Agent:
Added GET /healthz that returns 200 immediately.
File: main.rs (router now includes /healthz).
CI workflow:
Start agent from target/release on both OSes.
Set SOCKTOP_ENABLE_SSL=0 explicitly.
Ubuntu: wait on curl http://127.0.0.1:3000/healthz (60s), log tail and ss/netstat on failure.
Windows: wait on Invoke-WebRequest to /healthz (60s), capture stdout/stderr, print netstat on failure.
File: .github/workflows/ci.yml.
Release highlights
Introduced split client/agent architecture with a ratatui-based TUI and a lightweight WebSocket agent.
Added adaptive (idle-aware) sampler: agent samples fast only when clients are connected; sleeps when idle.
Implemented metrics JSON caching for instant ws replies; cold-start does one-off collection.
Port configuration: --port/-p, positional PORT, or SOCKTOP_PORT env (default 3000).
Optional token auth: SOCKTOP_TOKEN on agent, ws://HOST:PORT/ws?token=VALUE in client.
Logging via tracing with RUST_LOG control.
CI workflow (fmt, clippy, build) for Linux and Windows.
Systemd unit example for always-on agent.
TUI features
CPU: overall sparkline + per-core history with trend arrows and color thresholds.
Memory/Swap gauges with humanized labels.
Disks panel with per-device usage and icons.
Network download/upload sparklines (KB/s) with peak tracking.
Top processes table (PID, name, CPU%, mem, mem%).
Header with hostname and CPU temperature indicator.
Agent changes
sysinfo 0.36.1 targeted refresh: refresh_cpu_all, refresh_memory, refresh_processes_specifics(ProcessesToUpdate::All, ProcessRefreshKind::new().with_cpu().with_memory(), true).
WebSocket handler: client counting with wake notifications, cold-start handling, proper Response returns.
Sampler uses MissedTickBehavior::Skip to avoid catch-up bursts.
Docs
README updates: running instructions, port configuration, optional token auth, platform notes, example JSON.
Added socktop-agent.service systemd unit.
Platform notes
Linux (AMD/Intel) supported; tested on AMD, targeting Intel next.
Raspberry Pi supported (availability of temps varies by model).
Windows builds/run; CPU temperature may be unavailable (shows N/A).
Known/next
Roadmap includes configurable refresh interval, TUI filtering/sorting, TLS/WSS, and export to file.
