You have 100 computers that run Windows 10 and connect to an Azure Log Analytics...

You can collect error events from the System log, third-party application logs stored as text files, and the average processor utilization from the computers by using Log Analytics. These are some of the types of data that you can collect by using data sources such as Windows event logs, custom logs, and performance counters. You cannot collect failure events from the Security log or the list of processes and their execution times by using Log Analytics.
