Incorrect disk usage check

Hi,

I have enabled linux snmpd monitoring on our servers and monitoring disk usage as following commands.

check_xi_service_snmp_linux_storage! -C public --v2c -m "^/usr$" -w 85 -c 95 -f

but when I go to monitored server and check disk (df -h) I found that disk usage is about 99% on "/usr" and Nagios did not send me any notification alert.

Please see attached screenshot.

Regards,
Surachai C.

Could you try using the following command on the linux command line?

Code: Select all

./check_snmp_storage.pl -H 127.0.0.1 -C public -m zzzz -w 80 -c 81 -v
Replace the -H, -m, -w, and -c values with your own.

Hi,

It means the initial commands for check disk from wizard is not correct and I have to udpate this command to all my monitored nodes, right ?.

Actually, run the following command in terminal and post the output:

Code: Select all

/usr/local/nagios/libexec/check_snmp_storage.pl -H <IP address> -C public --v2c -m "^/usr$" -w 80 -c 95 -f

Hmmm, this is showing only 58% used.

Because I already increased disk space.

Can you post the full configuration for the service, not just the command

I'm not sure which one you want and how could I get full configuration for you. Or you mean configuration files, please suggest.

Go to the Core Config Manager->Services->locate your service, click on the "Download" actions button (the diskette icon), save the file and post it, so we can review it. Thanks!
