How do I Configure Workloads

Load details have to be configured in the Web Performance UI. Select the appropriate Load Test from the left-side screen and configure load details as per your requirement. The options available with loads are as follows:

Select any one of the following Load Types and configure its details as explained in the following links.

In this type of load, a constant number of virtual users are run against the web application for the duration of the test. In normal mode, assume the number of users are 5, number of times to run is 2. For this load, five users will be simulated and will perform the load test. After all the five users complete the transaction, all the five users will be simulated and will perform the load test for the second time. After all the users complete execution for the second time, reports will be generated and shown describing the metrics collected during the load test.

In this type, an increasing load is run for the duration of the test to help testers find the limit of a web application’s work capacity. At the beginning of the load test, only a small number of virtual users are run. Virtual users are then added to the load step by step.

In this type of load, at the beginning of the load test, a maximum number of virtual users are simulated based on the specified value. Virtual users are then removed from the load in a step by step approach at the specified time intervals. For example, assume first 50 users are run and at an interval of every 2 seconds, 10 users are removed from the load to ramp down from the peak value to the lowest value.

In this type of load, the test will be executed until any of the configured exit criteria is reached. The number of times also will account for test execution.

Assume your website experiences normal load during early morning hours, peak load during the key business hours (say from 9.00 a.m. to 12:00 a.m.) and in the late evening, the user load gradually slows down. To emulate this real-world load behavior, QEngine provides the Mixed Load type model. Mixed Load type allows you to add a combination of load such as (SteadyLoad and Ramp-up) or (SteadyLoad, Ramp-up and Ramp-down) or (Ramp-down and Ramp-up). In this load model, you can simulate a steady-state load (minimal users) for first 2 hours, then simulate a heavy load in the next 3 hours to emulate the peak load generated in the key business hours and remain in the steady-state for few hours and then simulate the ramp-down load where users gradually decrease from a steady-state to a lowest value. You can configure the following parameters for Mixed Load type:

Parameter	Description
Number of Users	Enter the number of virtual users to be simulated.
Run for the completion of	Enter the number of times the transaction should be replayed with the specified number of virtual users for the given number of times. For example, Load type = 'Normal' Number of Users = 4 Run for the completion of Choose either "Number of Repetitions" or "Time Duration" In case of Number of Repetitions, the test will be executed given number of repetition and stop. In case of Time Duration, the test will be executed for the configured time duration and stop. Here you can configure the test to execute for Minutes / Hours / Days.

Parameter	Description
StartsWith	The starting number of virtual users.
Increment Users Every Seconds	The "Increment" value is how many virtual users to add in a period or after the specified number of seconds. The period value is specified in seconds in the field adjacent to the Increment field.
Limit To	The maximum number of virtual users to simulate during the test.
Number of Times	The number of times the transaction should be replayed (Optional) If the Number of Times is not specified, the user will be added to the loadtest every given frequency without disturbing already running virtual user. After adding the last set of virtual user the test will run for one repetition and report will be generated. If the number of times is configured, then the each and every virtual user will be executed for the maximum of configured repetitions and then stop. After all the user completing all the repetitions the test will be stopped and reports will be generated.

Parameter	Description
StartsWith	The starting number of virtual users.
Decrement Users Every Seconds	The "Decrement" value determines how many virtual users should be removed from the load in a period or after the specified number of seconds. The period value is specified in seconds in the field adjacent to the Decrement field.
Limit To	The minimum number of virtual users to be simulated after which the test stops execution.
Number of Times	The number of times the transaction should be replayed (Optional) If the Number of Times is not specified, the user will be removed from the loadtest every given frequency. After removing the limit to users the test will run for one repetition and report will be generated. If the number of times is configured, then the each and every virtual user will be executed for the maximum of configured repetitions and then stop. After all the user completing all the repetitions the test will be stopped and reports will be generated.

Parameter	Description
Number of Users	The number of virtual users to be simulated.
Exit on Server Crash	To exit the performance test if the web server crashes.
Exit if Test Duration	To exit if the test duration exceeds the specified time in milliseconds.
Response time less than	To exit if the response time is less than the specified milliseconds for the specified percentile of the time.
Exit if CPU% on exceeds	To exit if the CPU of the specified server exceeds the specified CPU %
Number of Times	The number of times the transaction should be replayed.

Load Type	StartWith (Users)	Ramp Up/Down (users)	For Every	Total Duration	EndWith
From the Load Type combo, select the load type as SteadyLoad, Ramp-up or as Ramp-down.
For SteadyLoad	Enter the number of virtual users to be simulated to emulate a steady-state load.	In case of SteadyLoad, this is not applicable.	In case of SteadyLoad, this is not applicable.	Enter the total test duration before which all the URLs should be load tested with the configured load.	In case of SteadyLoad, this is not applicable.
For Ramp-up	Enter the starting number of virtual users to be simulated to emulate the peak-load testing.	Enter the increment value or how many users should be incremented at periodic intervals before reaching the endwith user limit value.	Enter the interval at which the number of users should be incremented from the current value.	Enter the total test duration before which all the URLs should be load tested with the configured load.	This is automatically generated by QEngine based on the StartWith and Ramp up value
For Ramp-down	Enter the starting number of virtual users from which the users should be dropped-down or decremented.	Enter the decrement value or how many users should be decremented at periodic intervals before reaching the endwith user value or the lowest value.	Enter the interval at which the number of users should be decremented from the current value.	Enter the total test duration before which all the URLs should be load tested with the configured load.	This is automatically generated by QEngine based on the StartWith and Ramp down value.
