Preface

Retrieving statistic keys


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:
