In Weave Cloud’s monitoring section, you will see application, cluster, host and network metrics that are automatically collected by the Prometheus instance running in your cluster and pushed to Weave Cloud.

The GUI in Weave Cloud helps you explore which metrics are available. Once you have identified metrics, you can write PromQL expressions. For example, if you have a counter metrics, you may wish to try rate(counter[5m]) to find the rate of change of the counter on a five-minute interval.

See the Prometheus documentation on PromQL for complete documentation on how to construct PromQL queries.
