During a run, you can increase or decrease the number of
virtual users that was defined in the schedule. You can apply the
change to the current stage or to all the remaining stages in the
schedule.
Before you begin
You must run a schedule to change the number of virtual users.
Procedure
- In the Test Navigator view, double-click
a schedule and click Run from the schedule
editor.
- Click .
- To add users, type the number of users to add. To remove
users, click Remove users, and type the number
of users to remove.
Note: - If a schedule contains only percentage groups, the virtual users
are added by proportion. Assume that your schedule contains three
user groups, assigned at 20%, 30%, and 50%. If you add 10 virtual
users, two are added to the first group, three are added to the second
group, and five are added to the third group.
- If a schedule contains both absolute and percentage groups, the
absolute groups are assigned first. Assume that your schedule has
one user group that is fixed at 10 users and only one virtual user
is running in that group. You add 100 virtual users. Nine virtual
users are added to the absolute group, and the remaining virtual users
are apportioned among the percentage groups.
- Users are removed proportionately from user groups according to
each user group's percentage value. The time at which users are asked
to stop is controlled by the change rate that you set in the schedule.
- Optional: To apply the change to all remaining
stages in the schedule run, select the Apply to all remaining
stages check box. Clear the check box to apply the change
only to the current stage.
- Click OK. To see the
number of users executed, check the Summary tab
of the performance report.
