Question

I have the following code snippet from my PowerShell script that…

• Loops through a list of servers
• Does a Select-String -notmatch on the error log at each server
• Flags the server if the error log is bad, and gives the OK if the error log if fine

What I’d like to also do is send an email report that enumerates each of the discovered bad error logs in a list, and also list all the servers whose error logs are OK. Something like this in the email body:

The following servers have bad error logs:

• Server3
• Server6
• Server14

The following servers are OK:

• Server1
• Server2
• Server5

Here is my code snippet:

$Servers = Get-Content $ServerLst
ForEach ($Server in $Servers)
{
   $ErrorLog = Get-ChildItem -Path \\$Server\$LOG_PATH -Include Error.log -Recurse | Select-String -notmatch $SEARCH_STR
   If ($ErrorLog)
   {
    Write-Host "Bad Error Log found at $Server!"
   }
   Else
   {
    Write-Host "Error log is OK."           
   }
}

I’m guessing I would need a Send-Mail function where I would pass in the server names with bad error logs, etc. However, I’m not quite sure how to approach this.

Any great ideas will be greatly appreciated. Thanks!

If you are using Powershell V1 use this function from the Powershell Cookbook to send mail. In Powershell V2 you can send mail using Send-MailMessage.

$Servers = Get-Content $ServerLst
$Bad = "The following servers have bad error logs:`n`n"
$OK = "`nThe following servers are OK:`n`n"
ForEach ($Server in $Servers)
{
   $ErrorLog = Get-ChildItem -Path \\$Server\$LOG_PATH -Include Error.log -Recurse | Select-String -notmatch $SEARCH_STR
   If ($ErrorLog)
   {
    $Bad += "`t - $Server`n"
   }
   Else
   {
    $OK += "`t - $Server`n"           
   }
}
Send-MailMessage -Body "$Bad $OK" -Subject "Bad Logs" -SmtpServer $servername -To $to -From $from  

Remark: The smtpserver parameter is called smtphost in the Powershell cookbook function.
