Open VMRC console to 5vms per ‘hit enter’

$si = get-view serviceinstance

$sc= $si.Content
$sm = get-view -id $sc.SessionManager

foreach ($v in $vms) {

Searching for VMs with active questions.

for exmaple:
$vms = get-view -viewtype virtualmachine
$vms | ?{$_.runtime.question} | select name

In order to answer
assuming there is 1 question:
($vms | ?{$_.runtime.question}) | %{$_.AnswerVM($_.runtime.question.Id,’0′)}
Where 0 is for Retry because :
PowerCLI C:\> ($vms | ?{$_.runtime.question})[0].runtime.question.Choice.ChoiceInfo

Key : 0
Label : Retry
Summary : Retry

Key : 1
Label : Cancel
Summary : Cancel

So we can answer the question now with:

($vms | ?{$_.runtime.question}) | %{$_.AnswerVM($_.runtime.question.Id,’0′)}

Get-VMHostPnicCDP for check CDP/LLDP information for ESXi hostsystem physical nic.

Today i had to check some data in CDP, hence i wrote this script. I think it’s well documented, so it does not need description from my side. One thing to note, is that i have not checked if it prints out properly lldp information if you are using -lldp switch, i just assumed it’s going to be ok, looking at the vsphere documentation for this lldpinfo object.

		Gets CDP/LLDP information for ESXi physical nic.

		Gets CDP/LLDP information for ESXi physical nic.

		VMHost Can be piped to this function, it can VMHost object from get-vmhost or it get be HostSystme object from Get-View.

		This is the physical nic adapter name, for example: vmnic0 , it supports array as well: vmnic0,vmnic2,vmnicN.

		If paramenter -lldp was give, it will output content of lldpinfo from QueryNetworkHint method.

		PS C:\> Get-VMHostPnicCDP   -pnic vmnic0 -VMHost 'esxi1.local.lan'
		Without passing through pipeline it acceppts 1 vmhost only.

		PS C:\> Get-VMHostPnicCDP  -VMHost 'esxi1.local.lan'
		When -pnic parameter is skipped, CDP will be retrieved for all pnics in ESXi.

		PS C:\> 'esxi1.local.lan','esxi2' | Get-VMHostPnicCDP   -pnic vmnic0
		You can pass multiple VMHost names through pipeline

		PS C:\> get-vmhost -name 'esxi1.local.lan' | Get-VMHostPnicCDP -pnic vmnic1
		You can pass object directly from get-vmhost

		PS C:\>  get-view -viewtype hostsystem -filter @{'name'='esxi1.local.lan'} | Get-VMHostPnicCDP -pnic vmnic1
		You can pass object directly from get-view

How to get a list of hard disks in ESXi host system ?

That’s the only way so far i have figured out how to do it. Getting the information through CIM.

$esxi = 'myhost'
$CIMOpt = New-CimSessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck -Encoding Utf8 –UseSsl
$Session = New-CimSession -Authentication Basic -Credential $cred -ComputerName $esxi -port 443 -SessionOption $CIMOpt
Get-CimInstance -CimSession $Session -Namespace 'root/cimv2' -ClassName 'CIM_StorageExtent' | ?{$_.CreationClassName -eq 'HPVC_SAStorageExtent'} | Select PSComputerName, Caption, ElementName

In return i get this:

PSComputerName Caption ElementName
-------------- ------- -----------
esxi01.local.lan Disk 1 on HPSA1 Disk 1 on HPSA1 : Port 1I Box 1 Bay 1 : 136GB : Data Disk
esxi02.local.lan Disk 2 on HPSA1 Disk 2 on HPSA1 : Port 1I Box 1 Bay 2 : 136GB : Data Disk

This will work only for HP in this version as i am filtering output with HPVC_SAStorageExtent
Well, better this than nothing 😉

Get-gEvents for getting vsphere events with some additional filtering

Some time ago i wrote a dirty function that utilizes eventfilterspec to filter out events. I knew it had one flaw, because as far as i remember i was using there QueryEvents method. Nothing bad with that, but as far as i understand it will only return up to 1000 records. So i have finally modified it so it uses EventCollector. It has support for searching by eventchainID, eventTypeId, username, date. I have tried to document function as much as possible. For me it works ok. There is some tiny support for checking eventTypeIds inside the function. If something is not clear make sure you will read the help
get-help get-gEvents -full
One confusing bit might be that while passing the entityname , you have to pass the viewtype as well. Well i did it because i use it this way 😉 So i use Get-View -ViewType [type] -Filter @{‘name’=XXX’}
So it’s up to you what exactly you are looking for, while specifying the entity, In filter name will be put, but ViewType specifies the type of object, whether it will be a datacenter, vm , cluster, datastore etc..
I tried to implement the switch for enabling/disabling full formatted message, but for some reason it was not working, no idea why.

Quick examples:

How to check how many vmotions DRS has performed inside a particular cluster ?

(Get-gEvents -StartDate (get-date).AddDays(-1) -types 'VmBeingHotMigratedEvent' -EntityName 'Cluster_name' -ViewType ClusterComputeResource).Count

How to check how many vmotions DRS has performed inside a particular datacenter ?

(Get-gEvents -StartDate (get-date).AddDays(-1) -types 'VmBeingHotMigratedEvent' -EntityName 'Datacenter_name' -ViewType Datacenter).count

Endless possibilities basically.. i will throw 1 more
How many times user X has powered off a VM in last 7 days

(Get-gEvents -StartDate (get-date).AddDays(-7) -EventTypeIds 'VmPoweredOffEvent' -EventUsername 'DOMAIN\UserX' -systemUser:$false ).count

How many were there vmotions in some cluster during last 7 days

Get-gEvents -StartDate (get-date).AddDays(-7) -EventTypeIds 'VmFailedMigrateEvent' -EntityName 'SomeCluster' -ViewType ClusterComputeResource}

What if you want to check for other dates ? Use: -StartDate with (get-date).AddDays(-7) for example, to go 7 days back. Same goes for end date, -EndDate (get-date…..

When you will be giving parameter for the Entity, you can still use the -Recursion parameter with it to control whether you want to inspect only THAT entity, or its children, or both.

If you will skip -startdate or -enddate make sure you know that function is setting those variable up anyway with default values of: Enddate -> NOW , -startdate 7 days ago.

Make sure you know that by default if you will skip those parameters : systemuser and recursion will be set to true and all . So if you wonder how come you received system events if you were looking for user’s events, mark the -systemuser:$false , if you want to look only for event on entity and do not want to step inside its children use -recursion ‘self’ , because by default i set it to ‘all’.

You do not need to provide entity for this function to start, if not given it searches through everything.


function Get-gEvents
  <# .SYNOPSIS Get-gEvents is utilizing EventCollector to get information about events. .DESCRIPTION Get-gEvents utilizies most of what EventCollector has to offer. If Start or End date is not specified, the default values of: End - Now, Start - last 7 days will be applied. If you are using EventUserName parameter, you can then choose SystemUser parameter. By default it is selected as True, so if you do not want to see system events please set it to -SystemUser:$false , so you will get only user's records. This function also allows to get current list of types for events, if you do not remember a particular event, first try this function with -ListMainEVTypes From there you can use -ListSecEVTypes with -SubEVType and give it value of name of typse from previous command. .EXAMPLE Count DRS vmotions in Virtual Center for last day. (Get-gEvents -StartDate (get-date).AddDays(-1) -EventTypeIds 'VmBeingHotMigratedEvent').count .EXAMPLE Get-gEvents -ListSecEVTypes -SubEVType 'VmEvent' .PARAMETER ListMainEVTypes If used , you will received main event types categories. .PARAMETER ListSecEVTypes If used, you have to use SuvEVType to select the right subcategory to expand. .PARAMETER SubEVType From output of -ListMainEVTypes you can paste its name to -SubEVType , in response you will get more detailed event types. for example -SubEVType 'VmEvent' .PARAMETER eventChainId If you are interested only in particular event chain you can specify it's id here. .PARAMETER EventUsername You can search only user's events by giving in this parameter the login of user for example: 'userX', 'DOMAIN\UserX' .PARAMETER EntityName Name of the entity for which or underwhich you will be looking for events. It works together with ViewType. .PARAMETER systemUser In use with EventUsername, By default systemUser is $True, so that you will see the user's and the system events. If you will give -systemUser:$false then, only user's events will be gathered. .PARAMETER EventTypeIds This parameters can handle multiple ids of eventtypes separated by comas, for example : VmBeingHotMigratedEvent for checking drs migrations or VmPoweredOffEvent for vms getting powered off. If you do not know the specific type id, you can always run this function with ListMainEVTypes and ListSecEVTypes paramegters to get hints. .PARAMETER category Possible categories are: info, warning, error, user. .PARAMETER StartDate Start date for the search query. For example (get-date) for now, or (get-date).AddDays(-1) for yesterday. .PARAMETER EndDate End date for the search query. For example (get-date) for now, or (get-date).AddDays(-1) for yesterday. .PARAMETER Recursion You can choose from Self,Children,All options. Self is only checking events on Entity itself, Childred only on Children entities, and all is Self+Children. .PARAMETER ViewType This is the ViewType that you would normally use within Get-View to find that particular entity. For example HostSystem for host, or VirtualMachine for VM, or ClusterComputeResource for Cluster. .LINK .NOTES Author : Grzegorz Kulikowski #>
