pipeline:
  inputs:
    - name: fluentbit_metrics
      tag: fluentbit.metrics
      scrape_interval: 10

      processors:
        metrics:
          - name: metrics_selector
            metric_name: /storage/
            action: include
          - name: metrics_selector
            metric_name: /fs/
            action: exclude

          - name: labels
            delete: name


  outputs:
    - name: stdout
      match: '*'

service:
  flush: 5
  daemon: off
  log_level: info

pipeline:
  inputs:
    - name: fluentbit_metrics
      tag: fluentbit.metrics
      scrape_interval: 10

      processors:
        metrics:
          - name: metrics_selector
            context: delete_label_value
            label: name stdout.0

          - name: labels
            delete: name


  outputs:
    - name: stdout
      match: '*'

All processors are only valid with the YAML configuration format. Processor configuration should be located under the relevant input or output plugin configuration.

Metric_Name parameter will translate the strings which is quoted with backslashes /.../ as Regular expressions. Without them, users need to specify Operation_Type whether prefix matching or substring matching. The default operation is prefix matching. For example, /chunks/ will be translated as a regular expression.
