I am trying to monitor the voice and fax calls through my routers, I have HUM and I loaded the CISCO-CALL-HISTORY-MIB. However, I cannot get any data when I create a graph or report to monitor ciscoCallHistoryCallDisconnectCause as an example.
I also could not understand the meaning of the instances going from 1267073499.170396 to 1267162828.170441.
Anybody has an idea about the meaning of the insatances and what may be the reason that I cannot extract any information from this mib.
The instance IDs in the ciscoCallHistoryTable are ciscoCallHistoryStartTime and ciscoCallHistoryIndex. ciscoCallHistoryStartTime is a TimeStamp indicating when the call started, and the ciscoCallHistoryIndex value is a unique arbitrary number to identify a specific call which had a given start time.
A TimeStamp represents the value of sysUpTime when the specific call began.
