PowerCLI & Onyx
This document discusses VMware vSphere PowerCLI, a Windows PowerShell interface for managing VMware vSphere, and Project Onyx, which serves as a proxy between the vSphere Client and vCenter Server to monitor network communication and translate it into reusable PowerShell code. It provides an overview of PowerCLI functionality and resources, tips for efficiently working with PowerCLI such as reducing object name lookups, and a demonstration of how Onyx can be used to generate PowerShell code for automating vSphere tasks like creating scheduled tasks.

- 13. 13 It’s a fact:PowerCLI does cover the entire vSphereAPI ! PowerCLI introduces over 225 cmdlets and 170 automation objects •Designed to be fast and easy to use •vSphere API has close to 500 operations and over 2000 objects .Net toolkit expose the entire vSphereAPI •Client side .Net library distributed with PowerCLI •Could be used in .Net applications and Powershell scripts •Powershell interface – Get-View cmdlet Get started with .Net toolkit
- 14. 14 Retrieving views inPowerCLI Get-View – the entry point to the .Net toolkit View – static copy of a server side managed object
- 15. 15 Retrieving views inPowerCLI – performance impact # Retrieve views for several vms filtered by PowerState Get-VM | Where {$_.PowerState -eq "PoweredOn"} | Get-View VS Get-View -ViewType "VirtualMachine" ` -Filter @{"Runtime.PowerState" = "PoweredOn"} √
- 16. 16 # Interested onlyin few of the view properties? Get-View -ViewType “VirtualMachine” VS Get-View -ViewType “VirtualMachine” ` -Property “Name” , “Runtime.PowerState” √ Increase performance when retrieving view objects WOW ! Specifying property parameter is ~2000% faster on 100 vms
- 17. 17 MoRef - ManagedObject Reference Most API method invocations require MoRef as a parameter MoRefs made easier in PowerCLI 4.1 ! # Retrieve MoRef from the view object $vm = Get-VM “MyVm” $vmView = $vm | Get-View $_this = Get-View -Id ‘ScheduledTaskManager’ $_this.CreateScheduledTask($vmView.MoRef, $spec) # Using object’s Id where MoRef is needed $vm = Get-VM “MyVm” $_this = Get-View -Id ‘ScheduledTaskManager’ $_this.CreateScheduledTask($vm.Id, $spec)
