New Technical White Paper - PowerShell Integration with VMware View 4.5/4.6

nospam@example.com (Eric Sloof) — Wed, 27 Apr 2011 21:38:55 +0200

Windows PowerShell is Microsoft’s command line shell and scripting language. PowerShell is built on the Microsoft .NET Framework and helps in system administration. By providing full access to COM (Component Object Model) and WMI (Windows Management Instrumentation), PowerShell enables administrators to perform administrative tasks on both local and remote Windows systems.

Administrators can manage the computers in the enterprise and perform administrative tasks from the command line using built-in cmdlets, which are specialized .NET classes. Unlike most other command line interfaces, PowerShell commands have been standardized using a verb-noun naming convention known as a cmdlet. This convention provides a clear description of the cmdlet, and enables access to different Windows components like the registry, file system, services, processes, and others. There are sufficient cmdlets to support most administrative activities.

VMware View PowerCLI cmdlets are provided by a dll, which is installed as part of the VMware View Connection Server (Server\bin\PowershellServiceCmdlets.dll) under the VMware Connection Server installation). This dll, once registered with PowerShell, allows all VMware View PowerCLI cmdlets to be run on the VMware Connection Server.

This technical paper covers the integration of VMware View with Windows PowerShell and PowerCLI.

New vSphere PowerCLI Cmdlet - Get-EsxTop

nospam@example.com (Eric Sloof) — Thu, 02 Dec 2010 22:13:50 +0100

With the latest release of PowerCLI (4.1.1) VMware has introduced a real cool new commandlet.

Get-EsxTop exposes esxtop functionality. The default parameter set is CounterValues. The Counter parameter filters the specified statistics. To retrieve all available counters, use the CounterInfo parameter set. The properties of each counter are returned through the Fields property (an array) of the CounterInfo output object. You can also retrieve stats topologies using the TopogyInfo parameter set. This information contains either inventory data that does not change or a counter instance structure describing the relationship between different counter instances.

vSphere 4.1 PowerCLI Administration Guide

nospam@example.com (Eric Sloof) — Fri, 01 Oct 2010 09:07:18 +0200

The vSphere PowerCLI Administration Guide provides information about using the VMware vSphere PowerCLI cmdlets set that ships with vSphere PowerCLI for managing, monitoring, automating, and handling life‐cycle operations for VMware vSphere components—virtual machines, datacenters, storage, networks, and so on.

It's is intended for anyone who needs to use vSphere PowerCLI. The information in the PDF is written for administrators who are familiar with virtual machine technology and Windows PowerShell.

There are two categories of users for vSphere PowerCLI: Basic administrators can use PowerShell commands included in vSphere PowerCLI to manage their VMware infrastructure from the command line and Advanced administrators can develop PowerShell scripts that may be reused by other administrators or integrated into other applications.

The vEcoShell is out of beta

nospam@example.com (Eric Sloof) — Fri, 04 Jun 2010 08:30:00 +0200

Scott Herold is happy to announce the release of the vEcoShell 1.2.6. It’s out of beta and officially has been deemed as a stable release. The list of features is quite limited, but the biggest change is multi session management which makes copying and pasting from the web and PS1 files possible. Under the hood every single script in the function library was re-written from scratch. Scott also has transferred the community homepage of The vEcoShell Initiative to Vizioncore’s vCommunity.

What's New with 1.2.6?

•Completely rewritten PowerPack to support VMware PowerCLU 4.0 Update 1 and its ability to manage connections to multiple $viServer objects.
•Ability to copy and paste code from "PowerShell Code" tab directly into standalone PS1 files (Will still need to Add-PSSnapin and Connect-VIServer for script to function).
•Ability to copy and paste code snippets from the internet and they will work without needing to add the $managedHost.connection code everywhere.

Download the latest version of vEcoShell and additional PowerPacks here.

Scott Herold about the GA: I am happy to announce that the 1.2.6 version of vEcoShell is now available on the Downloads Page. This update brings us into full compatibility with VMware PowerCLI 4.0 U1. In addition, we have decided to remove the product from beta and have provided our first stable release , which has been rigourously tested by the Vizioncore QC team. vEcoShell will remain Freeware, and continue to have a community support policy. The major difference in 1.2.6 is in how connections to multiple vCenter or ESX Servers are managed. In previous versions, vEcoShell maintained all session management and required custom code in nearly all of it's scripts to function properly. These scripts could not run externally to vEcoShell, so the PowerShell Code tab provided limited value. With the 1.2.6 release, vEcoShell now lets PowerCLI manage all connections. This means we were able to remove all custom code from our script library. Nearly every script that is in vEcoShell today can be run externally. Simply copy a code block from the "PowerShell Code"...

Arnim van Lieshout over at van-lieshout.com has created a great blog post with all the steps involved in completing the setup of the PowerCLI/The VESI environment:

1.Installation of Windows PowerShell
2.Installation of VMware PowerCLI
3.Installation of The Virtualization EcoShell

On April 8th we had a very good DutchVMUG meeting, which was totally dedicated to using PowerCLI and The VESI (Virtualization EcoShell Initiative). Although setting up the environment is straightforward, I wanted to do a small write-up which leads you through the install process and includes all download links needed.

PowerCLI Baseline-Compliancy Check

nospam@example.com (Eric Sloof) — Sat, 27 Mar 2010 16:38:00 +0100

My former colleague and virtualization friend Harold Schoofs has send me a real cool PowerShell script for automating the reporting part of the vSphere VUM baseline compliancy. The Baseline-Compliancy.Ps1 PowerShell script can be used to check the compliancy of all ESX Hosts registered on a VMware vCenter server and match up to any baseline. It will generate 3 kinds of output Files:

1) One file with all hosts and their compliancy state
2) One file with all attached baselines found
3) One file for every attached baseline found with its content

You can get you copy of Harold’s script here: Baseline-Compliancy.ps1 If you have any questions or suggestions for improvements just send your Tweets to @Hharold.

How to access PowerCLI trough SSH

nospam@example.com (Eric Sloof) — Mon, 22 Mar 2010 10:56:36 +0100

There are a lot of automation tools available which are able to deploy and configure an ESX host but if you want to use PowerCLI for the finishing configuration part there was always a manual step involved. I’ve found a way to start a PowerShell script from the service console trough SSH. The only thing you have to do is install WinSSHD on one of your Windows servers, just execute the distributable that you downloaded from the Bitvise website and follow the process. As soon as the installer completes, you will have a working WinSSHD installation on your machine. No changes to the default configuration are necessary; you only need to start it. However, you might want restrict your users' access to those features that they actually need, which will improve security. If you are new to WinSSHD, it’s highly recommended that you first make sure that you can establish a working SSH connection before you change any settings on the server. If you cannot connect to WinSSHD using its default configuration, this is most likely due to a network or firewall problem that you will need to resolve before you are able to connect. In its default configuration, WinSSHD accepts connections on the well-known port number for SSH servers, 22.

I’ve recorded a Jing video (with audio) which demos the CPU-Ready PowerCLI script running on my vCenter server launched from one of my ESX host’s service console.

Hidden tool: vmware-vimdump

nospam@example.com (Eric Sloof) — Thu, 07 Jan 2010 21:56:48 +0100

While poking around in the service console, I’ve discovered another hidden pearl. It’s called vmware-vimdump. You’ll find it at /usr/lib/vmware/bin and you can execute it by typing ./vmware-vimdump. Before executing this command, configure your SSH client e.g. Putty to log printable output to a file.
After a second or 10 you’ll see the following output, followed by every property you can think of:

=~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2010.01.07 21:41:38 =~=~=~=~=~=~=~=~=~=~=~=
