# Metrics

LagomChain nodes can enable [Cosmos SDK telemetry](https://docs.cosmos.network/main/learn/advanced/telemetry) to allow for observing and gathering insights about the LagomChain application. Under the hood, it uses the [`go-metrics`](https://github.com/hashicorp/go-metrics) package and the Prometheus client library to expose different [types of metrics](https://prometheus.io/docs/concepts/metric_types/) like gauges and counters. For best practices on how to use different metrics types, check this [blog article](https://blog.pvincent.io/2017/12/prometheus-blog-series-part-2-metric-types/).

Find below a list of supported LagomChain modules with custom metrics and telemetry. Using the metrics you can e.g. run performance profiles and display them in a [Grafana](https://grafana.com/) dashboard.
