powershell script help

I found a wonderful report online that emails me a daily report of all of my servers. Currently the report will show me the last 10 Errors and Warnings from the System event log for each server.

I would like this report to only show me these events (if any) from the last 24 hrs... but I have no idea how to edit the script to do so.

Can someone help me out?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Find attached the modified script. This will allow you to pull the list for last 24 hours. You can also modify the script to number of hours you would like to go back by changing the the value at the below line in the code.

[int]$Hours = 24

Make the following changes in lines 184 & 199 :


	$SystemEvents = Get-EventLog -ComputerName $computer -LogName System -EntryType Error, Warning -After (Get-Date).AddDays(-1)

Open in new window


	$ApplicationEvents = Get-EventLog -ComputerName $computer -LogName Application -EntryType Error, Warning -After (Get-Date).AddDays(-1)

Open in new window



We're making the change to look for one day back:
-After (Get-Date).AddDays(-1)

Open in new window
