在 VMware 集群中查找所有 RAM 膨胀或交换的虚拟机？

如果我查看 vSphere 集群或资源池并看到一定程度的内存膨胀或交换，我如何确定哪些虚拟机受到了影响？一旦找到它们，我就知道该怎么处理它们:)

在下面的示例中，资源池中有 65 台虚拟机。内存膨胀量略低于 32 GB。如何识别哪些虚拟机的内存部分膨胀或被交换？

在此处输入图片描述

答案1

Powercli 非常适合这样的事情：

获取虚拟机 | 其中 {$_.BalloonedMemory -ne '0'}

这里还有更多示例：

特别看看“带有膨胀和交换的虚拟机” http://www.getshifting.com/wiki/powerclinotes#resource_pools_with_ballooning_and_swapping

从上面的链接复制：

$myCol = @()
foreach($vm in (Get-View -ViewType VirtualMachine | Where-Object `
  {$_.Summary.QuickStats.BalloonedMemory -ne "0"})){
    $Details = "" | Select-Object VM, `
    SwappedMemory ,BalloonedMemory

    $Details.VM = $vm.Name
    $Details.SwappedMemory = $vm.Summary.QuickStats.SwappedMemory
    $Details.BalloonedMemory = $vm.Summary.QuickStats.BalloonedMemory

    $myCol += $Details
  }
$myCol

希望这会有一点点帮助。

抱歉，速度太快了，所以您可能想在此信息输出中进行其他排序，以及按资源（主机、数据存储、集群）分组，我对整个 vCenter 进行了运行。

#!/bin/env python
__author__ = 'dladner'

import os
import sys
import pysphere

from pysphere import VIServer, MORTypes
from pysphere.resources import VimService_services as VI

s = VIServer()
s.connect("vcenter_hostname_or_ip", "username", "password")
vmlist = s.get_registered_vms(status="poweredOn")
count = 0
for vmpath in vmlist:
    pm1 = s.get_performance_manager()
    vm = s.get_vm_by_path(vmpath)
    mor = vm._mor
    ballooned = pm1.get_entity_statistic(mor, 77)
    swapped = pm1.get_entity_statistic(mor, 61)
    count += 1
    print "VM Number %d is %s and Ballooned Memory Amount on this VM is : %s" % (count, vmpath, ballooned)
    print "VM Number %d is %s and Swapped Memory Amount on this VM is  : %s" % (count, vmpath, swapped)

print "NOTICE: This statistic refers to VMkernel swapping and not to guest OS swapping."
s.disconnect()

这将为您提供以下结果，您可以按您想要的方式进行修改和排序，从较高的膨胀/交换量到较低的膨胀/交换量（+需要将 KB 转换为 MB）

我确实修改了输出（替换主机名并按膨胀/交换分组）

如果您需要一些额外的帮助，我可以尝试在明天让它更加合理，因为今天已经很晚了。

干杯。

PS 不确定 API 中的 -1:kiloBytes 含义是什么。

答案3

这是对旧线程的非常晚的添加，但您可以使其更快，将其保持在管道中并避免每个循环。试试这个：

    get-vm | where{ $_.swappedmemory -ne '0'} | get-view | Select Name,@{Name="Swapped”;Expression={$_.summary.quickstats.swappedmemory}},@{Name="Ballooned";Expression={$_.summary.quickstats.balloonedmemory}}
