Metrics
Evmos nodes can enable Cosmos SDK telemetry
to allow for observing and gathering insights about the Evmos application.
Under the hood, it uses the go-metrics package
and the Prometheus client library to expose different types of metrics
like gauges and counters.
For best practices on how to use different metrics types,
check this blog article.
Find below a list of supported Evmos modules with custom metrics and telemetry. Using the metrics you can e.g. run performance profiles and display them in a Grafana dashboard.
