I have installed Nifi (HDF alongside HDP) over HDP through Ambari.
It is showing like "No data Available" for Nifi graphs on Ambari dashboards.
I checked Nifi logs and observed that Nifi sending metrics Ambari through AmbariReportingTask.
INFO [Timer-Driven Process Thread-5] o.a.n.r.ambari.AmbariReportingTask AmbariReportingTask[id=3b90bc0f-a6c0-49db-b721-4dbc04cef28e] Successfully sent metrics to Ambari in 0 ms
I have followed the below link and succeeded in getting graphs on Grafana.
But still Ambri showing no data available for Nifi.
Can any one help me out on it.
