# Openmetrics collector metricset
<warning>
  This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.
</warning>

This is the `collector` metricset of the Openmetrics module. It collects metrics from endpoints that follow Openmetrics format.
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
