- # Metrics
-
- Tendermint 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` if 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

- ## Useful queries
-
- Percentage of missing + byzantine validators:
-
- ```
- ((consensus\_byzantine\_validators\_power + consensus\_missing\_validators\_power) / consensus\_validators\_power) * 100
- ```
