I am a very big fan of the PAL tool to assist in sifting through event logs when diagnosing server or environment issues. One thing is doesn’t come with is a threshold file specifically for SharePoint 2010.
Luckily I have saved you the need in creating one from scratch and you can download the SP2010 threshold file from the links below.
I have tested the threshold file with PAL 2.07 and 2.08.
Let me know your thoughts and I will be creating a FAST and SharePoint search specific ones in the near future.
To install simply copy the .xml to the C:\Program Files\PAL\PAL vx.x.x folder and you should be good to go
