💙 PowerShell을 활용한 서버 자동화 및 모니터링 기초

// 1단계: 서버 연결 설정
$server = "localhost"
Invoke-Command -ComputerName $server -ScriptBlock {
    Get-Service | Where-Object { $_.Status -eq "Running" }
}

// 2단계: 디스크 공간 모니터링
$threshold = 80
Get-WmiObject -Class Win32_LogicalDisk | ForEach-Object {
    if ($_.FreeSpace / $_.Size * 100 -lt $threshold) {
        Write-Warning "경고: $($($_.Name)) 디스크 사용률 $($($_.FreeSpace / $_.Size * 100))%"
    }
}

// 3단계: 이벤트 로그 분석
Get-WinEvent -FilterHashtable @{Logname="System"; ProviderName="Microsoft-Windows-Eventlog"} | Where-Object {
    $_.TimeCreated -gt (Get-Date).AddDays(-1) -and 
    $_.LevelDisplayName -eq "Error"
} | Select-Object TimeCreated, Message

// 4단계: 자동 백업 스크립트
$backupPath = "C:\Backups\"
Get-ChildItem -Path C:\ | Where-Object { $_.PSIsContainer } | ForEach-Object {
    $folderName = $_.Name
    Compress-Archive -Path "$($_.FullName)\*" -DestinationPath ".\$folderName.zip"
    Move-Item -Path ".\$folderName.zip" -Destination $backupPath
}
