Runtime Settings
While a job is running, you can access the Runtime Settings and change them on the fly.
Setting | Description | Comment |
|
|---|---|---|---|
| Users | Number of virtual users. | You can only decrease existing users. Decreasing users to zero will stop the job when zero users is reached. |
Startup Delay | Time for Ramp Up to use when increasing number of users. | Applied when increasing user count after a previous decrease. |
|
Duration | Load test job duration. |
|
|
If you add a change while a previous change is still running, the processes will run in parallel.
Depending on whether ramping is aborted or not, and whether load generation is paused or not, some of these settings may not be available to change.
When scripts used in the load test contain User Input Fields, these can also be updated in real time.
Change Settings
You can change the Runtime Settings for any job that is currently running.
Change Runtime Settings
Start with a running job.
Click the Change Runtime Settings button
The Real Time Settings dialog opens.
Change settings as needed
Click Update Job Settings
Note: If you set the user count or duration lower than the original setting, the job will end prematurely.
