Using the PowerShell cmdlet Get-WinEvent to search and filter event and diagnostic logs

28 Sep 2016 — Administration

Recently, a colleague wanted a way to search the body of Windows eventlogs – for instance if you wanted to count the occurances of a certain type of event where the traditional filtering fields are unable to differentiate between events.

The powershell cmdlet Get-WinEvent output can be piped into where-object to provide a set of events filtered by the search term in the eventlog body.

Get-WinEvent -FilterHashtable @{logname='application'; ProviderName='ASP.NET 4.0.30319.0'} | where-object  { $_.Message -like '*The timeout period elapsed prior to obtaining a connection from the pool*' }

Thanks Matt.
