VMware PowerCLi 使用示例

这几天研究PowerCLI，积累了几个例子，记下来，以便以后或者大家使用。部分例子来着网络，具体出处参考附录

1 获取vm 磁盘 和磁盘对应的datastore的信息

这个例子可以针对一台虚机有多个磁盘，但每个磁盘可能所属datastore不同，所以需要列出来查看

Get-VM | %{
    $_.HardDisks | Select @{N="VM";E={$_.Parent.Name}},
        Name,
        @{N="DS";E={$_.Filename.Split(']')[0].TrimStart('[')}}
}

如果分着取的话也可以直接转换为

$targetVM = Get-VM -Name "vmname"
$disks = Get-HardDisk $targetVM
$diskDatastore = $disks.Filename.Split(']')[0].TrimStart('[')

2 获取vm,cpu,memory,guest,vmdk,datastore信息，并保存为HTML文档，这里主要是HTML文档生成的语法

$a = "<title>$name</title>"
$a = $a +"<style>"
$a = $a + "BODY{background-color:blue;}"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$a = $a + "TH{border-width: 1px;padding: 1px;border-style: solid;border-color: black;background-color:thistle}"
$a = $a + "TD{border-width: 1px;padding: 1px;border-style: solid;border-color: black;background-color:PaleGoldenrod}"
$a = $a + "</style>"
 
foreach($cluster in Get-Cluster){
    foreach($rp in Get-ResourcePool -Location $cluster){
        $report = foreach($vm in (Get-VM -Location $rp)){
            Get-HardDisk -VM $vm |
            Select @{N='Cluster';E={$cluster.Name}},
                @{N='ResourcePool';E={$rp.Name}},
                @{N='VM';E={$vm.Name}},
                @{N='HD';E={$_.Name}},
                @{N='Datastore';E={($_.Filename.Split(']')[0]).TrimStart('[')}},
                @{N='Filename';E={($_.Filename.Split(' ')[1]).Split('/')[0]}},
                @{N='VMDK Path';E={$_.Filename}},
                @{N='Format';E={$_.StorageFormat}},
                @{N='Type';E={$_.DiskType}},
                @{N='CapacityGB';E={$_.CapacityGB}}
        }
        $report | ConvertTo-Html -Head $a | Out-File -FilePath "C:\temp\$($cluster.Name)-$($rp.Name)-report.html"
    }
}

样例如下：

Cluster	ResourcePool	VM	HD	Datastore	Filename	VMDK Path	Format	Type	CapacityGB
Cluster2	Resources	BPPM_Oracle	硬盘 1	NFS_Storage_OS_VOL3	BPPM_Oracle	[NFS_Storage_OS_VOL3] BPPM_Oracle/BPPM_Oracle-000001.vmdk	Thin	Flat	100
Cluster2	Resources	rcwin01	硬盘 1	VMRestoreVol	rcwin01	[VMRestoreVol] rcwin01/rcwin01.vmdk	Thin	Flat	100
Cluster2	Resources	install-test	硬盘 1	NFS_Storage_OS_VOL3	install-test	[NFS_Storage_OS_VOL3] install-test/install-test.vmdk	Thin	Flat	50
Cluster2	Resources	10.200.200.188	硬盘 1	NFS_Storage_OS_VOL3	10.200.200.188	[NFS_Storage_OS_VOL3] 10.200.200.188/10.200.200.188.vmdk	Thin	Flat	100
Cluster2	Resources	portal-db-test	硬盘 1	NFS_Storage_OS_VOL3	portal-db-test	[NFS_Storage_OS_VOL3] portal-db-test/portal-db-test.vmdk	Thin	Flat	100

3 根据datastoreid 来获取datastore的名字

这个例子后面get-view -property name 用法比较重要，power-cli有很多根据id来获取name的情况，基本都可以用这个例子来解决，避免直接获取name带来的性能问题

Get-VM -Location "可选-指定datacenter" -Name "可选-指定vm" | % { @{$_.Name=$_.DatastoreIDList | %{(Get-View -Property Name -Id $_).Name}} }

可以举一反三一下，比如根据aa，获取bb的信息

 

4 这个例子比较有趣，可以设置输出的的格式

下面的例子是通过一条命令，获取Host, Cluster and Datastore Details

具体大家可以看这位的参考Host, Cluster and Datastore Details

Is there any way to use autosize, as the long datastore names trunctes.

Try Autosize

Get-VM (Get-content c:\temp\vms.txt) | Select-Object -Property @{Name='VMName';Expression={$_.Name}},VMHost,@{Name='ClusterName';Expression={$_.VMHost.Parent}}, @{"Name"="Datastore"; expression={($_.DatastoreIDList | %{(Get-View -Property Name -Id $_).Name}) -join ", "}} | FT -AutoSize

 

Try wrapping?

Get-VM (Get-content c:\temp\vms.txt) | Select-Object -Property @{Name='VMName';Expression={$_.Name}},VMHost,@{Name='ClusterName';Expression={$_.VMHost.Parent}}, @{"Name"="Datastore"; expression={($_.DatastoreIDList | %{(Get-View -Property Name -Id $_).Name}) -join ", "}} | FT -Wrap

 

If possible, can we use sort-object with VM Names ?

Yep, just pipe to Sort-Object

Get-VM (Get-content c:\temp\vms.txt) | Select-Object -Property @{Name='VMName';Expression={$_.Name}},VMHost,@{Name='ClusterName';Expression={$_.VMHost.Parent}}, @{"Name"="Datastore"; expression={($_.DatastoreIDList | %{(Get-View -Property Name -Id $_).Name}) -join ", "}} | Sort VMName

Also, can we use export-csv to export the out put to excel ?

Yep, Just pipe to Export-CSV

 

Get-VM (Get-content c:\temp\vms.txt) | Select-Object -Property @{Name='VMName';Expression={$_.Name}},VMHost,@{Name='ClusterName';Expression={$_.VMHost.Parent}}, @{"Name"="Datastore"; expression={($_.DatastoreIDList | %{(Get-View -Property Name -Id $_).Name}) -join ", "}} | Export-CSV -NoTypeInformation C:\temp\VMExport.csv

5 一条命令获取Vmhost及其网络信息

To list all ESX Hosts and their Service console information

Get-VMHost | Get-VMHostNetwork | Select Hostname, ConsoleGateway, DNSAddress -ExpandProperty ConsoleNic | Select Hostname, PortGroupName, IP, SubnetMask, ConsoleGateway, DNSAddress, Devicename

获取的样例如下

HostName	PortGroupName	IP	SubnetMask	ConsoleGateway	DNS Address	DeviceName
esx01	SC	192.168.2.33	255.255.255.0	192.168.2.1	192.168.2.20 192.168.1.20	vswif0
esx01	SC 2	192.168.3.43	255.255.255.0	192.168.2.1	192.168.2.20 192.168.1.20	vswif1
esx02	SC	192.168.1.12	255.255.255.0	192.168.1.254	192.168.1.20	vswif0
esx03	SC	192.168.2.34	255.255.255.0	192.168.2.1	192.168.2.20 192.168.1.20	vswif0
esx03	SC 2	192.168.3.44	255.255.255.0	192.168.2.1	192.168.2.20 192.168.1.20	vswif1

To list all ESX Hosts and their VMotion Enabled Networks :

Get-VMHost | Get-VMHostNetwork | Select Hostname, VMkernelGateway -ExpandProperty VirtualNic | Where {$_.VMotionEnabled} | Select Hostname, PortGroupName, IP, SubnetMask, VMkernelGateway, Devicename

样例如下

HostName	PortGroupName	IP	SubnetMask	VMKernelGateway	DeviceName
esx01	VMkernel	192.168.3.33	255.255.255.0		vmk0
esx02	VMkernel	192.168.3.34	255.255.255.0	192.168.3.1	vmk0

当然标准的获取方式如下，获取了ESX的ip，和vmotionip

Get-VMHost * | Sort Name | Get-View | Select Name,@{N="Address";E={($_.Config.Network.Vnic | ? {$_.Device -eq "vmk0"}).Spec.Ip.IpAddress,($_.Config.Network.Vnic | ? {$_.Device -eq "vmk1"}).Spec.Ip.IpAddress}} )
" " | Out-file  C:\SMinfo\"HostIPandvMotionIP$(Get-Date -Format 'yyyyMMdd').txt" -append

6 如何提高查询的速度

有时候，我们可以按照规定，获取这些信息，但如果数据量特别大，脚本运行时间会很长，那如何更快速的减少联表查询，加快速度呢，下面是个好例子，这个涉及到哈希索引，哥就不懂了

Receving cluster name for vms fast.

7 获取vm name 和ip地址

Get-VM | Select Name, @{N="IP Address";E={@($_.guest.IPAddress[0])}}

以上是几个分着的例子，主要都侧重某个方面，实际要做到时候，还要再组合和调试，尤其对于初次接触powershell的人比较麻烦了，下面这个例子是我实际工作中结合别人例子改造的，供参考

8 获取vmname,vmid,ESXHOST,ESXIP,cluster,datastore,下面三个脚本功能差不多，只是速度不同，供参考

################如果不考虑性能的话，下面这个脚本比较简单易懂,但速度慢####################

@{N="ESXHOST";E={(Get-VMHost -VM $_).name}}, `
@{N="Cluster";E={Get-Cluster -VM $_}}, `
@{N="Datastore";E={Get-Datastore -VM $_}},`
Time | Export-Csv -NoTypeInformation c:\VMInfo\"33Export67VMinfo$(Get-Date -Format 'yyyyMMdd').csv"
Disconnect-VIServer -server * -force  -Confirm:$false

################考虑性能，尽量使用属性的方式获取，大概比上面节省五分之二的时间############
Connect-VIServer -server 10.200.108.67 -user [email protected] -password 密码
Get-VM | Select Name,id, `
@{Name=’ESXIP’;Expression={ &{$script:esx=get-view -Id $_.vmhostid -property name,config};($script:esx.Config.Network.Vnic | where{$_.Device -eq 'vmk0'}).Spec.Ip.IpAddress }},`
vmhost, `

Time | Export-Csv -NoTypeInformation c:\VMInfo\"44Export67VMinfo$(Get-Date -Format 'yyyyMMdd').csv"
Disconnect-VIServer -server * -force  -Confirm:$false

#############添加了硬盘对应的datastore的信息，因为有些机器不同硬盘所属datastore不同##########

Connect-VIServer -server 10.200.108.67 -user [email protected] -password P@ssw0rd
Get-VM | Select Name,id, `
@{Name=’ESXIP’;Expression={ &{$script:esx=get-view -Id $_.vmhostid -property name,config};($script:esx.Config.Network.Vnic | where{$_.Device -eq 'vmk0'}).Spec.Ip.IpAddress }},`
vmhost, `
@{Name=’Cluster’;Expression={$_.VMHost.Parent}}, `
@{N="Storage";E={(Get-HardDisk -VM $_ |Select @{N='HD';E={$_.Name}},@{N='Datastore';E={`
 ($_.Filename.Split(']')[0]).TrimStart('[')}}) -replace "@{HD=","" -replace "; Datastore","" -replace "}","" -replace "{","" `
 }},`
 Time | Export-Csv -NoTypeInformation -encoding utf8 c:\VMInfo\"Export67VMinfo$(Get-Date -Format 'yyyyMMdd').csv" 
Disconnect-VIServer -server * -force  -Confirm:$false

##################如果想限定vm的范围，可以使用csv文件限定，减少查询#################
Connect-VIServer -server 10.200.108.67 -user [email protected] -password 密码
$vmname = Import-csv "C:\VMInfo\vmhosts.csv" 

$vmname | %{Get-VM $_.name| Select Name,id, `
@{Name=’ESXIP’;Expression={ &{$script:esx=get-view -Id $_.vmhostid -property name,config};($script:esx.Config.Network.Vnic | where{$_.Device -eq 'vmk0'}).Spec.Ip.IpAddress }},`
vmhost, `
@{Name=’Cluster’;Expression={$_.VMHost.Parent}}, `
<#@{N="Storage";E={(Get-HardDisk -VM $_ |Select @{N='HD';E={$_.Name}},@{N='Datastore';E={($_.Filename.Split(']')[0]).TrimStart('[')}}) -replace "@{HD=","" `
-replace "; Datastore","" -replace "}","" -replace "{","" `
 }},`#>

%{(Get-View -Property Name -Id $_).Name}) -join ", "}},`
 Time }| Export-Csv -NoTypeInformation -encoding utf8 c:\VMInfo\"Export67VMinfo$(Get-Date -Format 'yyyyMMdd').csv" 
Disconnect-VIServer -server * -force  -Confirm:$false
###########升级版，添加了过滤条件和ip的分隔符#########
Connect-VIServer -server 10.200.108.67 -user [email protected] -password P@ssw0rd
Get-VM |where{$_.PowerState -eq “PoweredOn”}| Select NAME, @{Name=’VMIP’;Expression={($_.Guest.IPAddress) -join ";"}},ID,`

 csv文件样例如下:

Name	Id	ESXIP	VMHost	Cluster	Storage	Time
install-test	VirtualMachine-vm-868	esx.vsphere.com.1	10.200.236.15	Cluster2	硬盘 1=NFS_Storage_OS_VOL3
clm-db-3	VirtualMachine-vm-735	esx.vsphere.com.2	10.200.236.16	Cluster2	硬盘 1=NFS_Storage_OS_VOL3 硬盘 2=NFS_Storage_OS_VOL3

9 获取ESX IP 的两种方法，一定要注意以下格式，当你通过get-vm获取其他属性信息时，下面的格式可供参考

#方法一比较慢
Get-VM | Select @{N="ESXip慢";E={((Get-VMHost -VM $_).ExtensionData.Config.Network.Vnic | ? {$_.Device -eq "vmk0"}).Spec.Ip.IpAddress}}
#方法二比较快
Get-VM | Select @{Name=’ESXIP’;Expression={ &{$script:esx=get-view -Id $_.vmhostid -property name,config};($script:esx.Config.Network.Vnic | where{$_.Device -eq 'vmk0'}).Spec.Ip.IpAddress }}

 10 如果想看语句执行到底耗时多久,进行统计等,可以使用如下命令

#统计耗时示例
vSphere PowerCLI> Measure-Command {get-vm}

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 1
Milliseconds      : 14
