`[p2p]` Remove `PeerSendBytesTotal` metric as it is costly to track, | ||
and not that informative in debugging. ([\#3184](https://github.com/cometbft/cometbft/issues/3184)) |

# 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`). | ||
|
||
## List of available metrics | ||
|
||
The following metrics are available: | ||
