Subject Re: Adding configuration parameters and monitoring metrics for custom service
Date Wed, 20 May 2015 23:25:58 GMT
Hi Jayesh,


Enhanced dashboard is the ongoing effort and is being actively worked upon on trunk. This
feature will be available in the upcoming Ambari release 2.1.0. (Bring tracked at https://issues.apache.org/jira/browse/AMBARI-9792)


After this epic is completed, minimal effort needs to be done to expose the AMS stored metric
data via Ambari API and create your service's dashboard view in Ambari web.?


Documentation for the  feature will be done shortly.


For reference you can look at the example patch for Accumulo service (https://issues.apache.org/jira/browse/AMBARI-9910)
which is using this epic work and trying to get a new service dashboard.


-Thanks

  Jaimin

It is also stack defined through widgets.json (default). In 2.1 you can create a dashboard
view for yourself and save it / share it, etc.


Documentation for widgets.josn is still missing on wiki, should be there soon.

Sid

Thanks again - that's exactly what I was looking for!
And I think for the metrics display on the UI, I will need to browse through the Ambari web,
right?

Hi Jayesh,

Did you look through the API docs?

Thank you for the link, Sid !
I had a look at that, but it does not have any details or pointers to samples on how to dump
your own metrics to the Ambari Metrics subsystem.
For example, my sample service is TSDB - where I have several TSDB daemons running on an Ambari
cluster and I want to dump their health metrics to Ambari so that it can be displayed on the
UI. I know how to extract the TSDB metrics from TSDB - but don't know how where and how to
route that to the Ambari metrics collector (or montior?).

And once those TSDB metrics are in Ambari, how do I show them in simple graphs in Ambari?

Subject: Adding configuration parameters and monitoring metrics for custom service

The Ambari doc page https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=38571133
is very useful and I was able to add a test service.
I am at the next evolution step on some pointers for adding configuration parameters and monitoring
metrics.
And ofcourse, the step after that would be how to expose the metrics in Ambari UI and the
REST API.

I did come across https://issues.apache.org/jira/browse/AMBARI-5707 and was not sure if I
need to "understand" that in order to write and inject my own metrics.

Any pointers?

Thanks,
Jayesh
