Check a object-string against a array of exceptions - arrays

Question

I got a bunch of objects containing multiple string values. I want to manage the exceptions with a object/array consisting of multiple more and less known exceptions. Is there a simple way to get this to work? afraid my brain ain't made for this kind of problemsolving.
Example:
Exceptions =#{
Known1 = 'Minor Error'
Known2 = 'This Have We Seen Before'
Known3 = 'I Remember This Issue'
Special1 = 'Application malfunction'
Special2 = 'Application malfunction severe!'
}
$AllCases = Get-Cases
Foreach ($Case in $AllCases){
if ($Case.Name -match $Exceptions.Values.('^Known+[0-9]$')){'Do That again'}
Elseif ($Case.Name -match $Exceptions.Values.Special1){'OBS! Do This Fast'}
Elseif ($Case.Name -match $Exceptions.Values.Special2){'SEVERE OBS! do this faster!'}
}
Thanks :)

I guess you're trying to create a script to identify incidents where $case.Name whatever that could be (subject of the incident?) matches with your map of words that are commonly found, which in turn points to a specific Error Code or Error Index? If that's the case, It is probably better even though slower, to store a separate CSV file where you can add new Error Indexes and make your script read this CSV each time. In any case, I harcoded an example of how the CSV could look like and added some comments to guide you with the tought process.
$Exceptions = #"
Index,Error
Known1,Minor Error
Known2,This Have We Seen Before
Known3,I Remember This Issue
Special1,Application malfunction
Special2,Application malfunction severe!
"# | ConvertFrom-Csv
# I'll generate 500 random cases here mixing the words on Error
# I'll also added a IncidentNumber property becase I'm guessing you have something like that
$words = $Exceptions.Error -split '\s'
$AllCases = 0..500 | ForEach-Object {
$ran = Get-Random -Minimum 2 -Maximum 10
[pscustomobject]#{
IncidentNumber = Get-Random
Name = ($words | Get-Random -Count $ran) -join ' '
}
}
Example of the cases created
PS /> $AllCases | Get-Random -Count 5
IncidentNumber Name
-------------- ----
2043166219 Application This Remember Before
837011116 malfunction Error Seen Have malfunction Issue Minor severe!
2103904733 This malfunction We This I Have Seen Application
323914959 Minor This Issue Remember This Application Have Seen
1105202359 malfunction Seen We This I malfunction
Back to the script:
$result = foreach($Case in $AllCases)
{
if($Exceptions.Error -match $Case.Name)
{
# Note: I'm using -match here instead of -in or -contains
# because we want to partially match, considering that $Case.Name
# could be a much longer string
# $Exceptions array where the string in $Case.Name
# matches any element of $Exceptions.Error
$Exceptions.Where({$_.Error -match $Case.Name}) |
Select-Object #{n='IncidentNumber';e={$Case.IncidentNumber}},Index,#{n='Status';e={'FOUND'}}
continue
}
# If there are no matches you can use something like below, not sure
# you have some sort of incident number or something short you can use
# for those incidents not found :)
$Case | Select-Object IncidentNumber,#{n='Index';e={$null}},#{n='Status';e={'NOT FOUND'}}
}
Since this is all random, it is possible there will not be any matches but in this run I got these results
PS /> $result | Sort-Object Status | Select-Object -First 10
IncidentNumber Index Status
