If you have Load Generators Distributed in different locations
1. Do you have an application of known scalability and performance with which is assess the skew associated with the production of load from a remote location?
2. Do you have a way to measure the impact of the associated management overhead from the controller to generator traffic to ensure that it is not skewing the amount of available bandwidth available for the applications usage across the same pipe during the test?
3. Do you have licenses for many types of monitors? Monitors are not generally location specific unless you have some deep diagnostic capability that you are incorporating. In such a case you will be bound to a specific instance for the DD
4. Once again, do you have a way to monitor the overhead? Have you settled upon a sampling schema which is minimally intrusive for monitoring of remote environments, yet still which supplies the requisite information required for analysis purposes.
I have a question about environment requirements when lauching the VUsers.
If I have the Load Generators distributed in different locations (geografically):
1. I can have more than one coordinated controller machine?
2. The traffic among controller(s) and Load Generators is high?
3. Can I have different server monitors in different machines?
4. The traffic among these server monitors and the controller is high?
