Re: space usage monitoring problem

[Martin Pala]

This is strange - the validation code works with each service independently.

I used following configuration to test this problem (monit configuration 
file):

--8<--
...
check device rootfs path /dev/hda5
   if failed permission 660 then alert
   if failed uid root then alert
   if failed gid disk then alert
   if space usage > 10 % then alert
   if inode usage > 10 % then alert

check device vfatfs path /dev/hda6
   if failed permission 660 then alert
   if failed uid root then alert
   if failed gid disk then alert
   if space usage > 10 % then alert
   if inode usage > 10 % then alert
--8<--

Both my filesystems are uses more then 10% of space. Monit sent alerts 
correctly (monit log):


--8<--
[CEST Oct 25 21:43:07] 'vfatfs' file permission check passed [current 
permission=660]

[space usage>10%]
[CEST Oct 25 21:43:08] Resource limit matched notification is sent to

--8<--

Please try to run monit in debug mode (se you will see the above 
messages) and send us output.

Thanks,
Martin
