Subject: [Nagios-users] Sending and monitoring email
Pardon the newbie question, but I need to know if Nagios will do what
I
need before investing time and effort in it.
I need to monitor an email sync management system where I send an
email
to the server and measure the time it takes to get synced to a device.
The email send is SMTP. The receive is an HTTP push to the device.
Can Nagios be set up to
- wake up every five minutes
- send an email
- start a transaction timer
- go into a passive wait for an HTTP message
- get and process the HTTP message
- stop the timer and report the time difference?
Yes, if you can code everything from 'send an email' on as a plugin in
your favorite language. Nagios must be able to perform those actions by
running an external script/program (i.e. plugin). There's no standard
plugin that does anything like that except check_email_loop.pl which
sends an e-mail, then on the next run verifies that it was received in a
POP account. You could use that as a model.
I think your only sticky-wicket is listening on port 80 for the HTTP
response but I can't say for sure not being familiar with the system
you're working with. I assume that the whole transaction takes less than
a minute or so. If it's longer, you might want to have the HTTP listener
run separately as a daemon and log to a file on receipt and on your next
run of the plugin, verify that the previous transaction was received.
If so, would you be kind enough to point me to the features of Nagios
that I would need to set up the email send and passive HTTP wait?
http://nagiosplug.sf.net - Developer Guidelines and examining how the
check_email_loop.pl plugin works would probably be a start.
