I have a script that I run daily using a scheduled task that goes through each of my servers and e-mails me the disk space results. However, one of my servers is now using mount points and I want to be able to include these in the results.
I am fairly new to Powershell and I would like to know what to add and where to achieve this result.
Here is the code:
# Configuration data.
# Add your machine names to check for to the list:
[String[]] $servers = @("Server names here");
[float] $levelWarn = 20.0;
[float] $levelAlarm = 10.0;
[string] $smtpServer = "SMTP Server";
[string] $sender = "Email Address";
[string] $receiver = "Email Address";
[string] $subject = "US Disk usage report";
[bool] $asHtml = $true;
[string] $body = [String]::Empty;
if ($asHtml)
{
$body += "<head><title>Disk usage report</title><style>
.table {border-collapse: collapse; border: 1px solid #808080;}
.paragraph {font-family: Arial;font-size:large;text-align: left;border}
.boldLeft {font-family: Arial;font-size:large;text-align: left;border: 1px solid #808080;}
.boldRight {font-family: Arial;font-size:large;text-align: right;border: 1px solid #808080;}
.smallLeft {font-family: Arial;text-align: left;border: 1px solid #808080;}
.smallRight {font-family: Arial;text-align: right;border: 1px solid #808080;} </style></head><body>";
}
else
{
$body += "Disk usage report`n`n";
}
Clear-Host;
Write-Host "Started";
