You should use the union operator to deliver all data from the Windows event log and Syslog. The operator takes all rows from first source and appends all data from the second source. The structure of the sources must be identical.

You should use the inner join operator to deliver only matched data from application insights and performance metrics. The inner join operator returns matching records from both sources.

You should not use the inner join operator to deliver all data from the event log and Syslog. The inner join operator requires that sources have columns that can be used as keys to perform matching.

You should not use the inner unique join operator to deliver all data from the event log and Syslog. The inner unique join operator requires that sources have columns that can be used as keys to perform matching. The inner unique join operator removes duplicates.
