Do you know what is Web Statistics? Web Statistics is a feature to trace troubleshoot problems in your environment. You can see what is going with your slow report, for example.
You can see those logs in two ways: screen or file or screen and file.
So, to enable these statistics, you just have to:
1. Go to Web Administrator:
2. Under Diagnostics -> Statistics
3. Choose your mode
4. If you chose File or Screen and file mode, you must give a path so MicroStrategy Web can save this log for you.
In my case, I chose Screen and the result is something like this:
Now you can analyse your environment with this log.
Hope it helps!
God bless you!
