QueryFilter

A structure that defines a key and values that you can use to filter the results. The only performance events that are returned are those that have values matching the ones that you specify in one of your QueryFilter structures.

For example, you could specify Browser as the Name and specify Chrome,Firefox as the Values to return events generated only from those browsers.

Specifying Invert as the Name works as a "not equal to" filter. For example, specify Invert as the Name and specify Chrome as the value to return all events except events from user sessions with the Chrome browser.
