Plugin enables sending events to Yandex.Metrica and Google Analytics. The chat has its own documentation regarding event tracking in counters; the up-to-date documentation can be found on the chat's website.
In Google Analytics, data is automatically sent via the counter connected in Settingsch >Web Systems Pro<. Make sure you have entered the Google Analytics Property ID in the admin panel under Site -> Settings website -> Google Analytics Property ID.
To view the number of tracked events in Google Analytics, navigate to Behavior -> Events -> Top events.

Unlike Google Analytics, in Yandex.Metrica you must manually add all events. This is done in the section Settings -> Goals -> Add goal.

In the window, fill in the following:
Name - any name (e.g., Widget - "Goal name")
Select condition type JavaScript event
Goal ID - specify the corresponding event from the list below

It is not necessary to configure all goals immediately; you may set up only the essential ones.
