A statistic key identifies a vRealize Operations Manager metric. The Get-OMStatKey cmdlet retrieves vRealize Operations Manager statistic keys. The syntax of the Get-OMStatKey cmdlet is given here. The first parameter set is the default:

Get-OMStatKey [[-Name] <String[]>] [-ResourceKind 
    <String[]>] [-AdapterKind <String[]>] [-Server <OMServer[]>] 
    [<CommonParameters>]

The second parameter set is required to retrieve statistic keys by resource:

Get-OMStatKey [[-Name] <String[]>] -Resource 
    <OMResource[]> [-Server <OMServer[]>] [<CommonParameters>]

The -Resource parameter is required.

The Get-OMStatKey cmdlet without parameters returns all of the statistic keys. There are too many statistic keys to shows in this book. Piping the output of the Get-OMStatKey cmdlet to the Measure-Object cmdlet and displaying the Count property shows us the number of statistic keys, as in the following command:

PowerCLI C:> (Get-OMStatKey | Measure-Object).Count

In my lab environment, the output of the preceding command is as follows:

24078

To show you the properties of a statistics key object, we will retrieve the statistic keys, select only the first one, and format the output in a list view using the following command:

PowerCLI C:> Get-OMStatKey | Select-Object -First 1 | Format-List

The preceding command has the following output:
