For the given track or timed clip make specify the ramp (up or down or both) using the following settings:
- Minutes to Ramp Up – Specify the minutes as an integer to ramp.
- Start Interval – Specify an interval between starts of the repeat(s) of a track. Causes "ramp."
- End Interval – Specify an interval between stops of the repeat(s) of a track. Causes "ramp down."
Ramp down assumes that parallel repeat renewal is in use since the ramp down determines whether another track repeat is spawned.
- Minutes to Ramp Down – Ramp down is also available for timed clips in clip-level composition properties (shown in screenshot above). To define a ramp down, specify the number of minutes of the ramp down or an end interval (when one is entered the UI automatically fills in the opposite one).
The goal of "ramp down" is to increment to less than the current actual number of users. Maestro doesn't "interrupt" or "abort" tracks so it must wait for individual track repeats to end naturally—which means it may not match the rate requested exactly.
- Maximum Duration – Specify the maximum length that tracks are to run. Once the maximum has been reached, new repeats will not be created. Note that maximum duration is measured from the start of the first repeat and does not include "'ramp down." Ramp down, if any, starts after the maximum duration has been reached.
The maximum duration is the sum of the ramp PLUS the intended plateau (expressed as milliseconds). For example, the screenshot above shows a ramp to 500 virtual users over 10 minutes, and then holds for 10 minutes. If no ramp down where defined in the example above, then this setup would work as it did in releases prior to Italia. Adjust the maximum duration accordingly if a ramp down will also be used (shown in the example below).
