Composer Monitor

Composer Monitor (in older releases licensed separately as the Extended Monitoring License) delivers centralised metrics, log aggregation, alerting, and pre-built Grafana dashboards across every Composer instance in a fleet. It ships as a small Docker stack — Grafana, Loki, and Prometheus — with the Composer-specific dashboards already provisioned. From R2 2026 it is included in the base Composer licence with no separate add-on to buy or plug-in entry to activate.

It uses 25+ extended Prometheus metrics (RTMP target stats, processing usage, alarms, GPU detail, WebSocket throughput) and tags every metric and log line with System Label, Version, and Hostname so Grafana can slice across the whole fleet from a single view.

For full coverage — installation, dashboards, alerts, customisation, troubleshooting — see the dedicated Composer Monitor manual.
