There are times when you wish to track changes in performance for certain types of requests, urls, over a period of time.
For example, after go lives, code changes, update sets, etc. This can be done by building out the following example reports.
Other options could be to modify the Aggregation field from 'Client Response Time' to 'Browser Time' or 'Client Script Time' - for example if you're trying to track how long browsers take to render forms, or how much time Client Scripts take to run over your report time period.
Create the following reports to track Forms, Reports, Lists, All transactions.
You can also add a date range so that you can then run it week by week (schedule the report).
You can also add TYPE = form / list / report / (or none for all client transactions).
Note: As this data is coming from the transaction log table, 'Client Response Time' is in ms - therefore 14,000 = 14 seconds.
