> The current unit tests for SNMP alert notifications do not provide enough of an end-to-end
coverage there should be. We should mock SNMP4J classes to ensure that the alert framework
is capable of completing an end-to-end dispatch of a trap. This includes:
> Instrumenting the SNMP4J dispatcher to intercept the SNMP message and validating the
OIDs stored
> Instrumenting Ambari alert code so that an AlertNotice is picked up and converted into
a delivered SNMP message.
> This unit test needs to cover test cases:
> 4 Verify AMBARI_SNMP trap is working fine when alerts are triggered (Need to confirm
whether covered in unit tests)
> 1 Setup a SNMP trap receiver server on one of the hosts
> 2 Create AMBARI_SNMP trap notification to use the receiver started in Step 1
> 3 Trigger an alert to be in CRIT status. E.g STOP MR to trigger HistoryServer Alert
> 4 Verify the traps are received by the receiver and verify the OID received is correct
