Edward Capriolo commented on HADOOP-4594:
-----------------------------------------
I removed the extra text, sorry about that.
As far as I can tell, nothing in the scripts/plugins are hard coded. the SAMPLE
file is just example usage. Not part that would be installed on the nagios
server.
For example:
command_line $USER1$/check_http -H $HOSTADDRESS$ -u
http://$HOSTADDRESS$:$ARG1$/jobtracker.jsp -p $ARG1$ -r RUNNING
This check follows the standard nagios conventions in that it allows the user
to specify host and port. -r RUNNING is a specific regular expression being
searched for on the page. Since the status pages are in more of a human then
machine readable format extracting information from them is difficult, Complex
parsing of dfshealth.jsp is also subject to change.
Trying to make nagios check scripts more complete is difficult as nagios deals
with only simple states.
Critical, Warning, OK, UNKNOWN, and a plugin only can output one status line.
Let me know what you think would make the scripts better.

> 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.
