I have prepared server health report via PowerShell. My script is working fine but I am getting some random value in the bottom when I receive email via script, also I am not able to add body in my send-mailmessage command. When I do so script generates exception.
Here is my PS code:

Below is my attached output and that * and 1121 is that random number:
Utilization of Server Resources
Server Name CPUUtilization Memory Utilization CDrive
xxxxxxxx 3.25% 29.26% 22.11%
xxxxxxxx 18.80% 52.15% 57.49%
xxxxxxxx 27.76% 27.51% 71.91%
*
1121
I have changed the $out variable and added property attribute in it and that worked. Here's my edited $out command
$out=$Outputreport | ConvertTo-Html -Property Servername,CPUUtilization,MemLoad,CDrive -Head $Outputreport

I have developed PowerShell script which monitors server performance like average CPU utilization, Memory and Cdrive and if any of the resource crosses the threshold it will trigger mail. My script is running fine but I want to monitor it for 30 minutes and if in 30 minutes it cross threshold only then it will trigger the mail.

Please do suggest me if any changes are required in any of the command as well.
This should give you an idea on how to run jobs in the background and check for 30 minutes. If at any time the cpu, mem or disk is greater than threhold, send email.
function SendEmail {
param($server, $cpu, $mem, $disk)

}

$memThreshold = 99
$diskThreshold = 100
$jobHash = #{}

$serverList = #("localhost")
foreach($server in $serverList) {
$cpu = Start-Job -ComputerName $server -ScriptBlock { Get-Counter "\processor(_Total)\% Processor Time" -Continuous }
$mem = Start-Job -ComputerName $server -ScriptBlock { Get-Counter -Counter "\Processor(_Total)\% Processor Time" -Continuous }

$serverHash.Add("cpu", $cpu)

$serverHash.Add("disk", $disk)
$jobHash.Add($server, $serverHash)
}
Start-Sleep 10
$totalLoops = 0
while ($totalLoops -le 360) {
foreach($server in $jobHash.Keys) {
$cpu = (Receive-Job $jobHash[$server].cpu | % { (($_.readings.split(':'))[1]).Replace("`n","") } | measure -Maximum).Maximum
$mem = (Receive-Job $jobHash[$server].mem | % { (($_.readings.split(':'))[1]).Replace("`n","") } | measure -Maximum).Maximum
$disk = (Receive-Job $jobHash[$server].disk | % { (($_.readings.split(':'))[2]).Replace("`n","") } | measure -Maximum).Maximum

}
Write-Output "CPU: $($cpu), Mem: $($mem), disk util: $($disk)"
}
Start-Sleep 1

}
Get-Job | Remove-Job
Hopefully this answers the question on how to create jobs in the background to check for status.
I would, however, check the max number of jobs you can have at any given time.
Documentation on Get-Counter
I have the below PowerShell script which shows the remote servers CPU/Disk/Memory health check.
It is not giving the output in HTML format and I am sending it to my email id with SMTP option. It is all working fine.
Current Output:
Along with the HTML output I want this output to be saved in a CSV file as well so that I can load it into Teradata using MLOAD.
Please help me to get output in a CSV file.
How can we load the data in CSV file to Teradata, can this be done using powershell or batch?

As $result already contains the info you want in the csv, it can just be piped to Export-Csv
Simply add this line at the end of your script:
$result | Export-Csv -Path C:\folder\health_check.csv -NoTypeInformation
Not used Teradata but there was already a question on csv import: How to load data from a csv file into a table using Teradata Studio
All you need to do is, append to your script:
$Result | Export-Csv "C:\Users\HOSDUM01\Desktop\Auto\Server_health_check\Test.csv" -NoType
or whatever path you'd like to store the file
EDIT Reworked the script out of interrest.
Streamlined path usage
Inserted function DriveFreePercent and removed intermediate (unneccessary) variables.
moved the html creation outside of the foreach

I am using a script that performs a basic health check on average CPU and Memory Utilization and checks if a specific service is running or not. The output will be displayed as HTML. If the CPU/Memory utilization is greater than 89%, or if ther service is not running, the affected server will be displayed in red. The script works just fine except for some inconsistencies that the server, even when under utilized, will be in red.
Here is the powershell script I am using:
$ServerListFile = "C:\Scripts\HealthCheck\ServerList.txt"
$ServerList = Get-Content $ServerListFile -ErrorAction SilentlyContinue
$Date = Get-Date -Format M.d.yyyy
$Result = #()
foreach ($computername in $ServerList) {
$AVGProc = Get-WmiObject -ComputerName $computername Win32_Processor |
Measure-Object -Property LoadPercentage -Average |
Select-Object Average
$OS = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $computername |
Select-Object #{Name = "MemoryUsage"; Expression = {"{0:N2}" -f ((($_.TotalVisibleMemorySize - $_.FreePhysicalMemory)*100)/ $_.TotalVisibleMemorySize) }}
$Service1 = Get-Service -ComputerName $computername -Name Service1
$Service2 = Get-Service -ComputerName $computername -Name Service2
$Result += [PSCustomObject] #{
ServerName = "$computername"
CPULoad = "$($AVGProc.Average)%"
MemLoad = "$($OS.MemoryUsage)%"
Service1 = "$($Service1.Status)"
Service2 = "$($Service2.Status)"
}
$Outputreport = "<HTML><TITLE> Server Health Check </TITLE>
<BODY background-color:peachpuff>

foreach ($Entry in $Result) {

Thanks!
Don't use string comparisons when you're really interested in a numerical comparison - the ordinality of a string of digits is not equal to that of it's numerical counterpart. Consider the following comparison operations:
PS C:\> 9 -gt 89
False
PS C:\> "9" -gt "89"
True
First, change the result objects to carry the percentages as numbers instead:
$Result += [PSCustomObject] #{
ServerName = "$computername"
CPULoad = $AVGProc.Average
MemLoad = $OS.MemoryUsage
Service1 = "$($Service1.Status)"
Service2 = "$($Service2.Status)"
}
Then change the if statement to compare them as numbers:
if (($Entry.MemLoad -gt 89) -Or ($Entry.CPULoad -gt 89) -or ($Entry.Service1 -eq "Stopped") -or ($Entry.Service2 -eq "Stopped"))
And then finally, add the % sign in the final output:
$Outputreport += "<TD>$($Entry.Servername)</TD><TD align=center>$($Entry.CPULoad)%</TD><TD align=center>$($Entry.MemLoad)%</TD><TD align=center>$($Entry.Service1)</TD><TD align=center>$($Entry.Service2)</TD></TR>"

you arent capturing the get-eventlog return values
ForEach($computername in $ServerList)
{
$eventLog = Get-Eventlog -LogName Security -Newest 2000 | Where-Object {$_.EventID -eq "4624"} | Select-Object #{Name ="Username"; Expression = {$_.ReplacementStrings[1]}}
$result += [PSCustomObject] #{
ServerName = "$computername"
EventLog = "$eventLog.Username"
}
if what you want is an entry in result for each of the 2k event log items returned then do this:
ForEach($computername in $ServerList)
{
$eventLog = Get-Eventlog -LogName Security -Newest 2000 | Where-Object {$_.EventID -eq "4624"} | Select-Object #{Name ="Username"; Expression = {$_.ReplacementStrings[1]}}
foreach($item in $eventLog)
{
$result += [PSCustomObject] #{
ServerName = "$computername"
EventLog = "$eventLog.Username"
}
}
I incorporated the changes suggested by Dane Boulton and modified your code a bit to get what I believe is what you are looking for. I changed the Replacement strings entry to 5 because I believe you are looking for the user account logging in. I also modified the EventLog variable to reference $item.UserName. See how this works for you.
$ServerListFile = "D:\Scripts\ServerList.txt"
$ServerList = Get-Content $ServerListFile -ErrorAction SilentlyContinue
$Result = #()
ForEach($computername in $ServerList)
{
$eventLog = Get-Eventlog -LogName Security -Newest 2000 | Where-Object {$_.EventID -eq "4624"} | Select-Object #{Name ="Username"; Expression = {$_.ReplacementStrings[5]}}
foreach($item in $eventLog)
{
$result += [PSCustomObject] #{
ServerName = $computername
UserName = $item.Username
}
