=== Filtering metrics

In order to filter out/in metrics one can make use of `metrics_filters.include` `metrics_filters.exclude` settings:

[source,yaml]
-------------------------------------------------------------------------------------
- module: openmetrics
  metricsets: ['collector']
  period: 10s
  hosts: ["localhost:9090"]
  metrics_path: /metrics
  metrics_filters:
    include: ["node_filesystem_*"]
    exclude: ["node_filesystem_device_*", "^node_filesystem_readonly$"]
-------------------------------------------------------------------------------------

The configuration above will include only metrics that match `node_filesystem_*` pattern and do not match `node_filesystem_device_*`
and are not `node_filesystem_readonly` metric.
