如何同时查看多台ESXI主机的资源使用情况的方法

问题疑问：虽然Vcenter控制台默认可以看到ESXI主机当前的内存和CPU使用情况,但是需要每一台主机都点击查看,假如主机数量较多的时候,手工效率很低。

解决方法：下列脚本可以收集vcenter下所有主机的CPU内存使用百分比。按照实际情况填写IP地址、用户名、密码即可,收集结果会以日期为命名保存在当前目录下：

$ipaddress=
$username=
$passwd=
Write-host "Script Running now , please waiting it.." -ForegroundColor Green
$erroractionpreference = SilentlyContinue
$Infolist = @()
$Today=(get-date).tostring("yyyyMMdd")+"VMwareInfo"
Write-host "Loading VMware Module...." -ForegroundColor Green
ASNP VMware.Vimautomation.Core
Write-host "Login Vcenter...." -ForegroundColor Green
Connect-VIServer $ipaddress -User $username -Password $passwd
Write-host "Collecting Infomation...." -ForegroundColor Green
$esxihost=(Get-VMHost | % { $_.Name })
foreach($n in $esxihost)
{
$cpuused=$(Get-VMHost $n.TrimEnd()).CpuUsageMhz
$cputotal=$(Get-VMHost $n.TrimEnd()).CpuTotalMhz
$cpupercent = ($cpuused * 100.0)/$cputotal
$cpupercent = "{0:N1}" -f $cpupercent
$memused=$(Get-VMHost $n.TrimEnd()).MemoryUsageGB
$memtotal=$(Get-VMHost $n.TrimEnd()).MemoryTotalGB
$mempercent = ($memused * 100.0)/$memtotal
$mempercent = "{0:N1}" -f $mempercent
$Info = New-Object PSObject
$Info | Add-Member NoteProperty -Name Name -Value $n.TrimEnd()
$Info | Add-Member NoteProperty -Name CPU % -Value $cpupercent
$Info | Add-Member NoteProperty -Name Mem % -Value $mempercent
$Infolist+=$Info
}
$Infolist | Export-csv -NoTypeInformation -Encoding UTF8 "$Today.csv"
Write-host "Finish !" -ForegroundColor Green
cmd /c "pause"
exit
