Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.7.1
Reporter: amarnath reddy pappu
Description
In Grafana, NIFI-Hosts dashboard does not show any metrics though data present
in the AMS.
Steps to reproduce it
1. Install the cluster the and add NIFI service.
2. Goto NIFI and add Ambari reporting task so that it sends the metrics to AMS.
3. You can see NIFI-Home shows the Graphs but NIFI-Hosts does not.
Below API call returns the data points
http://xxx:6188/ws/v1/timeline/metrics?metricNames=jvm.uptime._avg&appId=nifi&instanceId=&startTime=1541611634&endTime=1541698034
where as with hostname clause it does not return any
http://xxx:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=jvm.uptime._avg&hostname=%&appId=nifi&instanceId=&startTime=1541611634&endTime=1541698034&topN=20&topNFunction=avg&isBottomN=false
NIFI is sending instanceid and but AMS is not handling correctly.
