I have just been trying to poll the license usage via SNMP from our CPPM appliances and it took me a while to work out why it is failing. The OIDs for license usage are Traps, which makes no sense to me as they are not events which can generate a trap. License over-utilisation is a trap - an event occurs which fires a trap, but the current active licenses and licenses in use are not events. So if you can't poll them (which you can't because they are traps) then what would cause these to be sent? There's no hint in the MIB, this is the description:
A trap which indicates the ClearPass cluster license utilization details of the application.
<cppmNodeApplicationName> indicates the name of the application,
<cppmClusterLicenseTotalCount> indicates total cluster-wide
license count of the application,
<cppmClusterLicenseUsageCount> indicates the used
cluster-wide license count of the application.
It's not just licenses either - there are loads like this, such as cppmDiskSpaceRemaining (there is another trap "LowDiskSpace" which makes perfect sense), cppmImageFile, cppmServiceName, there are loads of these which are values, not events.
How can these be used?
