Description

Use Case

specify a list of additional custom resources to report on from the yaml

Expected behavior

counters will be added for these custom resources

Actual behavior

This is a statically defined list in code: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/puppetagent/puppetagent.go#L56-#L78

However, additional struct items can be output. For instance, on a windows node you might want to define

Registryvalue float64 yaml:"registry_value"

These will largely be dependent on the last_run_summary.yaml of a node.

For instance the values might require some user defined configuration:

Issue type: feature
Difficulty: 2
Estimated time: 1-3 hours
Activity status: fresh
Clarity: mostly clear
Prerequisites: Go programmingTelegraf plugin development
Newbie friendliness: 50
Research direction: Modify plugins/inputs/puppetagent/puppetagent.go to add a configuration option allowing users to specify custom resource fields from last run summary.yaml. Parse the YAML for those fields and add corresponding counters. The existing static list at lines 56-78 can serve as a template.
