Identifying Out of Memory events for App Pool with PowerShell"?

 Are you tired of your app pool acting up and running out of memory? Don't worry, we've got you covered. In this blog post, we're going to explore how to troubleshoot the issue and identify which app pools are running out of memory using PowerShell.

First things first, let's talk about why this issue is happening. When an app pool is running out of memory, it's usually due to a memory leak in your code or a configuration issue. This can cause your app pool to recycle, which can result in slower performance and unhappy users.

But fear not, with the power of PowerShell, we can easily identify which app pools are experiencing this issue.

Here's a PowerShell command that will help you identify the event logs for a specific app pool:

$LogName = 'System'

$EventID = 5117

$AppPoolName = 'YourAppPoolName'

$Query = @"

<QueryList>

<Query Path='$LogName'>

<Select Path='$LogName'>

*[System[(EventID=$EventID)]]

and

*[EventData[Data and (Data='$AppPoolName')]]

</Select>

</Query>

</QueryList>

"@

Get-WinEvent -FilterXml $Query -MaxEvents 30

This command will search the 'System' event log for Event ID 5117, which is the event ID that gets logged when an app pool recycles due to memory issues. It will then filter the results to only show events related to your specific app pool.

But what if you want to identify all app pools that are experiencing this issue? No problem, just remove the $AppPoolName parameter from the query below:

$LogName = 'System'

$EventID = 5117

$Query = @"

<QueryList>

<Query Path='$LogName'>

<Select Path='$LogName'>

*[System[(EventID=$EventID)]]

</Select>

</Query>

</QueryList>

"@

Get-WinEvent -FilterXml $Query -MaxEvents 30
