Function for getting report on annotation in VirtualCenter server clusters or particular cluster

I described one way of getting this report in earlier post. If you want to use it as a function… there you go 😉
You can always use get-help greg-get-annotations , if you are in powershell session and want to check the syntax etc..
Report will also include the normal notes section. I’ve tested it in some environments, for example it took 38 sec to complete it in VI where there was ~1500vms, including creation of the csv.

function greg-get-annotations {
<#
.DESCRIPTION
Greg-get-annotations function stores information about annotation fields for vms in given
cluster or in all clusters in VC. It stores the result in an arraylist $vms, you can either create
a csv report from this object or display it on screen
greg-get-annotations |export-csv -NoTypeInformation c:\file1.csv will export it to csv file etc...
greg-get-annotations |format-table VMname,Cluster,CreatedOn,Notes will just display on screen a table with
annotations that include : vm name, its cluster and field "CreatedOn" and Notes

.PARAMETER clustername
Specifies the clustername against wchi report will be built

.EXAMPLE
greg-get-annotations -clustername 'cluster01'|Export-Csv c:\annotation-report.csv
Will procude report on vms that resides in 'cluster01' and store it in csv file

.EXAMPLE
greg-get-annotations -clustername 'cluster01'|ft *
Will procude report on vms that resides in 'cluster01' output it to screen

.EXAMPLE
greg-get-annotations |Export-Csv c:\annotation-report.csv
Will procude report on vms that resides in all clusters and output it to screen

.EXAMPLE
greg-get-annotations
Without specified -clustername switch, it will do report regarding all clusters in VC

Custom report, checking notes/description for vm, Active Directory description, ManagedBy, Operating System and exporting to csv

This time i wanted to build a report to check which vms are missing the notes/description section. If you have large virtual infrastructure it is very handy to have information about vm, what is its role. In case i don’t have notes/description field in VM, i would go to AD and check if the object has description. I would also like to know who to contact in case it does not have the description i will put data from ManagedBy field in AD. I would also like to know what operating system the vm has, and if it is powered on or off. At the end, i want to have a csv file with this information, so i can quickly edit it in Excel, or other spreadsheet sotware, apply some filters, conditional formatting and so on. It could be done also via powershell using the excel object for instance, and generating data directly to excel spreadsheet but it would take more time to write this at this point for me than applying filters and conditional formatting(1 minute).

$(foreach ($cluster in get-cluster) { get-view -viewtype VirtualMachine -SearchRoot $cluster.id | select @{N="VM name";E={$_.Name} },@{N=
"PowerState";E={$_.Summary.Runtime.PowerState}} ,@{N="Guest OS";E={$_.Config.GuestFullName} } , @{N="Cluster";E={$cluster.name} },@{N="VM .Notes";E={$_.Summary.
Config.Annotation} }, @{N="AD Description";E={(Get-QADComputer $_.Name).Description} },@{N="AD ManagedBy";E={((Get-QADComputer $_.name).ManagedBy | Get-QADUser)
.DisplayName} } }) | export-csv -NoTypeInformation c:\report.csv

I am pulling data cluster after cluster:
foreach ($cluster in get-cluster)
Pulling data for virtual machines in that particular cluster:
get-view -viewtype VirtualMachine -SearchRoot $cluster.id
Building custom colums :
select @{N=”VM name”;E={$_.Name} -> this should be self explanatory, at this moment i am in a loop where i am receiving vms for cluster, so $_ is the view for VM, $_.Name is the name field in the vm view
I want to have in report the powerstate information :
@{N="PowerState";E={$_.Summary.Runtime.PowerState}}
I want to have information about the operating system:
@{N="Guest OS";E={$_.Config.GuestFullName} }
Information about in which cluster vm resides :
@{N="Cluster";E={$cluster.name} }
Finally i want to see if the notes have been filled out or not:
@{N="VM .Notes";E={$_.Summary.Config.Annotation} }

In case the notes section is not filled out, i want to see what’s in AD description field:
@{N="AD Description";E={(Get-QADComputer $_.Name).Description} }
If that description would be empty i would like to know who to contact in order to get this information so:
@{N="AD ManagedBy";E={((Get-QADComputer $_.name).ManagedBy | Get-QADUser).DisplayName} }
At the end i close whole output $() in sub-expression to pipe it to export-csv

I was using here Quest cmdlets to query AD. You can download it for free at
http://www.quest.com/powershell/activeroles-server.aspx
Make sure that if you are using them in a script you will add them first by using this:
Add-PSSnapin Quest.ActiveRoles.ADManagement
