# `PromEx.ManualMetricsManager`
[🔗](https://github.com/akoutmos/prom_ex/blob/master/lib/prom_ex/manual_metrics_manager.ex#L1)

This GenServer is responsible to keeping track of all the manual
metrics from your configured plugins. It will fetch metrics initially
when starting (either immediately or after a configured delay). At that
point if you would like to refresh your metrics data points call the
`refresh_metrics/1` function.

manual metrics data points.
