Hi Friends


Please suggest  on below  requirement  from one of my client

 ==================================================================

  • Need to  capture the packet loss/down  event in log buffer  for NQA

 

For instance , for nqa test-instance 1 LAN_To_HUBLAN, if partial packet loss or 100%packet loss   per probe is observed , an alarm  should be   generated and should be captured in logbuffer .

 

Tried  with  configuring  alarm 1 lost-packet-ratio absolute falling-threshold 1 1 rising-threshold 1 1 description "LAN to  LAN down "

 

but  didn’t work  , observing alarm as while NQA has no  packet loss

 

Jul 28 2019 10:54:30+05:30 VPPO-RKT101-RTR1001 %%01NQA/4/FALLING_ALARM(l)[0]:The 2 defined in nqa alarm table(OwnerIndex = 1 TestName = LAN_To_HUBLAN AlarmEntryNumber = 1)has alarm value 0,less than threshold 1. It's alarm sample type is 2.

@yogijain Hi,
the NQA test instance will test for x(probe-count) times, in the current scenario, probe count is 2. If one of the two test is normal, the result for the current NQA test instance is normal. And you configured [alarm 1 lost-packet-ratio absolute falling-threshold 1 1 rising-threshold 1 1 description "LAN to LAN down "],
Assume that the first ICMP test failed, and the second ICMP test successed, then the current NQA test is success, but the packet loss ratio is 50% which is over the falling-threshold and rising-threshold, then the alarm generates.
I think you can try to adjust the rising-threshold to 100, and bind another event-entry to the rising-threshold, and check the event-entry of the alarms generated by the NQA is the based on falling-threshold or the rising-threshold

NQA/4/FALLING_ALARM

Description: The value of the monitred node was below the lower limit.
Possible Causes:The value of the monitored node was below the lower limit.

Procedure:

1.Run the display nqa-agent command and check alarm entry-number jitter-average absolute falling-threshold to see the threshold value is proper. 
a. If the lower limit is too large, run the alarm command to set the lower limit to be a proper value, and then go to 3.
b. If the lower limit is proper, go to 2.

2.If the alarm is generated because of a network problem, check the configurations and services of the network, and contact technical support personnel.

3.End.
