Sustained and ideal trap processing rate for the trap receiver

Products

• VMware Smart Assurance

Issue/Introduction

The trap adapters are defaulted to 4 processing threads. 

Environment

Smarts 10.x

TCSA 2.x

Resolution

Trap processing rates in the Smart Assurance SAM Adapters depend on the trap configuration, including mainly the hook scripts invoked and the execution of the findComputerSystem call.

The ideal rate without any kind of delay should be around 30-40 traps per second, with 4 trap processing threads. The average trap processing rate observed for most environments is around 10-15 traps per second. These numbers are very subjective should be considered only general guidelines as the processing rate number can be significantly impacted by both the network and the trap configuration.

The thread counts of 4 can be increased as needed up to a maximum value of 25. 

Example: To change the trap adapter to run with 10 threads

bin/sm_edit conf/trapd/trapd.conf

change
#THREADS: 1

to

THREADS: 10

Restart the trap adapter for the updated settings to take effect.

Note: Each additional thread will consume additional memory and cpu resources on the server. Please ensure that you have sufficient resources before increasing the thread count value.
