I would like to reconfigure Nagios e-mail notification to send me information about largest files on a disk.

This is oneliner which shows me largest 20 files:

find / -type f -ls | sort -k 7 -r -n | head -20 |grep -v lastlog | awk '{ sum=$7 ; hum[1024**3]="Gb";hum[1024**2]="Mb";hum[1024]="Kb"; for (x=1024**3; x>=1024; x/=1024){ if (sum>=x) { printf "%.2f %s" " " $11 "\n",sum/x,hum[x];break;} }}'

I'd like Nagios to trigger this command on check_disk alert and to attach results in Nagios notification.

Could that be possible?

Thanks

You probably want to use check_nrpe for this and add it as a separate check and give it the one liner as the remote command to be executed. You can't alter check_disk unless you edit the source code and recompile it.

The max output for chech_nrpe is 1024 chars, so you might need to cut it down a bit.
