Use this filter to configure the Prometheus metrics that are going to be exposed for scraping.

The purpose with the Prometheus Filter is to prevent flooding of metrics in the storage of the Prometheus host.

The filter is positive, so you define what you want to get. Except in the situation where no Prometheus Filter exists or all existing Prometheus Filters are disabled, then all available metrics are exposed for scraping. The exception being MIM metrics from batch workflows. In case of MIMs from a batch workflows no metrics will be collected unless there is a filter whitelisting them.

A prometheus filter consists of one or many metric filters. Each metric filter has a Metric Name Filter and optionally a number of Label Filter(s). A metric that passes at least one of the metric filters will be exposed for scraping.

Example of a prometheus filter with one metric filter that has no label filters.
