Warning is set to 10% and Critical is set to 0%. I could understand why this would be an issue if they both were set to 0%, but they are not. In both warning and critical alerts, according to logs, the space is returning 0 megabytes and 0%.. Even if the megabytes were increasing a little, I'm basing it on percentage, and the 0% shouldn't change.. but in this case, they both looked like they weren't changing.

This is with  check_disk (nagios-plugins 1.4.2) 1.57

after looking at the source, I would suggest putting your critical value
at 1 or 2 or 5% and see if the service still flaps between warning and
critical.
It looks like it's possible that if your disk space is changing between almost 0 and 0, then it could flap (from what I can tell) if critical is
also set to 0%.

good luck,

I setup Nagios to watch a service. I thought I had told it to notify me every 16 hours. Over the weekend, a problem occurred and I was notified
every 40 minutes or so.    I can't help but think I must be missing a
configuration somewhere.

The service in question is monitoring free space on a filesystem.   I
want it to go into warning when there is less than 10% free and become critical when there is 0% free. From the event log, it seems like the state is going from CRITICAL to WARNING to CRITICAL, and every time it
goes to CRITICAL, it sends me email.. but I can't figure out why it's
going back into warning mode when the space free remained at 0%.

Part of the event log:

[02-17-2007 23:45:43] SERVICE ALERT: menc001;mc_vol001
Space;WARNING;HARD;4;DISK WARNING - free space: /Volumes/mc_vol001 0 MB

Space;CRITICAL;notify-by-email;DISK CRITICAL - free space:
/Volumes/mc_vol001 0 MB (0%):


Relevant part of service definition:

        notification_options            u,c,r
        notification_interval           960
        notification_period             24x7
        check_command
check_nrpe!check_disk!10%!0%!/Volumes/mc_vol001
        }


Ultimately I only want it to notify me when it's critical, not in
warning, and I want the notification to only be sent every 16 hours (960 units, my unit is defined elsewhere as 60 seconds). Any help as
to what I'm doing wrong would be appreciated.  Thanks.
