Logging actions when using the debugger
When working with the debugger, you can track actions and their sequence. Yandex Metrica logs actions until the end of the session. This means you can log actions performed on different website pages. When you’re done, you can check different debugger tabs to analyze the collected data.
This option is available on the Console, Events, E-commerce, and Parameters tabs.
To save action logs, in the additional settings, select Preserve log. This option is disabled by default, which means that action logs aren’t saved when you refresh the page.
