Check SNMP alerting on Status messages

I am configuring SNMP service checks for NetApp aggregate status which returns either Online or Offline. How do I configure the service so that if it returns "Offline" it will set the state to critical?
Code: Select all
[root@ ~]# snmpwalk -v2c -c public <IP> 1.3.6.1.4.1.789.1.5.11.1.5
NETAPP-MIB::aggrState.1026 = STRING: online

check_snmp allows you to perform regular expression matching which can trigger critical states if there is no match.
from check_snmp --help
-R, --eregi=REGEX
Return OK state (for that OID) if case-insensitive extended REGEX matches
This will need some testing, but I think you're after this:
Code: Select all
check_snmp -H <IP> -C public -P 2c -o 1.3.6.1.4.1.789.1.5.11.1.5 -R /online$/

Thank you. I ended up with the follow argument which worked as instructed.
Code: Select all
check_snmp -H <IP> -P 2c -c public -t 30 -o 1.3.6.1.4.1.789.1.5.11.1.5.1026 -r \online
Tested this with different regex to ensure that status not matching "online" will trigger a critical state. Thanks!
