Nagios Support Forum

I know this has been asked before, and quite frankly I may have been the one asking...but can't find it....

If I have a "DISK CRITICAL - free space: /ua1002 848 MB (4% inode=90%):" and a few days later another disk goes critical and say I have this: "DISK CRITICAL - free space: /ua1002 848 MB (4% inode=90%): /var 100 MB (4% inode=90%):"

is there a way to have nagios be smart enough to detect the message is different and to send out another notification? basically treat it as a new CRITICAL hard state?

Not Nagios directly but I've seen some suggestions that say you could use a wrapper script to export the critical info to a temp file. Then if the critical info in the text file changes you could send a custom notification using the command pipe.

In my opinion each critical alerts must be handled and resolved.
In our company we always trying to have Nagios as green as possible.
If you need to monitor different folder/mount points in one check - I think better not doing it.
Monitor each critical folder(s)/mount point(s) using different checks and always handle the critical - do not leave the critical for even for 1H unresolved (your situation - few days)

I tend to agree with questrad's line of thinking here. I try to never double up on checks unless it makes sense to do so, for example "If 3 of these 5 things are down then alert", but then BPI is good for that sort of thing.
