Report Generation of VMs

[Sivaramsharmar]

Hi All,

Currently we are trying to generating report on VMs allocation with respect to Teams.

Each VM will be having a custom attribute as Team and corresponding team name is entered.

In below example I am illustrating the set of VMs belongs to 3 Teams.

Team: X

Setab01

Setab02

Setab03

Setab04

Team: Y

Setcd01

Setcd02

Setcd03

Team: Z

Setef01

Setef02

Team: X

Setgh01

Setgh02

Sample Output Needed:

Team                      Number of Sets               Number of VMs

--------                     ----------------------              ----------------------

X                                       2                                        6

Y                                       1                                        3

Z                                       1                                        2

Below script is returning only VM Set with respect to Number of VMs of each set

$vmnames = Get-VM

$vmname = $vmnames.name.substring(0,5) | Group-Object  | select Name,Count

$vmad = @()

foreach($v in $vmname){

    $vmcount = $v.count

    $vmd = "" | select "VM Set","VMs Count"

    $vmd."VM Name" = $v.name

    $vmd."VMs Count" = $vmcount

    $vmad += $vmd

}

$vmad

Ex: Output

VM Set                     VMs Count

-----------                    ----------------------

Setab                                   4

Setcd                                   3

Setef                                    2

Setgh                                   2

I am not able to get the desired output, Could some one help me.

Would something like this work for you?

$vmad = @()

Get-VM |

Group-Object -Property {(Get-Annotation -CustomAttribute Team -Entity $_).Value} | %{

    $row = '' | Select Team,'VM Sets','VM Count'

    $row.Team = $_.Name

    $row.'VM Count' = $_.Group.Count

    $row.'VM Sets' = ($_.Group | Group-Object -Property {$_.Name.substring(0,5)}).Count

    $vmad += $row

}

$vmad

Thanks Lucd,

Script is working fine.

We got additional requirement to add 3 more columns in the same script

Could you please help us to get the desired output.

If the VMs count in each Set is equal to 1 then it should be nominated under E

If the VMs count in each set is equal to 2 and less than 5 then it should be nominated under S

If the VMs count in each Set is equal to 9 and above then it should be nominated under I

Team: X

Setab01

Setab02

Setab03

Setab04

Setab05

Setab06

Setab07

Setab08

Setab09

Team: Y

Setcd01

Setcd02

Setcd03

Team: Z

Setef01

Setef02

Team: X

Setgh01

Setgh02

Sample Output:

Team                           I                                   S                             E                        Total VMs Count

---------                        ---                                -----                          ----                       ------------------------

    X                              1                                  1                             0                                       10

    Y                              0                                  1                             0                                        3

    Z                              0                                   1                             0                                        2

I'm afraid that is not clear to me.

What happens for example when a Team has 3 sets, with these sets having 1,3 and 11 VMs?

[Sivaramsharmar]

1 set is having 1 VM so it has to be nominated under E ( VM Count is 1 for this set)

1 set is having 3 VMs so it has to be nominated under S ( VM Count is 3 which is greater than 2 and less than 5)

1 set is having 11 VMs so it has to be nominated under I ( VM Count is 11 which is greater than 9)

[LucD]

So you don't need to see the number of sets anymore in the report?

[Sivaramsharmar]

Yes Lucd,

Instead of Number of sets, it is spanned as I , S & E as column labels used for individual sets with respect to VM Count

[LucD]

Like this?

Note that you will be missing sets with 6 to 8 VMs.

vmad = @()

Get-VM |

Group-Object -Property {(Get-Annotation -CustomAttribute Team -Entity $_).Value} | %{

    $obj = New-Object PSObject -Property @{

        Team = $_.Name

        'VM Count' = $_.Group.Count

        E = 0

        S = 0

        I = 0

    }

    $_.Group | Group-Object -Property {$_.Name.substring(0,5)} | %{

        if($_.Group.Count -eq 1){

            $obj.E += 1

        }

        elseif($_.Group.Count -lt 5){

            $obj.S += 1

        }

        elseif($_.Group.Count -ge 9){

            $obj.I += 1

        }

    }

    $vmad += $obj

}

$vmad

Hi Lucd,

In script '}'  is missing, I have added it.

Output of the Script is below.

Count                Name                           Group

--------               ---------                           ---------

Name is listing null in the report

But I am expecting Output in below format.

Team                           I                                   S                             E                        Total VMs Count

---------                        ---                                -----                          ----                       ------------------------

    X                              1                                  1                             0                                       10

    Y                              0                                  1                             0                                        3

    Z                              0                                   1                             0                                        2

Oops, yes, there was a typo.

I corrected the code above, can you try it again?
