Nagios Support Forum

I've successfully managed to interogate our Sophos XG 230 firewall to get CPU Load information using snmpwalk from the Nagios XI server CLI. However when configured and run, the service within Nagios XI produces the following error:

No valid data returned (No Such Instance currently exists at this OID)

The snmpwalk command used is:
snmpwalk -v3 -l authPriv -u <snmp-user> -a MD5 -A 'MD5Pass' -x DES -X 'DESPass' <IPAddress> 1.3.6.1.2.1.25.3.3.1.2
Returning (2 CPU Firewall): HOST-RESOURCES-MIB::hrProcessorLoad.196608 = INTEGER: 19
HOST-RESOURCES-MIB::hrProcessorLoad.196609 = INTEGER: 20

In terms of the Nagios service configuration:
check_xi_service_snmp! -p 161 -o '1.3.6.1.2.1.25.3.3.1.2' -P 3 --seclevel=authPriv --secname=<snmp-user> --authproto=MD5 --authpasswd='MD5Pass' --privpasswd='DESPass' -x des -m SFOS-FIREWALL-MIB -w 80 -c 95

Can someone point me in the right direction in terms of why I'm getting the error within Nagios XI or is there already a plugin I can use that would return the correct data from the firewall?

TIA.

Hi @rj-admin2, thanks for reaching out.

This is what the SNMP Wizard sets up.
Maybe try...

Hi,

Many thanks for the suggestions. I have now managed to get things going as I wanted. I've just to use the OID for each individual CPU and have 2 separate service checks defined.

Hi @rj-admin2,

I'm glad you got things working!

Thanks for the update.
