Matt Burgess updated NIFI-7017:
-------------------------------
Status: Patch Available (was: In Progress)
> PrometheusReportingTask does not report nested process group status
> -------------------------------------------------------------------
>
> Key: NIFI-7017
> URL: https://issues.apache.org/jira/browse/NIFI-7017
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The clear() command added in NIFI-6715 causes the registry to be reset on
> every call to createNiFiMetrics. In the case of nested process groups this
> method is a recursive call, so the registry keeps getting cleared except for
> the last visited process group.
> The clear() should only be done when createNiFiMetrics is called on the root
> process group, in order to clean up the registry before adding all the
> components' metrics.
