The main new feature of v3.1 is the optional storage of what Qlik Sense apps are loaded, active and in_memory at each call Butler SOS does to the Qlik Sense healthcheck API.

This information can be critically important when dealing with large Sense apps that consume too much RAM when loaded from disk into RAM, potentially bringing the entire server to its knees.

Note that on a busy server with many apps loaded into RAM, enabling any of the new config options will significantly increase the amount of data stored in InfluxDB. For debugging purposes that is typically fine, but you should probably not have these new options enabled in a production setting.
