Im trying to build an alert based on the OID 1.3.6.1.2.1.10.20.1.3.4.1.2 ISDN-MIB:isdnLapdOperStatus. It is a node custom poller.
I´ve map also the following values:
1 Inactive
2 TEI_ASSIGNED
3 MULTIPLE_FRAME_ESTABLISHED
This is the result of the poll for a specific node.
Based on that node custom poller called ISDN_Status and in addition to an additional custom poller I was able to build a Tabular Universal Device Poller widget on the web page that reflects the status of the ISDN and the interface description from the LOCIFINCRC_COUNTER_TYPE - LABEL custom interface poller.
The question is how should I build the alert so I get alerted when the status changes from 3 (MULTIPLE_FRAME_ESTABLISHED) to a value of 2 or 1? I tried different Custom Node POller, Custom Table Poller alerts with no success.
Thanks
