Load generators are used to simulate actual users while running the load tests. Load controller contact the load generators and sends the scripts on the load generators to simulate the vusers.
It is very important to have a few load generators to support the load. It is equally important to monitor the load generators during the performance test as it is important to monitor the IT architecture that is being load tested.
In our scenario, the load generators were running out of the Physical memory and hence, the response time was getting impacted. You can configure site scope to monitor all the load generators in load controller itself.
Watch for memory consumption on the load generators to make sure there is enough memory available for the vusers. CPU should not be a concern on these generators since there is no CPU intensive processing on these machines.
Specific question, concern or comment? Please leave a note and I would be glad to respond.
