NiFi monitor garbage collection from Grafana

[#1]

Hi All,

Thanks a lot to this awesome community.

I have use case for which I need to monitor number of garbage collections in NiFi.

this linkks shows how to enable GC logging by bootstrap.conf change. Is there any way I can sent GC collection info thru REST API to Ambari Metric collector system?

Thanks a lot.

Hi @dhieru singh

AmbariReportingTask can be used to send metric to AMS. You can see the GC metrics that it can send to AMS : https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-ambari-nar/1.5.0/org.apache.n...

In the default Grafana dashboard, the information is not used. But you can create a dashboard to show jvm.gc.runs.G1 Young Generation for example. Below a simple dashboard that show this information:
