Extract metrics

MediaMTX provides several metrics through a dedicated HTTP server, in a format compatible with Prometheus.

This server can be enabled by setting metrics: yes in the configuration.

Metrics can be extracted with Prometheus or with a simple HTTP request:

curl localhost:9998/metrics

Metrics can be filtered by using HTTP query parameters:

type=[TYPE]: show metrics of a certain type only (where TYPE can be paths, hls_muxers, rtsp_conns, rtsp_sessions, rtsps_conns, rtsps_sessions, rtmp_conns, rtmps_conns, srt_conns, webrtc_sessions)
path=[PATH]: show metrics belonging to a specific path only
hls_muxer=[PATH]: show metrics belonging to a specific HLS muxer only
rtsp_conn=[ID] show metrics belonging to a specific RTSP connection only
rtsp_session=[SESSION]: show metrics belonging to a specific RTSP session only
rtsps_conn=[ID] show metrics belonging to a specific RTSPS connection only
rtsps_session=[SESSION]: show metrics belonging to a specific RTSPS session only
rtmp_conn=[ID] show metrics belonging to a specific RTMP connection only
rtmps_conn=[ID] show metrics belonging to a specific RTMPS connection only
srt_conn=[ID] show metrics belonging to a specific SRT connection only
webrtc_session=[ID] show metrics belonging to a specific WebRTC session only
