PowerShell WinEvent FilterHashtable wildcard

This is my first time working in PowerShell. I'm trying to filter events based on Date only.

According to the documentation, Logname and Providername accept wildcard characters.

How can I wildcard the Logname ? I have tried *, ** but it does seem to work.

Get-WinEvent -FilterHashtable @{Logname=*; StartTime=$startTime; EndTime=$endTime}
Solution

  • I don't think you can. Here's how I get around it. You can't even do this in event viewer, events from all logs within a certain time. There's an old windows api limit to the number of lognames. Foreach-object -parallel in powershell 7 is faster.

    Get-WinEvent -ListLog * -EA silentlycontinue | 
foreach-object { get-winevent -filterhashtable @{logname=$_.logname; 
  starttime='1:55 pm'; endtime='1:58 pm'} -ea 0 } 

    # powershell 7
get-winevent -LogName *

Get-WinEvent: Log count (458) is exceeded Windows Event Log API limit (256). 
Adjust filter to return less log names.
