PowerShell实现数据中心能耗优化

function Get-EnergyConsumption {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory=$true)]
        [string]$ServerName
    )

    $cpuUsage = (Get-Counter -ComputerName $ServerName '\Processor(_Total)\% Processor Time').CounterSamples.CookedValue
    $memoryUsage = (Get-Counter -ComputerName $ServerName '\Memory\Available MBytes').CounterSamples.CookedValue
    
    # 计算能耗估算（基于Intel Xeon处理器能效模型）
    $energyCost = [math]::Round(($cpuUsage * 0.7) + ($memoryUsage * 0.05), 2)

    [PSCustomObject]@{
        ServerName = $ServerName
        Timestamp = (Get-Date).ToString('yyyy-MM-dd HH:mm:ss')
        CPUUsage = "$cpuUsage%"
        MemoryAvailable = "${memoryUsage}MB"
        EstimatedPower = "${energyCost}W"
        OptimizationSuggestion = if ($cpuUsage -lt 30) {'建议启用节能模式'} else {'建议优化负载分配'}
    }
}

# 监控服务器集群
'SRV01','SRV02','SRV03' | ForEach-Object {
    Get-EnergyConsumption -ServerName $_ -Verbose
} | Export-Csv -Path "Energy_Report_$(Get-Date -Format yyyyMMdd).csv"

核心功能：

1. 实时监控服务器CPU/内存使用率
2. 基于能效模型估算功耗
3. 生成节能优化建议

扩展方向：

• 集成IPMI接口获取实际功耗
• 添加自动电源模式调整功能
• 与Kubernetes集成实现智能调度
