> Key: NIFI-7359
> URL: https://issues.apache.org/jira/browse/NIFI-7359
> Project: Apache NiFi
> Issue Type: Bug
> Components: Configuration
> Reporter: alexandre vautier
> Priority: Major
> Fix For: 1.12.0
>
> Original Estimate: 1h
> Time Spent: 20m
> Remaining Estimate: 40m
>
> * Create a process group A
> * Add a process B inside A
> * Setup the prometheus report sink
> * Look at [http://localhost:9092|http://localhost:9092/]
> * Some metrics on the process B have the process group A as parent, other
> have the root process group.
> Look at file PrometheusMetricsUtil.java, the problem is between lines 441 and
> 462 variable parentPGId is used instead of parentId. 4 metrics are ok:
> TOTAL_BYTES_READ, TOTAL_BYTES_WRITTEN, AMOUNT_THREADS_TOTAL_ACTIVE and
> AMOUNT_THREADS_TOTAL_TERMINATED while the others 12 are wrong.
