HOWTO: Monitor puppet with zabbix and do agent command testing/troubleshooting

This turned out to be really easy, but not obvious with the GUI. The GUI shows the proc.num syntax as:

proc.num[ <,user> <,state>]

but the manual has the real story:

proc.num[ <,user> <,state> <,cmdline>]

So you can use the cmdline to monitor something like this:

ruby /usr/sbin/puppetd -w 0

with:

proc.num[ruby,,,"/usr/sbin/puppetd"]

To troubleshoot agent monitoring strings, use the commandline on the box (quicker than clicking around in the GUI) like this:

zabbix_agent -t proc.num[ruby,,,"/usr/sbin/puppetd"]
