Custom graphs
I read a post in a different thread that talked about creating custom graphs that involved math functions to change something from bytes to kilobytes. The example they used was to create a custom graph with this in the oid field : <snmp oid>/($deltatime*1000).
My question is, where would I find rules for how to perform mathematical operations on the data that is returned from a GET operation, and is it possible to combine multipe OID's into one operation for the purpose of a custom graph? i.e. <OID1>-<OID2>/<OID3> Something to that effect?
