question about alert

[Claudio Kuenzler]

Hello,

I agree that the server still has plenty of space and also inodes look OK.
So what you need to find out now is the WARNING and CRITICAL thresholds.
These thresholds determine when a warning or critical notification should
be sent by Nagios. The warning threshold is probably set very low.

As this check is a NRPE check, you have to find this information on your
host serv2 (172.19.4.192) in the nrpe.cfg file.
You have to look for the check_command[*] lines and find the check
responsible for the disk space. There you will find the warning (-w) and
critical (-c) thresholds which you can adapt and then restart the nrpe
daemon.
