This is for all the stats and metrics for the system. Essentially, all the data you see in the Performance Views. This is set to NULL meaning no time limit so no data will be deleted as long as you have a subscription. Now, here is the catch. If you set a timeframe in there, all your data beyond that date will be deleted pretty much instantly and can never be retrieved. There is no way to set it back to NULL, so you have to set to something like 99 years or 36000 days. There is not much warning so unless you have a specific reason to delete your data, don't change this.
