PowerShell script for server information in an email report

PowerShell script that gathers server CPU and memory utilization, disk space, and uptime, generates a report, and sends it via email to IT Support. This script uses WMI and requires SMTP configuration for email functionality.

# **Configuration Section**
$SMTPServer = "smtp.yourdomain.com"  # Replace with your SMTP server
$SMTPPort = 587                     # Replace with your SMTP port (e.g., 25, 587)
$EmailFrom = "server-report@yourdomain.com"
$EmailTo = "itsupport@yourdomain.com"
$EmailSubject = "Server Health Report"
$SMTPUsername = "your-email-username"  # Replace with your SMTP username
$SMTPPassword = "your-email-password"  # Replace with your SMTP password

# **Gather Server Information**
$ServerName = $env:COMPUTERNAME
$CPU = Get-WmiObject Win32_Processor | Measure-Object -Property LoadPercentage -Average | Select-Object -ExpandProperty Average
$Memory = Get-WmiObject Win32_OperatingSystem
$TotalMemory = [math]::Round($Memory.TotalVisibleMemorySize / 1MB, 2)
$FreeMemory = [math]::Round($Memory.FreePhysicalMemory / 1MB, 2)
$UsedMemory = [math]::Round($TotalMemory - $FreeMemory, 2)
$DiskInfo = Get-WmiObject Win32_LogicalDisk -Filter "DriveType=3" | ForEach-Object {
    [PSCustomObject]@{
        DriveLetter = $_.DeviceID
        FreeSpaceGB = [math]::Round($_.FreeSpace / 1GB, 2)
        TotalSpaceGB = [math]::Round($_.Size / 1GB, 2)
        UsedSpaceGB = [math]::Round(($_.Size - $_.FreeSpace) / 1GB, 2)
    }
}
$Uptime = (Get-WmiObject Win32_OperatingSystem).LastBootUpTime
$UptimeFormatted = (Get-Date) - ([Management.ManagementDateTimeConverter]::ToDateTime($Uptime))

# **Generate Report**
$Report = @"
Server Health Report for $ServerName

CPU Utilization: $CPU%
Memory Usage: $UsedMemory GB used out of $TotalMemory GB
Disk Usage:
@($DiskInfo | ForEach-Object { "Drive: $($_.DriveLetter) - Free: $($_.FreeSpaceGB) GB, Used: $($_.UsedSpaceGB) GB, Total: $($_.TotalSpaceGB) GB" }) -join "`n"
Uptime: $([math]::Floor($UptimeFormatted.TotalDays)) days, $($UptimeFormatted.Hours) hours, $($UptimeFormatted.Minutes) minutes
"@

# **Send Email**
Send-MailMessage -From $EmailFrom -To $EmailTo -Subject $EmailSubject -Body $Report -SmtpServer $SMTPServer -Port $SMTPPort -Credential (New-Object PSCredential($SMTPUsername, (ConvertTo-SecureString $SMTPPassword -AsPlainText -Force))) -UseSsl

Key Notes:

1. SMTP Configuration: Replace placeholders with your actual SMTP server details and credentials.
2. Permissions: Ensure the script is run with sufficient privileges to access WMI and send emails.
3. Disk Filtering: The script filters only local drives (DriveType=3).
4. Customization: You can modify the email body or add additional metrics as needed.

This script is designed to be run on a Windows server.

# Define variables
$SMTPServer = "localhost"  # Replace with your SMTP server if not localhost
$From = "server-report@yourdomain.com"
$To = "itsupport@yourdomain.com"
$Subject = "Server Disk Space and Uptime Report"
$Body = @()

# Get server uptime
$Uptime = (Get-CimInstance Win32_OperatingSystem).LastBootUpTime
$UptimeFormatted = (Get-Date) - $Uptime
$Body += "Server Uptime: $([math]::Floor($UptimeFormatted.TotalDays)) days, $($UptimeFormatted.Hours) hours, $($UptimeFormatted.Minutes) minutes`n"

# Get disk space information
$Body += "Disk Space Report:`n"
$Disks = Get-CimInstance Win32_LogicalDisk -Filter "DriveType=3"  # Only fixed drives
foreach ($Disk in $Disks) {
    $FreeSpaceGB = [math]::Round($Disk.FreeSpace / 1GB, 2)
    $TotalSpaceGB = [math]::Round($Disk.Size / 1GB, 2)
    $UsedSpaceGB = $TotalSpaceGB - $FreeSpaceGB
    $PercentFree = [math]::Round(($FreeSpaceGB / $TotalSpaceGB) * 100, 2)
    $Body += "Drive $($Disk.DeviceID): $UsedSpaceGB GB used, $FreeSpaceGB GB free ($PercentFree% free)`n"
}

# Convert body to string
$Body = $Body -join "`n"

# Send email
Send-MailMessage -From $From -To $To -Subject $Subject -Body $Body -SmtpServer $SMTPServer
