Issue/Introduction

Symptoms:


How do I check the count of traps queued up in Smarts Service Assurance Manager (Smarts SAM) Trap Adapter (TA)?
How do I check the Smarts SAM trap queue depth?

How to check the number of entries backed up in the Smarts SAM trap queue using dmctl?


Smarts SAM trap processing is slow and server is showing high memory usage

Environment

VMware Smart Assurance - SMARTS

Cause

The TrapReceiverCallback sm_monitor queues or dmdebug queues are backed up.

Resolution

To check whether the TrapReceiverCallback sm_monitor queues or dmdebug queues for the Smarts SAM domain are backed up, run the dmctl dmdebug command to get the queues data and the TrapReceiverCallback value:

./dmctl -s <Domain> exec dmdebug --queues --output=queues.txt

If the TrapReceiverCallback is operating at max value (101), then trap processing will be slow or the incoming rate is very high, which can cause memory growth.
