Instance Setting in SNMP-Based Discovery

Dashboard Server
,

Hello everybody

I’ve a custom MP created for SCOM 2007 some Years ago.

The MP is still working with SCOM 2012 R2 but I’ve found a problem with the discovery of one class property.

Not too bad, since this property is not really needed but I want to know why its not working anymore.

I’m pretty sure that this was working with SCOM 2007. I dind’t work a lot with SNMP Devices, so maybe someone can give me a hint…

 

The Discovery InstanceSetting looks like this:

          <InstanceSettings>
            <Settings>
              <Setting>
                <Name>$MPElement[Name="My.Custom.Class"]/myProperty$</Name>
                <Value>$Data/SnmpVarBinds/SnmpVarBind[OID='<OID>']/Value$</Value>
              </Setting>
            </Settings>
          </InstanceSettings>

On the Mgmt-Server I get a Warning (Event ID 31876):

Data item returned no information for parameter '$Data/SnmpVarBinds/SnmpVarBind[OID='<OID>']/Value$'
 This usually indicates that the query is incorrect.

The OID is correct, I get a Value when testing with a MIB Browser.
