PMX

PMX is the programmatic integration library for PM2 and Keymetrics.io (v1.6.8, latest stable). It enables Node.js applications to expose custom metrics (simple values, counters, meters, histograms), triggerable remote functions, exception alerts, custom events, and network traffic monitoring to the PM2 CLI and Keymetrics dashboard. Released irregularly with minor version bumps, it supports Node.js >= 0.10. Key differentiators: deep PM2/Keymetrics integration, low-overhead metric probes, and production monitoring without external monitoring services.
