All four are opt-in via config file:
- FPM_STATUS_URL — PHP-FPM pool stats (active/idle workers, slow requests, max children reached, accepted conn)
- NGINX_STATUS_URL — nginx stub_status (active connections, reading/writing/waiting, accepts/handled/requests)
- SSL_DOMAINS — TLS cert expiry check per domain (days left, valid, expires_at)
- CHECK_PORTS — TCP port availability per port with known service name mapping
Also refactors loadConfigFromFile to return *Config directly instead of a positional tuple.
- cpu.iowait_percent: % of time CPU is waiting on disk I/O
- tcp: established/time_wait/close_wait/listen counts; max_time_wait
system limit included on Linux for context
- file_descriptors: used vs max (Linux reads /proc/sys/fs/file-nr,
macOS reads kern.openfiles / kern.maxfiles via sysctl)
These three metrics directly surface the most common causes of
unexplained PHP/Laravel timeouts at the system level.
- Collect CPU, memory, swap, disk, disk I/O, network (per-second rates),
load average, system info, uptime, and top processes via gopsutil
- Install script supports both Linux (systemd) and macOS (launchd)
- Auto-detect OS and architecture for binary download
- Accept TOKEN env var for non-interactive installs
- Config at /etc/pulsewise-collector/config with simple KEY=VALUE format
- Debug mode logs full response body
- Hostname auto-detected if not set in config
