Ambari metrics widget (custom) for service cannot be added to service dashboard

dvielvoye — Tue, 09 Feb 2016 03:15:22 GMT

I'm running a NIFI cluster (1 NCM and 3 nodes) with ambari. I have added metrics and widget definition to it . Data are collected (present in DB) but the widget are not added to the service dashboard. When trying to add them (they are visible in the "browse widgets") nothing happens . On the service dashboard ,I cannot create any widget either.

@Daniel Hendrix

What did you use to integrate nifi with ambari ?

Official repo or a repo from github?

I suggest to wait for official version of repo.

@Daniel Vielvoye

it's not yet supported but in general you can refer to this api to add metrics https://cwiki.apache.org/confluence/display/AMBARI/Metrics+Collector+API+Specification

+ @bbende

@Daniel Hendrix couple of things to check

1. Ambari metrics service is up

2, The metrics in question are appearing in AMS. You can query AMS using phoenix.

Here is a collection of useful links on building metrics integration (including official apache page and Bryans blog on this and sample code)

on general : I follow the tuto from http://bryanbende.com/development/2015/07/31/ambari-metrics-part2-metrics-collector/ and install guidelines (http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.0.0/bk_Installing_HDP_AMB/content/index.html)

- Ambari metrics is up and working correctly to monitor systems and HDFS usage.

- I did install the repo from Horton (HDP with ambari 2.2) for Nifi I started with the repo from Ali and modified it to create the NCM node and the slaves nodes.

- I also used the AmbariReport in Nifi (I think work from Bryan in the Nifi service provided by Ali)

-I checked with phoenix :data are present in database

A quick update : I did reinstall Ambari completely and also re-check all my config files : at least now the add widget is working but still does not display data (while phoenix shows data in hbase) I suspect something with the fact that I collect data on the 3 NiFi nodes while I try to display them for the whole service ...
