Chris Douglas commented on HADOOP-4594:
---------------------------------------
Sorry, my previous comments were cursory and this deserves more attention. I
ran this past someone who had worked with nagios and Hadoop and it's my
understanding that- while a good base- the patch as-is is not generally
applicable. Specifically, the feedback was that the configuration contained
several hard-coded values (hostnames, ports, environment variables) and that a
combination of jps and grep was not a sufficient check of node health.
What I can speak to directly: configuration files- even templates for common
tools- are not usually checked into contrib. On the other hand: you're right,
there isn't a good place for this right now. As far as monitoring goes, there
are several efforts currently in progress (Chukwa, metrics, HADOOP-3628 (the
{{ping()}} functionality specifically)) that would be compelling points of
integration.

> I would like to create a set of local via NRPE and remote check scripts that
> can be shipped with the hadoop distribution and used to monitor Hadoop. I
> already have completed the NRPE scripts. The second set of scripts would use
> wget to read the output of the hadoop web interfaces. Do these already exist?
> I guess these would fall under a new contrib project.
