randomize a service's check interval

[Gius, Mark]

You'll also probably want to set up freshness checking for this service, so that if the script stops sending in data, Nagios will take steps to manually scrape the info, or restart the script.

You can set up the check as a passive check in Nagios.  Run the check
from a similar looping script like you had before to do the random
timing stuff and have it send the result back to nagios either
directly using the command interface or using send_nsca and have nsca
submit the result to Nagios.

See:

http://nagios.sourceforge.net/docs/3_0/passivechecks.html

and the nsca_wrapper script is useful for such stuff.  See:

http://exchange.nagios.org/directory/Addons/Passive-Checks/NSCA-Wrapper/details



That makes a lot of sense.  Don't know why I didn't think of that.  Thank you very much!!
