SNMP Get value and SNMP Trap correlation

[mmussons]

It's possible to know when was the last time that an item was activated? I explain my problem with an example.

If I get an SNMP OID value every our and two consecutives times this value is 1 (alarm) an alarm must be displayed in the browser, but if inside this our I receive a TRAP with the same signal with 0 value, no alarm must be displayed.

So I need to create a trigger that correlate both values and only display an alarm if the last value from both items is 1 after X time, an our for example.

Thanks in advance.

Finally we have developed a loadable module in C for checking both last value items and taking more recent.

I think in the future could be some new functions for create"Calculated item" or Triggers with this behavior.
