PowerShell - have trouble using the Count method - powershell

Question

I have the following code (thanks to input from 'jon Z' and 'manojlds') that processes server lists, checks the error logs for each server against a search string, and then sends an email report listing the servers with bad error logs and good error logs.
What I would like to do now is do a count of the number of servers with bad error logs and good error logs and put that info in the email report as well.
I would have something like this in each heading of my email report:
The following n servers have bad error logs:
The following n servers are OK:
I've been trying to accomplish this by using the Count method, but have so far been unsuccessful. Is the Count method the correct approach? Is so, how (where would I apply it in my code)? If not, then what is the best approach?
Code:
$BadServerLogs = "<font style=`"font-family:verdana;font-size:9pt`"><p><b>The following servers have bad error logs:</b></p>"
$GoodServerLogs = "<font style=`"font-family:verdana;font-size:9pt`"><p><b>The following servers are OK:</b></p>"
# Use hash table to associate server list to search string array
$Groups = #{
$SERVER_LST_1=$SEARCH_STR_ARRAY_1;
$SERVER_LST_2=$SEARCH_STR_ARRAY_2;
$SERVER_LST_3=$SEARCH_STR_ARRAY_3;
$SERVER_LST_4=$SEARCH_STR_ARRAY_4;
}
$StartupErrors = #{}
$Groups.keys | %{
$key = $_
gc $key | %{
# Check StartupError.log files for errors
$StartupErrors[$_] = Get-ChildItem -Path \\$_\$LOG_PATH -Include StartupError.log -Recurse | Select-String -notmatch $Groups["$key"]
If ($StartupErrors[$_])
{
$Subject = "StartupError Logs Report: BAD ERROR LOGS!"
$BadServerLogs += "<li>$_</li>"
}
Else
{
$Subject = "StartupError Logs Report: All Logs are Fine"
$GoodServerLogs += "<li>$_</li>"
}
}
}
# Send email listing servers with bad/good StartupError log files
Send-MailMessage -Body "$BadServerLogs $GoodServerLogs" -BodyAsHtml -Subject $Subject -SmtpServer $SmtpServer -To $MailTo -From $MailFrom
Thanks in advance! -Keith

You can just create two variables:
$goodCount = 0
$badCount = 0
Then in the loop increment each depending on the case:
If ($StartupErrors[$_])
{
$Subject = "StartupError Logs Report: BAD ERROR LOGS!"
$BadServerLogs += "<li>$_</li>"
$badCount += 1
}
Else
{
$Subject = "StartupError Logs Report: All Logs are Fine"
$GoodServerLogs += "<li>$_</li>"
$goodCount += 1
}
Then create some HTML and send it:
$html = "<h1>The following $badCount servers have bad error logs:</h1>" + $BadServerLogs
$html += "<h1>The following $goodCount servers are OK:</h1>" + $GoodServerLogs
Send-MailMessage -Body $html -BodyAsHtml -Subject $Subject -SmtpServer $SmtpServer -To $MailTo -From $MailFrom
