Ramping
During load tests using Ramp-Up/Ramp-Down, the Live view displays the ramps status. You can choose to abort the ramp process and have the test continue at the current load level, to avoid overloading.
Limitations
Note: Using the live ramp-up control feature requires that any ZebraTester scripts used are compiled with ZebraTester version 5.5F or later.

Live Ramp Introduction
The Ramping feature allows you to control Ramp-Up/Ramp-Down during a load test.
Benefits
One of the most common tasks in performance testing is to find an application's maximum throughput for a specific use case. The goal is to increase the load until the response time starts to fluctuate and the throughput flattens out. At this point increasing the load will not give more throughput just more fluctuations and increase of response time.
...
In this situation, you would benefit from having the option of interrupting the ramp-up and continue at the same level to detect the maximum point.
Feature
Working in the Live View, you an use the "abort ramp" feature to manually abort the ramp-up/ramp-down of Virtual User at a specific level during a running test. This means that the load is capped at this level.
...
Note: The abort operation is not allowed when load generation is paused or while the test is resuming .
Process
The workflow for interrupting ramping is as follows:
View the current ramping Status
Abort Ramping the ramping
Pause Load load generation
Runtime Settings according to your needs
Pause Load load generation
Status
While a test using ramp-up/ramp-down is running, the current status for the ramp process is displayed at the top of the Live View.
...
Abort Ramping
When the Abort button is available, you can interrupt the currently running ramp-up/ramp-down.
View
...
Number of users in the test can be changed only when generating load is going.
...
To change the number of users during ramp-up/down process first click "Abort ramp-up/down" button and wait until abort operation is finished.
Pause Load
The Pause Load button lets you temporarily pause loadtest traffic and set user count to 0.
...
To Resume load generation:
Click Resume Load
Runtime Settings
While a job is running, you can access the Runtime Settings and change them on the fly.
...
Note: Depending on whether ramping is aborted or not, and whether load generation is paused or not, some of these settings may not be availabel to change.
User Input
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.
...
Note: If you set the user count or duration lower than the original setting, the job will end prematurely.
