- pulse-lets-go-agent: collects metrics from PBX nodes via ESL (FreeSWITCH) or AMI (Asterisk) - AMI client (raw TCP) for Asterisk Manager Interface - Collector interface: collect, connect, subscribe hangup events, close - FreeSWITCH collector: show channels, max_sessions, idle_cpu - Asterisk collector: CoreShowChannels, CoreSettings - System collector: /proc/loadavg, /proc/stat (CPU idle) - Failure tracker: sliding window for call_failure_rate - NATS publisher: pulse.metrics.<node_id> every 5 seconds - Graceful shutdown, retry logic (5 failures → status=down) - Template configs for UC nodes (Asterisk) and ses-sip (FreeSWITCH)
