Monitor QNAP disk space in Nagios

[imran_khan]

Hello,

I have gone through below link to monitor QNAP disk space in Nagios.

http://exchange.nagios.org/directory/Pl ... mp/details

I want to know that, how to find out “Index for OID (dskPercent)”?

Thanks,
Imran Khan.

Have you tried just specifying an int there? Like the example shows you? Such as:

Code: Select all

-i 1

Hello,

Tried 1,2,3 etc and getting same error.

[root@localhost libexec]# ./check_disk.sh -H qnap_ip -C community_name -i 1 -w 0:90 -c 0:95 -l "/dev/md0"
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UCD-SNMP-MIB::dskUsed.1

You may want to take a look at trying something similar to this:

http://www.linuxforums.org/forum/gentoo ... -snmp.html

You could also run a check_snmp against that OID, on the remote system and get the int's returned, If you're still having issues with that plugin I'd recommend trying to contact the plugin developer who's information is in the plugin script.

Considering it is looking for an snmp oid offset, let's do an snmpwalk and see what you have available.

Code: Select all

snmpwalk -v 2c -c community_name qnap_ip UCD-SNMP-MIB::dskTotal

[imran_khan]

Hello,

Ran the mentioned command, getting below error.

[root@localhost libexec]# snmpwalk -v 2c -c community qnap_ip UCD-SNMP-MIB::dskTotal
UCD-SNMP-MIB::dskTotal = No Such Object available on this agent at this OID


Thanks,
Imran Khan.

Looks like your device does not support this oid. You could either remove this section of the code from the plugin, if you do not need it, such as if the output you referenced earlier was all you were looking for, or you could find a different plugin that does not use that particular oid and not have to modify the plugin.

Hello,

Thanks for the reply.

Is there any best plugin to monitor QNAP space in nagios? I tried 2-3 plugins and did not work.

Thanks,
Imran Khan.

We do not have a suggested plugin, this is not a device we see too often. What have you tried for plugins, and what responses did the give? Have you checked with qnap about specific oids you might monitor for best results?

Hello,

I am trying check_qnap_volumes but getting below error.

http://exchange.nagios.org/directory/Pl ... us/details

[root@localhost libexec]# ./check_qnap_volumes --help

SNMP perl mouldue is already installed in the system. Please suggest me on the same.

Hello,
