Hi Adam,
Doing it in the poller seems to cause horrible graph artifacts sometimes (snmp is dodgy, after all), so we prefer to store it in the database.
I wonder when they added it to the MIB. I looked at the one on cco, but it didn't have any changelog in the MIB itself.
I think you missed this part:
REVISION "200812050000Z" DESCRIPTION "Added the following High Capacity and Overflow objects in cempMemPoolTable. cempMemPoolUsedOvrflw, cempMemPoolHCUsed, cempMemPoolFreeOvrflw, cempMemPoolHCFree, cempMemPoolLargestFreeOvrflw, cempMemPoolHCLargestFree, cempMemPoolLowestFreeOvrflw, cempMemPoolHCLowestFree, cempMemPoolUsedLowWaterMarkOvrflw, cempMemPoolHCUsedLowWaterMark, cempMemPoolSharedOvrflw, cempMemPoolHCShared. Added couple of new groups cempMemPoolHCGroup and cempMemPoolOvrflwGroup. Added a new compliance cempMIBComplianceRev3 which deprecates cempMIBComplianceRev2."
Cheers :) Sander
