查找VMware群集中所有具有激增或交换RAM的虚拟机吗?


11

如果要查看vSphere群集或资源池,并看到一定级别的内存膨胀或交换,如何确定受影响的VM?找到他们后,我知道该怎么办:)

在下面的示例中,资源池中有65个虚拟机。膨胀的RAM不足32 GB。如何确定哪些VM的部分RAM膨胀或交换?

如果您想简化代码,则这是一个单行代码:Get-View -ViewType VirtualMachine | 哪里对象{$ _。Summary.QuickStats.BalloonedMemory -ne“ 0”} | 选择@ {n ='ComputerName'; e = {$ _。name}},@ {n ='SwappedMemory'; e = {$$。Summary.quickstats.SwappedMemory}},@ {n ='BalloonedMemory'; e = {$
_。Summary.quickstats.SwappedMemory

Powercli非常适合这样的事情:

获取虚拟机| 其中{$ _。BalloonedMemory -ne'0'}

在此处加载更多示例:

特别要看一下“具有热气球交换功能的虚拟机” http://www.getshifting.com/wiki/powerclinotes#resource_pools_with_ballooning_and_swapping

从以上链接复制:

$myCol = @()
foreach($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

您可以粘贴代码!

这可以正常运行,在具有约1200个VM的Virtual Center上运行不到2分钟。问题已更新。

希望这会有所帮助。

抱歉,很快,所以您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,群集)分组,我遇到了整个vCenter。

#!/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()

这将为您提供下面的结果,您可以在其中进行修改并按所需的方式对其进行排序,从增加的数量/交换的金额降低到降低的数量(+希望将KB转换为MB)

我做了修改后的输出(替换的主机名,按气球号/交换分组)

如果您需要其他帮助,我可以尝试明天将其变得更加理智,因为今天已经很晚了。

PS不知道-1:kiloBytes从API意味着什么。


谢谢。让我连接起来,并在遇到麻烦的环境中尝试此操作。

我想知道是否有更快的方法来获取此信息。
ewwhite 2013年

是的,那很慢。
Danila Ladner 2013年

我很肯定有一种使它更快的方法,那只是一个笨拙的原型,我会研究一下。

@DanilaLadner,感谢您的回答。该脚本运行非常慢。有没有办法使它更快?

这是对旧线程的最新补充,但是您可以更快地将其保存在管道中,并避免每个循环使用a。试试看:

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