Nagios Core 4.3.4

We have several servers that have archive disks and they are usually 99% to 100% full.

The software clears the files automatically.

Currently we use a check_disk command and it is always critical. we tried to change the application to only use 90 % of the disk but have not had any success.

Is there a check disk that will just check to make sure the disk is present? We are not concerned about how much free space is available or space used.

Thank you

Tom

What if you use check disk but set warning and critical for the path to 0%

e.g. It will always be OK, but if the drive is not present you would get this

Sorry

Using this command

$ ./check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H ale.fdu.edu -t 30 -c check_drivesize -a Warning=0 Critical=0 Drive=F:

thoughts

Whoa, you started the thread asking about check_disk

Now you are changing it to check_nrpe calling check_drivesize which is part of NSClient++?

Which is it? We need to know what you are looking at before we can help, these cannot be intermingled...

With check_drivesize and your args, you would make the command like this:

[grassi-admin@anakin plugins]$ ./check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H ale.fdu.edu -t 30 -c check_drivesize "crit=free<0M" "warn=free<0M" drive=F

I'm not sure but this could be a bug in the version of NSClient++ you are using, it appears it is setting default warn/crit values AND it is displaying all drives when you only specified drive=F

We are not the authors of NSClient++ so I cannot say for sure
You could ask here

We tested this on 2 systems, running and

Scratch that previous post, I just noticed the command I gave you is missing the -a

try this Sorry about that
