Check_snmp -d & -s

Morning all,

I'm trying to refine a few snmp checks I do.

My command looks like this;

./check_snmp -H xx.xx.xx.xx -o READyNAS-MIB::diskState.1 -C nas-drive -P 2c -v


This produces the following;

/usr/bin/snmpget -t 1 -r 5 -m ALL -v 2c [authpriv] xx.xx.xx.xx READYNAS-MIB::diskState.1
READYNAS-MIB::diskState.1 = STRING: "dead"
SNMP OK - "dead" |


Now, as you can see from above, my disk 2 is 'dead' but Nagios reports this as ok. I'm under the impression I need to use the '-s' switch to specify what is good and what is bad, based on matching a string from the output.

To me, the output above would suggest that the returning string is "dead" so to get it to report that this is actually bad I should use "-s ok"  as "ok" is the string returned on all the other disks that are working ok.

----- working disk---
/usr/bin/snmpget -t 1 -r 5 -m ALL -v 2c [authpriv] xx.xx.xx.xx READYNAS-MIB::diskState.2
READYNAS-MIB::diskState.2 = STRING: "ok"
SNMP OK - "ok" |
----- working disk---



Sadly, this doesn't work as it seems that "ok" and "dead" aren't the returning strings. Neither are 1 and 0 as stated in the readynas MIB documentation.

Anyone got any ideas??

Have I messed up the syntax??

Thanks in advance,

Tristan
