Failure retrieving Diagnostics Logs location

Question

I've been getting these Unexpected ULS entries from Timer Job hourly-all-sptimerservice-health-analysis-job:

Failure retrieving Diagnostics Logs location:
System.ArgumentException: Object must be a root directory ("C:\") or a drive letter ("C").
at System.IO.DriveInfo..ctor(String driveName)
at Microsoft.SharePoint.Administration.Health.AppServerDrivesAreNearlyFull. GetDrivesForValidation()

Does anyone know what is this about?

Answer 1

Did you change the default Diagnostics Logs location? By default, SharePoint log files are saved to the following location: "C:\Program files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS".

From the error message, it showed there was something wrong with the logs location, check it and make sure it matches the correct format.
