Interpreting test results - Test summary Snapshots
Ive been working with openSTA for a week now, theres been some great times. Lots of testing and forum reading.
I have everything up and running (a simple browse to website using variables to request different items).
When i run my tests im trying to run 50VU's (1 Iteration), i run the tests and they say they have completed successfully however when i go to the "Test Summary Snapshots" report it seems to be telling me that it didnt run 50VU's and rather ran for example 6 "Task1 (VU's)" and 44 "Task1 (Iterations)" <- these are the column names in the test summary snapshots.
This adds up to the 50 but why is it running iterations when im asking it to run 50VU's and 1 Iteration?
If anyone can shed any light on this it would be much appreciated.
Re: Interpreting test results - Test summary Snaps
The snapshot data never completely adds up to sum of all activity. Snapshots are taken periodically. You can set the interval between snapshots, but I am unclear on how long the observation period is. Still, there will be periods of activity occurring when no snapshot is being recorded.
For a better idea on how many VUs are active see the HTTP ACTIVE USERS VS ELAPSED TIME graph (hint: you can export the graph to excel, click and drag the graph to reveal the x,y values used to create the plot). To validate the work performed, you and look at timers data to determine how many tasks (in this case, scripts) were collected in a given period. You can also export the timer data to excel for analysis. See http://portal.opensta.org/index.php?...cle&sid=43 for a spreadsheet that aggregates data in a pivot table (the count field is directly related to your questions).
