This is another “Wow that was easy!” SharePoint items…
Open Central Admin
Go to the Monitoring section, then under “Timer Jobs”, select “Review job definitions”
There’s a timer job called “Diagnostic Data Provider: Trace Log”
It’s disabled by default, enable it and it will create new tables and a view on your logging database. (I think by default this is named WSS_Logging)
Leave it enabled (mine is set to run every 10 minutes)
Open SQL server Management studio and connect to your sharepoint DB server.
expand the WSS_Logging DB
Look for the new view called “ULSTraceLog”
I usually right click on the view name and “Select Top 1000 Rows”
Then from there I can add a where clause to the query thats on screen,
most often it’s
WHERE CorrelationID = ‘abcd-efg-hijk-lmnop-qrstuv’
Another tip- in the results (which on my system default to the “grid” view),
Right Click, Select All, then
Right Click, Copy with headers
you can then paste this into Excel and it’s pretty readable if you need to email it to someone.
As a side note, I’ve enabled this on a handful of farms and it seems to auto trim the DB sizes – so you don’t need to worry about the DB filling up over time.
