ExecutionLog3 Fields and Values Explained for Power BI Report Server

Hi All,

I am new to Power BI. I am attempting to build a usage metrics report for dashboards published on the Power BI Report Server. In another thread, I found that I could use the ExecutionLog3 table for this project. Upon analyzing the ExecutionLog3 table, there are some fields and possible values that I do not understand what they mean.

Thanks in avance
