powershell filter

, 

     #This will only send the alerts.

                          If (($SendAlert) -and (-not (((get-date).TimeOfDay.totalhours -ge 1) -and ((get-date).timeofday.totalhours -lt 4))))

                          {

                                        $Message = @"

$server is not converting

Information: $ErrorResult

**Ok ,I just need a additional line to be added on the script to remove alert and put in a filter like

-and ($errorresult notmatch "E:\Program Files (x86)\data")** , The question is ,can this be added along these lines

If (($SendAlert) -and (-not (((get-date).TimeOfDay.totalhours -ge 1) -and ((get-date).timeofday.totalhours -lt 4)))) ? or where and how it can be added effectively?

I think I'd rewrite that "if" to make it a bit less convoluted by testing for the positive instead of tossing in a "-not"?. Try this instead:

If ($SendAlert -and (((get-date).TimeOfDay.Hours -lt 1) -and ((get-date).timeofday.Hours -gt 3)))

As for you question, the answer is that you can do that, but the $ErrorResult doesn't hold a simple string. It holds an error object. I'm going to guess that the string you're looking for is in the ErrorDetails property of that object. If so, add this before the last parenthesis in the code above:

-and $ErrorResult.ErrorDetails -notlike "E:\Program Files (x86)\data"


Note that I'm using the simpler "-notlike" which makes more sense in this context since you really aren't looking to memorize the "x86" match in your regular expression and the left- and right-parentheses are part of the sting you want to match, not a group boundary.

Hi @Saravanaraj-6475 ,

I would put the last condition in brackets, like that:

  If ($SendAlert -and (((get-date).TimeOfDay.Hours -lt 1) -and ((get-date).timeofday.Hours -gt 3))-and ($ErrorResult.ErrorDetails -notlike "E:\Program Files (x86)\data"))

hope this helps.

Best Regards!

Looking again at what I suggested, the parentheses surrounding the two individual time checks and the intervening "-and" are unnecessary. They were there in the original post but they were necessary then because of the "-not". The parentheses surrounding the individual time checks are also unnecessary. This works fine:

If ($SendAlert -and (get-date).TimeOfDay.Hours -lt 1 -and (get-date).timeofday.Hours -gt 3 -and $ErrorResult.ErrorDetails -notlike "E:\Program Files (x86)\data")


You can add parentheses to lend some clarity to the thing, but they're not necessary for PowerShell to make sense of what your intentions are.

If you want to make your logic a bit more clear, you an also try this:

 If ($SendAlert -and 
     (get-date).TimeOfDay.Hours -lt 1 -and 
     (get-date).timeofday.Hours -gt 3 -and 
     $ErrorResult.ErrorDetails -notlike "*E:\Program Files (x86)\data*"
 )
