How to count the number of virtual machines that are turned on.

Try to learn this PowerShell stuff... oh what fun.

Given that maintenance mode does not work unless you manually VMotion servers or stop them, I am trying to program a loop to make sure that all VM on the host is disabled.

How can I get the value of "#PoweredOn" in this statement so that I can compare it? I want to leave the loop when the number of virtual machines under voltage = 0.

function shutdownGuests()

{

Get-VMHost HOST1. Get - VM | Stop-VMGuest

$num_powered_on = $null

{}

Write-Host $num_powered_on

Write-Host $PoweredOn

$num_powered_on = get-VMHost HOST1. Select-Object Name, @{Name = "#PoweredOn"; Expression = {($_ |)} Get - VM | Where-Object {$_.} PowerState - eq "Receptor"} | Measure-Object). {{Count}}

Start-Sleep - seconds 10

} While that ($num_powered_on & gt; 0)

#Loop and check to see if all VMs are closed, and then return to main()

}

Try something like this:

while (get-vmhost XXX | get-vm | where { $_.PowerState -ne "PoweredOff" }) {
    # Wait a while
}

  • VMware View | PowerCLI | How to get the number of virtual machine in a specific pool-ID

    Hello

    Generally, to get the number of VMS in a pool, I run this command:

    Get-pool | Select Pool_id, @{Name = "NumVM"; Expression = {($_ |)} (Get - DesktopVM). County}} | out-gridview

    But how can I list all the pools and then select the pool I want a county of?

    Maybe something like:

    Select 1 for accounts

    Select 2 for Marketing

    and then County VM just for this pool and immediate where at the output (Out-gridview or Export-CSV)

    Thanks, Julien

    I don't understand the line:

    1.. $pools. County | %{
    Write-Host "$_" $Pools [$_ - 1]. Name

    Why do we need the 1...

    Also is the same as get-get-resourcepool pool?

    How can I get the counts for each parent in a single query

    Published by: user7955917 on August 24, 2012 07:26

    Generic function how you want the query to be.

    If the structure is known in advance, as in your example a 'books' and then a 'library' root element, it's as simple as:

    SQL> select x1.parent_id, x2.child_name, count(*)
      2  from tmp_xml t
      3     , xmltable(
      4         '/books/bookstore'
      5         passing t.object_value
      6         columns parent_id   for ordinality
      7               , child_list  xmltype path '*'
      8       ) x1
      9     , xmltable(
     10         '/*'
     11         passing x1.child_list
     12         columns child_name varchar2(30) path 'name()'
     13       ) x2
     14  group by x1.parent_id, x2.child_name
     15  order by x1.parent_id, x2.child_name
     16  ;
    
     PARENT_ID CHILD_NAME                       COUNT(*)
    ---------- ------------------------------ ----------
             1 book1                                   2
             1 book2                                   1
             1 book4                                   1
             2 bookn                                   1
             2 bookn_1                                 1
             2 book1                                   1
             2 book2                                   1
             2 book3                                   2
             3 book1                                   1
             3 book2                                   1
    
    10 rows selected
     
    

    If you want a generic solution that works without knowledge of the structure, you will need a recursive approach, and most importantly, you should know which nodes in distinct, I suppose that the leafs?

    Also, please help if you can provide the link of reference on the function name() years what are the other expression, that I can use after the path

    You can start reading the documentation: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ

    The clause PATH expects a XQuery expression however before 11.2, we can put only simple XPath expressions.
