Hi,
I wrote a nagios parser for wmflabs, it downloads instance list from
labsconsole and using simple application it parses it and generate
nagios configs, it's currently running periodicaly on
nagios.wmflabs.org and thanks to that nagios is updated when you
create a new instance, it parses the gerrit classes from nova and
define services according to that, currently it knows only apache
service, but I can of course insert more classes there. The source
code is located in trunk/tools/nparser. Thanks to Ryan Lane for the
semantic query in order to get a list.
If you would find any problem with the parser or source, feel free to fix it!
