Answer 1

Define the metrics name and interval in source section, define the post action in sink section.

You can write the yaml file like this:

---
sources:
    - name: meter_source
      interval: 600
      meters:
          - "disk.device.usage"
      sinks:
          - meter_sink
sinks:
    - name: meter_sink
      transformers:
      publishers:
          - notifier://

For more pipeline code logic and data processing mechanism, you shall read the code and related annotation in the source code files.
