Action grid

You define the actions for a schedule in this area. You can add, modify, and delete actions. These actions include starting Vuser groups (in group schedules) and initializing, starting, and stopping Vusers. You can also define how long each action should continue.

When creating group schedules, you can copy group schedule settings from one Vuser group to another.

UI Element

Add Action After. Opens the Add Action dialog box where you can define new actions. For details, see Add Action dialog box.

The new action is added after the action selected in the Actions grid.

Example: To copy group_1's schedule settings to group_2, select group_2 in the Scenario Groups pane. Then click this button, and select group_1.

Displays the total number of Vusers scheduled to run in the scenario.
  • This is editable in basic schedules, when the scenario is in percentage mode only.

  • When the scenario is in Vuser group mode and you are defining a basic schedule, this value is updated when you modify the quantity of Vusers in the Vuser groups.

    For details, see Add Vusers dialog box.

  • In real-world schedules, the total number of Vusers is the sum of all the Vusers defined in the Start Vusers actions.

Apply. When you modify the Total: <#> Vusers field, applies the specified total number of Vusers proportionately to the Vuser groups. (Percentages are visible in the % column of the Scenario Scripts pane.)

This appears only when Total: <#> Vusers is modified.
