Blazemeter Configuration for Load Distribution - Discrepancy

Question

I am running a test on Blazemeter by disabling the load configuration:

In the JMeter script, I have given 181 Users (total). The Load Distribution setting in Blazemeter looks like this: 2- Total Engines(Private- 50% each):

When I trigger the test I see this at the start:

During the test I see this: Max user count of 362

and then to original count (181) :

Q: Why do I see this discrepancy in total number of threads(Users)? And will I see 724 users if I change the engine count to 4? i.e. (Users given in script * Number of engines) before it returns to actual number of users?

Answer 1

If you disable BlazeMeter overrides your .jmx script is being executed "as it is", take a look at documentation:

If you do not want to use any overrides, instead relying on the configuration in your original script, you can disable any and all overrides.

Follow these steps:

1. In the Performance tab, open a test or create a new test.
2. In the Configuration tab, scroll down to the Load Configuration section.
3. Click the toggle icon for each override you want to disable. Toggled right (and blue) is enabled. Toggled left (and gray) is disabled. Once an override is disabled, the slider bar and number field is gray and will not be applied.

To disable all overrides, ensure all toggles are set to the left (gray).

When it comes to Distributed Test execution each engine runs the .jmx script as it is so

• if you have 181 user in your Thread Group and 1 engine - you will see 181 users
• if you have 181 users and 2 engines you will see 362 users
• if you have 181 users and 3 engines you will see 543 users
• etc.

Going forward you can consider reaching out to BlazeMeter Support, they should be able to offer much comprehensive help than anyone here.
