The dreaded Correlation ID! It is fine when you have a few servers in your farm. However, if you manage a huge farm finding the error can be time-consuming Instead of searching every server in the farm logs to match the correlation ID, the Merge-SPLogfile cmdlet allows an admin to create one logfile from the correlation ID. The cmdlet will search every server in the farm and match the correlation ID and make one single log file.

Here is an example:

Merge-SPLogfile –Path “C:\SP2013\ErrorLogs\mergedlogs.log” –Correlation <Correlation ID>

When you receive the Correlation ID from a user outside the twenty-minute window, you need to do provide a general start time/date and end time/date. In this example, the user tells me that the Correlation ID was received around today from 1pm to 3pm.

Here is an example:

Merge-SPLogfile –Path “C:\SP2013\ErrorLogs\mergedlogs.log” –Correlation <Correlation ID>

-StartTime “03/18/2016 13:00” –EndTime “03/18/2016 15:00”
