Hi Lakshani,
Thanks to Infar team we got 4GB memory in gateway instances. Now we can
proceed.
Please find the below clustering environment configuration [Table 1] which
we will be using for AppM load testing. Shall we start writing Jmeter
scripts for below testing scenarios [Table 2] as well?

How to proceed
Goal and test output
Capacity/Load Test
Gradually increase the number of hits to gateways by looking at the CPU
load average and JVM memory utilization. We keep increasing hit count until
performance or stability become unacceptable in gateway nodes.
Goal - Measure how many concurrents hits can handle by the gateway
successfully.
Output - In a cluster environment with 2 gateway nodes which having a 4GB
memory in each instance, AppM can handle up to n concurrent hits without
any performance or stability issues.
Stress Test
Load the gateway beyond the normal load condition. Push it to the extreme.
Goal - We will see which components fail first. Making these components
more robust.
