Is there a "Backplane Utilization" OID for Procurve Switches

[lgmills]

I am in the process of setting up a network monitor using a general-purpose SNMP-polling application (OpManager).

I know that many Cisco switches support a SNMP OID for backplane utilization, is there such an OID in the HP Procurve MIBs? I have switch models 5406zl, 4104gl and 4000m that will be monitored.

I have done some browsing of the HP MIB set, but I feel like it's looking for a needle in a haystack.

If anyone could point me to the right MIB and OID, it would be greatly appreciated.
