Metrics

CometBFT can report and serve the Prometheus metrics, which in their turn can be consumed by Prometheus collector(s). This functionality is disabled by default. To enable the Prometheus metrics, set instrumentation.prometheus=true in your config file. Metrics will be served under /metrics on 26660 port by default. Listen address can be changed in the config file (see instrumentation.prometheus\_listen\_addr).
