Module oc_producer

Producer is a source of metrics.

This module defines the oc_producer behaviour. Required callback functions: read/2.

  • read(Registry, Callback) -> ok - called by exporters. Read should call Callback with the current values of all metrics supported by this metric provider. The metrics should be unique for each combination of name and resource.

  • cleanup(Registry) -> ok - optional. Called when producer removed from Registry
