We have an application that has a temporary folder where files reside before
being processed. We know there is an issue if the files exist in this directory
for a lengthy period of time. Some of these files come from outside locations,
so we can’t use “Date Modified” as they will sometimes already be >30mins old
when they arrive in this temporary directory. So we want to alert when files
exist for longer than 30mins in the temporary directory. I was attempting to
use the below command, but it’s not behaving as I would expect.
(Get-ChildItem $directory | Where-Object {$_.CreationTime -ge
(Get-Date).AddMinutes(-30)} | Measure-Object).Count
That command returns a count of “0” even though the file has existed for
>30mins (over 180mins at this point). When I get the properties of the file, it
lists the creation date in the following format:
Name : Dummy_File.txt
Length : 5801
CreationTime : 4/23/2015 8:53:48 AM
LastWriteTime : 1/20/2015 9:48:12 PM
LastAccessTime : 4/23/2015 8:53:48 AM
I am wondering if the time comparison doesn’t work how I envision it working.
When I switch to using “-le” the same thing happens, except it constantly
returns “1”.
The end goal is to wrap this in a Management Pack and alert via SCOM, but the
manual execution is not returning accurate results. Do I have to format the
date/time differently in order to perform a proper calculation?
Thank you.
