `ws://` and `wss://` connections
-- **TLS Security**: Certificate pinning for secure connections with self-signed certificates
-- **Hostname Verification**: Configurable hostname verification for TLS connections
-- **Type Safety**: Strongly typed requests and responses
-- **Automatic Compression**: Handles gzip compression/decompression transparently
-- **Protocol Buffer Support**: Decodes binary process data automatically
-- **Error Handling**: Comprehensive error handling with structured error types for pattern matching
-
-## Connection Types
-
-### Non-TLS Connections (`ws://`)
-Use `connect_to_socktop_agent()` for unencrypted WebSocket connections. 
-
-### TLS Connections (`wss://`) 
-Use `connect_to_socktop_agent_with_tls()` for encrypted connections with certificate pinning. You can control hostname verification with the `verify_hostname` parameter.
-
-## Quick Start
-
-Add this to your `Cargo.toml`:
-
-```toml
-[dependencies]
-socktop_connector = "0.1.5"
-tokio = { version = "1", features = ["rt", "rt-multi-thread", "net", "time", "macros"] }
-```
-
-### Basic Usage
-
-```rust
-use socktop_connector::{connect_to_socktop_agent, AgentRequest, AgentResponse};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    // Connect to a socktop agent (non-TLS connections are always unverified)
-    let mut connector = connect_to_socktop_agent("ws://localhost:3000/ws").await?;
-    
-    // Request metrics
-    match connector.request(AgentRequest::Metrics).await? {
-        AgentResponse::Metrics(metrics) => {
-            println!("CPU: {}%, Memory: {}/{}MB", 
-                metrics.cpu_total,
-                metrics.mem_used / 1024 / 1024,
-                metrics.mem_total / 1024 / 1024
-            );
-        }
-        _ => unreachable!(),
-    }
-    
-    // Request process list
-    match connector.request(AgentRequest::Processes).await? {
-        AgentResponse::Processes(processes) => {
-            println!("Total processes: {}", processes.process_count);
-            for process in processes.top_processes.iter().take(5) {
-                println!("  {} (PID: {}) - CPU: {}%", 
-                    process.name, process.pid, process.cpu_usage);
-            }
-        }
-        _ => unreachable!(),
-    }
-    
-    Ok(())
-}
-```
-
-### Error Handling with Pattern Matching
-
-Take advantage of structured error types for robust error handling:
-
-```rust
-use socktop_connector::{connect_to_socktop_agent, ConnectorError, AgentRequest};
-
-#[tokio::main]
-async fn main() {
-    // Handle connection errors specifically
-    let mut connector = match connect_to_socktop_agent("ws://localhost:3000/ws").await {
-        Ok(conn) => conn,
-        Err(ConnectorError::WebSocketError(e)) => {
-            eprintln!("Failed to connect to WebSocket: {}", e);
-            return;
-        }
-        Err(ConnectorError::UrlError(e)) => {
-            eprintln!("Invalid URL provided: {}", e);
-            return;
-        }
-        Err(e) => {
-            eprintln!("Connection failed: {}", e);
-            return;
-        }
-    };
-    
-    // Handle request errors specifically  
-    match connector.request(AgentRequest::Metrics).await {
-        Ok(response) => println!("Success: {:?}", response),
-        Err(ConnectorError::JsonError(e)) => {
-            eprintln!("Failed to parse server response: {}", e);
-        }
-        Err(ConnectorError::WebSocketError(e)) => {
-            eprintln!("Communication error: {}", e);
-        }
-        Err(e) => eprintln!("Request failed: {}", e),
-    }
-}
-```
-
-### TLS with Certificate Pinning
-
-```rust
-use socktop_connector::{connect_to_socktop_agent_with_tls, AgentRequest};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    // Connect with TLS certificate pinning and hostname verification
-    let mut connector = connect_to_socktop_agent_with_tls(
-        "wss://remote-host:8443/ws",
-        "/path/to/cert.pem",
-        false  // Enable hostname verification
-    ).await?;
-    
-    let response = connector.request(AgentRequest::Disks).await?;
-    println!("Got disk info: {:?}", response);
-    
-    Ok(())
-}
-```
-
-### Advanced Configuration
-
-```rust
-use socktop_connector::{ConnectorConfig, SocktopConnector, AgentRequest};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    // Create a custom configuration
-    let config = ConnectorConfig::new("wss://remote-host:8443/ws")
-        .with_tls_ca("/path/to/cert.pem")
-        .with_hostname_verification(false);
-    
-    // Create and connect
-    let mut connector = SocktopConnector::new(config);
-    connector.connect().await?;
-    
-    // Make requests
-    let response = connector.request(AgentRequest::Metrics).await?;
-    
-    // Clean disconnect
-    connector.disconnect().await?;
-    
-    Ok(())
-}
-```
-
-### WebSocket Protocol Configuration
-
-For version compatibility (if applies), you can configure WebSocket protocol version and sub-protocols:
-
-```rust
-use socktop_connector::{ConnectorConfig, SocktopConnector, connect_to_socktop_agent_with_config};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    // Method 1: Using the convenience function
-    let connector = connect_to_socktop_agent_with_config(
-        "ws://localhost:3000/ws",
-        Some(vec!["socktop".to_string(), "v1".to_string()]), // Sub-protocols
-        Some("13".to_string()), // WebSocket version (13 is standard)
-    ).await?;
-    
-    // Method 2: Using ConnectorConfig builder
-    let config = ConnectorConfig::new("ws://localhost:3000/ws")
-        .with_protocols(vec!["socktop".to_string()])
-        .with_version("13");
-    
-    let mut connector = SocktopConnector::new(config);
-    connector.connect().await?;
-    
-    Ok(())
-}
-```
-
-**Note:** WebSocket version 13 is the current standard and is used by default. The sub-protocols feature is useful for protocol negotiation with servers that support multiple protocols.
-
-## Continuous Updates
-
-The socktop agent provides real-time system metrics. Each request returns the current snapshot, but you can implement continuous monitoring by making requests in a loop:
-
-```rust
-use socktop_connector::{connect_to_socktop_agent, AgentRequest, AgentResponse, ConnectorError};
-use tokio::time::{sleep, Duration};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    let mut connector = connect_to_socktop_agent("ws://localhost:3000/ws").await?;
-    
-    // Monitor system metrics every 2 seconds
-    loop {
-        match connector.request(AgentRequest::Metrics).await {
-            Ok(AgentResponse::Metrics(metrics)) => {
-                // Calculate total network activity across all interfaces
-                let total_rx: u64 = metrics.networks.iter().map(|n| n.received).sum();
-                let total_tx: u64 = metrics.networks.iter().map(|n| n.transmitted).sum();
-                
-                println!("CPU: {:.1}%, Memory: {:.1}%, Network: ↓{} ↑{}", 
-                    metrics.cpu_total,
-                    (metrics.mem_used as f64 / metrics.mem_total as f64) * 100.0,
-                    format_bytes(total_rx),
-                    format_bytes(total_tx)
-                );
-            }
-            Err(e) => {
-                eprintln!("Error getting metrics: {}", e);
-                
-                // You can pattern match on specific error types for different handling
-                match e {
-                    socktop_connector::ConnectorError::WebSocketError(_) => {
-                        eprintln!("Connection lost, attempting to reconnect...");
-                        // Implement reconnection logic here
-                        break;
-                    }
-                    socktop_connector::ConnectorError::JsonError(_) => {
-                        eprintln!("Data parsing error, continuing...");
-                        // Continue with next iteration for transient parsing errors
-                    }
-                    _ => {
-                        eprintln!("Other error, stopping monitoring");
-                        break;
-                    }
-                }
-            }
-            _ => unreachable!(),
-        }
-        
-        sleep(Duration::from_secs(2)).await;
-    }
-    
-    Ok(())
-}
-
-fn format_bytes(bytes: u64) -> String {
-    const UNITS: &[&str] = &["B", "KB", "MB", "GB"];
-    let mut size = bytes as f64;
-    let mut unit_index = 0;
-    
-    while size >= 1024.0 && unit_index < UNITS.len() - 1 {
-        size /= 1024.0;
-        unit_index += 1;
-    }
-    
-    format!("{:.1}{}", size, UNITS[unit_index])
-}
-```
-
-### Understanding Data Freshness
-
-The socktop agent implements intelligent caching to avoid overwhelming the system:
-
-- **Metrics**: Cached for ~250ms by default (cheap / fast-changing data like CPU, memory)
-- **Processes**: Cached for ~1500ms by default (exppensive / moderately changing data)  
-- **Disks**: Cached for ~1000ms by default (cheap / slowly changing data)
-
-These values have been generally tuned in advance. You should not need to override them. The reason for this cache is for the use case that multiple clients are requesting data. In general a single client should never really hit a cached response since the polling rates are slower that the cache intervals. Cache intervals have been tuned based on how much work the agent has to do in the case of reloading fresh data.
-
-
-This means:
-
-1. **Multiple rapid requests** for the same data type will return cached results
-2. **Different data types** have independent cache timers
-3. **Fresh data** is automatically retrieved when cache expires
-
-```rust
-use socktop_connector::{connect_to_socktop_agent, AgentRequest, AgentResponse};
-use tokio::time::{sleep, Duration};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    let mut connector = connect_to_socktop_agent("ws://localhost:3000/ws").await?;
-    
-    // This demonstrates cache behavior
-    println!("Requesting metrics twice quickly...");
-    
-    // First request - fresh data from system
-    let start = std::time::Instant::now();
-    connector.request(AgentRequest::Metrics).await?;
-    println!("First request took: {:?}", start.elapsed());
-    
-    // Second request immediately - cached data  
-    let start = std::time::Instant::now();
-    connector.request(AgentRequest::Metrics).await?;
-    println!("Second request took: {:?}", start.elapsed()); // Much faster!
-    
-    // Wait for cache to expire, then request again
-    sleep(Duration::from_millis(300)).await;
-    let start = std::time::Instant::now();
-    connector.request(AgentRequest::Metrics).await?;
-    println!("Third request (after cache expiry): {:?}", start.elapsed());
-    
-    Ok(())
-}
-```
-
-The WebSocket connection remains open between requests, providing efficient real-time monitoring without connection overhead.
-
-## Request Types
-
-The library supports three types of requests:
-
-- `AgentRequest::Metrics` - Get current system metrics (CPU, memory, network, etc.)
-- `AgentRequest::Disks` - Get disk usage information
-- `AgentRequest::Processes` - Get running process information
-
-## Response Types
-
-Responses are automatically parsed into strongly-typed structures:
-
-- `AgentResponse::Metrics(Metrics)` - System metrics with CPU, memory, network data
-- `AgentResponse::Disks(Vec<DiskInfo>)` - List of disk usage information
-- `AgentResponse::Processes(ProcessesPayload)` - Process list with CPU and memory usage
-
-## Configuration Options
-
-The library provides flexible configuration through the `ConnectorConfig` builder:
-
-- `with_tls_ca(path)` - Enable TLS with certificate pinning
-- `with_hostname_verification(bool)` - Control hostname verification for TLS connections
-  - `true` (recommended): Verify the server hostname matches the certificate  
-  - `false`: Skip hostname verification (useful for localhost or IP-based connections)
-- `with_protocols(Vec<String>)` - Set WebSocket sub-protocols for protocol negotiation
-- `with_version(String)` - Set WebSocket protocol version (default is "13", the current standard)
-
-**Note**: Hostname verification only applies to TLS connections (`wss://`). Non-TLS connections (`ws://`) don't use certificates, so hostname verification is not applicable.
-
-## WASM Compatibility (experimental)
-
-`socktop_connector` provides **full WebSocket support** for WebAssembly (WASM) environments, including complete networking functionality with automatic compression and protobuf decoding.
-
-### Quick Setup
-
-```toml
-[dependencies]
-socktop_connector = { version = "0.1.5", default-features = false, features = ["wasm"] }
-wasm-bindgen = "0.2"
-serde = { version = "1.0", features = ["derive"] }
-serde_json = "1.0"
-```
-
-### What Works
-- ✅ Full WebSocket connectivity (`ws://` connections)
-- ✅ All request types (`Metrics`, `Disks`, `Processes`)  
-- ✅ Automatic gzip decompression for metrics and disks
-- ✅ Automatic protobuf decoding for process data
-- ✅ All types (`ConnectorConfig`, `AgentRequest`, `AgentResponse`)
-- ✅ JSON serialization/deserialization  
-- ✅ Protocol and version configuration
-
-### What Doesn't Work  
-- ❌ TLS connections (`wss://`) - use `ws://` only
-- ❌ TLS certificate handling
-
-### Basic WASM Usage
-
-```rust
-use wasm_bindgen::prelude::*;
-use socktop_connector::{ConnectorConfig, SocktopConnector, AgentRequest};
-
-#[wasm_bindgen]
-pub async fn test_connection() {
-    let config = ConnectorConfig::new("ws://localhost:3000/ws");
-    let mut connector = SocktopConnector::new(config);
-    
-    match connector.connect().await {
-        Ok(()) => {
-            // Request metrics with automatic gzip decompression
-            let response = connector.request(AgentRequest::Metrics).await.unwrap();
-            console_log!("Got metrics: {:?}", response);
-            
-            // Request processes with automatic protobuf decoding
-            let response = connector.request(AgentRequest::Processes).await.unwrap();
-            console_log!("Got processes: {:?}", response);
-        }
-        Err(e) => console_log!("Connection failed: {}", e),
-    }
-}
-```
-
-### Complete WASM Guide
-
-For detailed implementation examples, complete code samples, and a working test environment, see the **[WASM Compatibility Guide](../socktop_wasm_test/README.md)** in the `socktop_wasm_test/` directory.
-
-## Security Considerations
-
-- **Production TLS**: You can enable hostname verification (`verify_hostname: true`) for production systems, This will add an additional level of production of verifying the hostname against the certificate. Generally this is to stop a man in the middle attack, but since it will be the client who is fooled and not the server, the risk and likelyhood of this use case is rather low. Which is why this is disabled by default. 
-- **Certificate Pinning**: Use `with_tls_ca()` for self-signed certificates, the socktop agent will generate certificates on start. see main readme for more details. 
-- **Non-TLS**: Use only for development or trusted networks
-
-## Environment Variables
-
-Currently no environment variables are used. All configuration is done through the API.
-
-## Error Handling
-
-The library uses structured error types via `thiserror` for comprehensive error handling. You can pattern match on specific error types:
-
-```rust
-use socktop_connector::{connect_to_socktop_agent, ConnectorError, AgentRequest};
-
-#[tokio::main]
-async fn main() {
-    match connect_to_socktop_agent("invalid://url").await {
-        Ok(mut connector) => {
-            // Handle successful connection
-            match connector.request(AgentRequest::Metrics).await {
-                Ok(response) => println!("Got response: {:?}", response),
-                Err(ConnectorError::WebSocketError(e)) => {
-                    eprintln!("WebSocket communication failed: {}", e);
-                }
-                Err(ConnectorError::JsonError(e)) => {
-                    eprintln!("Failed to parse response: {}", e);
-                }
-                Err(e) => eprintln!("Other error: {}", e),
-            }
-        }
-        Err(ConnectorError::UrlError(e)) => {
-            eprintln!("Invalid URL: {}", e);
-        }
-        Err(ConnectorError::WebSocketError(e)) => {
-            eprintln!("Failed to connect: {}", e);
-        }
-        Err(ConnectorError::TlsError(msg)) => {
-            eprintln!("TLS error: {}", msg);
-        }
-        Err(e) => {
-            eprintln!("Connection failed: {}", e);
-        }
-    }
-}
-```
-
-### Error Types
-
-The `ConnectorError` enum provides specific variants for different error conditions:
-
-- `ConnectorError::WebSocketError` - WebSocket connection or communication errors
-- `ConnectorError::TlsError` - TLS-related errors (certificate validation, etc.)
-- `ConnectorError::UrlError` - URL parsing errors
-- `ConnectorError::JsonError` - JSON serialization/deserialization errors
-- `ConnectorError::ProtocolError` - Protocol-level errors
-- `ConnectorError::CompressionError` - Gzip compression/decompression errors
-- `ConnectorError::IoError` - I/O errors
-- `ConnectorError::Other` - Other errors with descriptive messages
-
-All errors implement `std::error::Error` so they work seamlessly with `Box<dyn std::error::Error>`, `anyhow`, and other error handling crates.
-
-### Migration from Generic Errors
-
-If you were previously using the library with generic error handling, your existing code will continue to work:
-
-```rust
-// This continues to work as before
-async fn my_function() -> Result<(), Box<dyn std::error::Error>> {
-    let mut connector = connect_to_socktop_agent("ws://localhost:3000/ws").await?;
-    let response = connector.request(AgentRequest::Metrics).await?;
-    Ok(())
-}
-
-// But now you can also use structured error handling for better control
-async fn improved_function() -> Result<(), ConnectorError> {
-    let mut connector = connect_to_socktop_agent("ws://localhost:3000/ws").await?;
-    let response = connector.request(AgentRequest::Metrics).await?;
-    Ok(())
-}
-```

-# WASM Compatibility Guide for socktop_connector
-
-This directory contains a complete WebAssembly (WASM) compatibility test and implementation guide for the `socktop_connector` library.
-
-## Overview
-
-`socktop_connector` provides **full WebSocket networking support** for WebAssembly environments. The library includes complete connectivity functionality with automatic compression and protobuf decoding, making it easy to connect to socktop agents directly from browser applications.
-
-## What Works in WASM
-
-- ✅ **Full WebSocket connections** (`ws://` connections)
-- ✅ **All request types** (`AgentRequest::Metrics`, `AgentRequest::Disks`, `AgentRequest::Processes`)
-- ✅ **Automatic data processing**: Gzip decompression for metrics/disks, protobuf decoding for processes
-- ✅ Configuration types (`ConnectorConfig`) 
-- ✅ Request/Response types (`AgentRequest`, `AgentResponse`)  
-- ✅ JSON serialization/deserialization of all types
-- ✅ Protocol and version configuration builders
-- ✅ All type-safe validation and error handling
-
-## What Doesn't Work in WASM
-
-- ❌ TLS connections (`wss://`) - use `ws://` only
-- ❌ TLS certificate handling (use non-TLS endpoints)
-
-## Quick Start - WASM Test Page
-
-```bash
-# Please note that the test assumes you have and agent runnign on your local host at port 3000. If you would like to use an alternate configuration please update lib.rs prior to build. 
-
-# Build the WASM package
-wasm-pack build --target web --out-dir pkg
-
-# Serve the test page
-basic-http-server . --addr 127.0.0.1:8000
-
-# Open http://127.0.0.1:8000 in your browser
-# Check the browser console for test results
-```
-
-<img src="./screenshot_09092025_134458.jpg" width="85%">
-
-
-## WASM Dependencies
-
-The test uses the WASM-compatible networking features:
-
-```toml
-[dependencies]
-socktop_connector = { version = "0.1.5", default-features = false, features = ["wasm"] }
-serde = { version = "1.0", features = ["derive"] }
-serde_json = "1.0"
-wasm-bindgen = "0.2"
-console_error_panic_hook = "0.1"
-
-[dependencies.web-sys]
-version = "0.3"
-features = ["console"]
-```
-
-**Key**: Use `features = ["wasm"]` to enable full WebSocket networking support in WASM builds.
-
-## Implementation Strategy
-
-### 1. Use socktop_connector Types for Configuration
-
-```rust
-use wasm_bindgen::prelude::*;
-use socktop_connector::{ConnectorConfig, AgentRequest, AgentResponse};
-
-#[wasm_bindgen]
-pub fn create_config() -> String {
-    // Use socktop_connector types for type-safe configuration
-    let config = ConnectorConfig::new("ws://localhost:3000/ws")
-        .with_protocols(vec!["socktop".to_string(), "v1".to_string()])
-        .with_version("13".to_string());
-    
-    // Return JSON for use with browser WebSocket API  
-    serde_json::to_string(&config).unwrap_or_default()
-}
-```
-
-### 2. Create Type-Safe Requests
-
-```rust
-#[wasm_bindgen]
-pub fn create_metrics_request() -> String {
-    let request = AgentRequest::Metrics;
-    serde_json::to_string(&request).unwrap_or_default()
-}
-
-#[wasm_bindgen]
-pub fn create_processes_request() -> String {
-    let request = AgentRequest::Processes;
-    serde_json::to_string(&request).unwrap_or_default()
-}
-```
-
-### 3. Parse Responses with Type Safety
-
-```rust
-#[wasm_bindgen]
-pub fn parse_metrics_response(json: &str) -> Option<String> {
-    match serde_json::from_str::<AgentResponse>(json) {
-        Ok(AgentResponse::Metrics(metrics)) => {
-            Some(format!("CPU: {}%, Memory: {}MB", 
-                metrics.cpu_total,
-                metrics.mem_used / 1024 / 1024))
-        }
-        _ => None
-    }
-}
-```
-
-### 4. Browser Integration
-
-Then in JavaScript:
-
-```javascript
-import init, { 
-    create_config, 
-    create_metrics_request, 
-    parse_metrics_response 
-} from './pkg/socktop_wasm_test.js';
-
-async function run() {
-    await init();
-    
-    // Use type-safe configuration
-    const configJson = create_config();
-    const config = JSON.parse(configJson);
-    
-    // Create WebSocket with proper protocols
-    const ws = new WebSocket(config.url, config.ws_protocols);
-    
-    ws.onopen = () => {
-        // Send type-safe requests
-        ws.send(create_metrics_request());
-    };
-    
-    ws.onmessage = (event) => {
-        // Handle responses with type safety
-        const result = parse_metrics_response(event.data);
-        if (result) {
-            console.log(result);
-        }
-    };
-}
-
-run();
-```

-# Zellij Socktop Plugin
-
-A Zellij plugin that displays real-time system metrics from a socktop agent.
-
-## Quick Start
-
-1. **Build the plugin:**
-   ```bash
-   cargo build --target wasm32-wasi --release
-   ```
-
-2. **Install in Zellij:**
-   ```bash
-   # Copy the WASM file to Zellij plugins directory
-   mkdir -p ~/.config/zellij/plugins
-   cp target/wasm32-wasi/release/zellij_socktop_plugin.wasm ~/.config/zellij/plugins/socktop.wasm
-   cp plugin.yaml ~/.config/zellij/plugins/
-   ```
-
-3. **Use in Zellij layout:**
-   ```yaml
-   # ~/.config/zellij/layouts/socktop.yaml
-   template:
-     direction: Horizontal
-     parts:
-       - direction: Vertical
-         borderless: true
-         split_size:
-           Fixed: 1
-         run:
-           plugin:
-             location: "file:~/.config/zellij/plugins/socktop.wasm"
-             configuration:
-               server_url: "ws://localhost:3000/ws"
-       - direction: Vertical
-   ```
-
-4. **Launch Zellij with the layout:**
-   ```bash
-   zellij --layout socktop
-   ```
-
-## Plugin Features
-
-- **Real-time Metrics**: Displays CPU and memory usage
-- **Auto-refresh**: Updates every 2 seconds
-- **Reconnection**: Press 'r' to reconnect to socktop agent
-- **Configurable**: Set custom server URL in plugin config
-- **Error Handling**: Shows connection status and errors
-
-## Configuration Options
-
-- `server_url`: WebSocket URL for socktop agent (default: `ws://localhost:3000/ws`)
-
-## Controls
-
-- **`r`** - Reconnect to socktop agent
-- Plugin updates automatically every 2 seconds
-
-## Development Notes
-
-This is a scaffold implementation. To make it fully functional:
-
-1. **Async Operations**: Zellij plugins have limitations with async operations. You may need to:
-   - Use a different async runtime or approach
-   - Handle WebSocket connections in a background thread
-   - Use message passing between threads
-
-2. **Error Handling**: Add more robust error handling for:
-   - Network connectivity issues
-   - Invalid server URLs
-   - Agent unavailability
-
-3. **UI Improvements**: 
-   - Add more detailed metrics display
-   - Implement scrolling for large datasets
-   - Add color coding for status indicators
-
-4. **Performance**: 
-   - Implement caching to reduce agent requests
-   - Add configurable update intervals
-   - Optimize WASM binary size
-
-## Dependencies
-
-- `zellij-tile`: Zellij plugin framework
-- `socktop_connector`: WebSocket connector with WASM support
-- `serde`: JSON serialization
-- `chrono`: Time handling (WASM-compatible)
-
-## Building
-
-```bash
-# Add WASM target
-rustup target add wasm32-wasi
-
-# Build for WASM
-cargo build --target wasm32-wasi --release
-
-# The plugin will be at: target/wasm32-wasi/release/zellij_socktop_plugin.wasm
-```
