Finding the Most Important Event Log Error Sources

by Jun 19, 2015

If you don't have much time yet would like to know what the most common sources of errors are in your System event log, try this line:

Get-EventLog -LogName System -EntryType Error, Warning |
 Group-Object -Property Source |
 Sort-Object -Property Count -Descending

Once you found a source that caused a lot of errors (or warnings), this line would provide you with the error details:

# change this variable to the name of the source you want
# to explore:
$source = 'Schannel'
Get-EventLog -LogName System -Source $source |
