Re: [clo-devel] Cron job to check available disk vs nagios?

I've done a basic monitor program (RT ticket #24), checking all disk spaces every 5 minutes and send alert mails if

• there's a disk which has over 90% full, and
• no alert mail (for this disk) was sent during last check.

Sounds pretty good. May I suggest tweaking the hysteresis?

With the logic as described, I would expect to get an alert email every 10 minutes. It might be better to suppress alerts until a check sees that the condition has cleared. An extension might add a "low tide" reset mark some distance from the trigger level (e.g. <= 80%) to avoid small oscillations around the 90% mark.

A low-frequency (i.e. daily or weekly) nag also helps keep persistent issues from being forgotten.

Just trying to offer my experience if not my time.
