SharePoint ULS Viewer

Andreas Glaser

This tool is easily the most important resource you'll ever use as a SharePoint administrator.

"ULS Viewer is a Windows application that provides a simplified view of ULS log files in SharePoint 2013 that supports aggregation, filtering, sorting, highlighting, append, and more." (Source)

Yes it works for SharePoint Server Subscription Edition, 2019 and 2016:

SharePoint 2016 ULS Viewer


What I like the most:

  • You can attach to the live ULS log and at the same time you can filter for certain error levels and specific components. I used it once to troubleshoot the User Profile Service which had a problem while starting. I was able to see the reason for the problem right as it happened.
