VMware vSphere Health Check Report v4.0.0 by @lamw

Duncan Epping · Mar 19, 2010 ·

William Lam just released version 4 of his Health Check Report. I guess I can talk about it for hours but the sample report that William provides says more in just a few clicks than I can in 1000 words. Below you can find an outtake from the release notes. I clipped it as it was too long, but you can find the complete info here. Make sure this script is part of your standard toolkit as it will most definitely come in handy! Highly recommended.

This script generates a health check report similar to that of vmwareHealthCheckScript but for the new vSphere release of VMware ESX(i) 4.x and VMware vCenter 4.x and it’s managed entities. User’s can now fully customize the report based on the categories that are of importance to their operating environment, including selecting specific set of ESX(i) hosts and/or Virtual Machines.

The script reports on the following:

  • New Report is now completely modular in which categories to display via a configuration file
  • New Ability to specify specific ESX/ESXi host to query
  • New Ability to specify specific Virtual Mchines to query
  • New vCenter HA Advanced Runtime information
  • New vCenter HA Configuration (primary/secondary and node states)
  • New vCenter HA Advanced Configurations
  • New vCenter DRS Advanced Runtime information
  • New ESX/ESXi IP/HOSTNAME of vCenter Management IP
  • New ESX/ESXi Newly improved Hardware and System Health Stuats information
  • New ESX/ESXi Advanced Configurations
  • New ESX/ESXi NUMA information
  • New VM UUID,Bootime,Resource Statistics, Fault Tolerance, Thin provisioned and NPIV information
  • Win an Apple iPad for you and your friends!

The goal of the ScriptoMania contest is to help our wider community adopt ESXi by providing useful, fun and powerful scripts to manage the ESXi platform. The best part is that we give our winners bragging rights and we put some hard cold cash in your pockets. Are you up to the challenge?

    Contest Overview:

    vSphere Quick Start Guide – PowerCLI and PDF

    Duncan Epping · Jan 10, 2010 ·

    Alan Renouf posted an article on the vSphere Quick Start Guide we recently wrote which triggered this article. First let me quote from Alan’s article:

    I was responsible for adding all the PowerCLI throughout the book, basically if something is explained and there is an easy way to do it in PowerCLI, we have added a code reference, this enables you to see how much is covered by PowerCLI and also how easy it actually is.

    In writing the PowerCLI areas I didn’t actually realise how many we had put in until the book was completed and I extracted them all into a nice zip file which can be downloaded and used from here: http://www.yellow-bricks.com/wp-content/uploads/quickstartguide.zip

    All in all there are 67 scripts, now obviously if you want to know more information about these scripts and exactly where they fit in you will need to buy the book.

    Download these scripts as they will definitely help you manage your environment better and more consistent. Secondly they will help you learn Powershell/PowerCLI faster, especially if you also own the book. Which is the second part of this post, the book… it’s available in print via Amazon and Lulu. But also available as a PDF via Lulu. You can find the links below, but keep in mind that depending on shipping costs sometimes the US one might be cheaper. Let me also be crystal clear about the PDF, it’s a separate item. If you want the PDF you will need to order it. We do however have added it to our “must haves” for the next book, we hope we will be able to offer a printed and pdf version in one package by then.

    Anyway, close to 2000 copies have been sold by now. Amazon has books on stock which should make a fast delivery possible.

    Amazon – US $15.99
    Lulu – Europe: € 14.29
    Lulu – PDF: €7.14 / $9.99

    vscsiStats output in esxtop format?

    Duncan Epping · Dec 17, 2009 ·

    This week we(Frank Denneman and I) played around with vscsiStats, it’s a weird command and hard to get used to when you normally dive into esxtop when there are performance issues. While asking around for more info on the metrics and values someone emailed us nfstop. I assumed it was NDA or at least not suitable for publication yet  but William Lam pointed me to a topic on the VMTN Communities which contains this great script. Definitely worth checking out. This tool parses the vscsiStats output into an esxtop format. Below a screenshot of what that looks like:

    Book: VMware VI and vSphere SDK

    Duncan Epping · Dec 13, 2009 ·

    I received Steve Jin’s book VMware VI and vSphere SDK: Managing the VMware Infrastructure and vSphere two weeks ago. For those who don’t know Steve, he is the man behind the VI and vSphere Java API which can be found here. But that’s not the topic today, the topic is the book Steve recently published. The book is available via Amazon and most other large (online) bookstores.

    VMware VI and vSphere SDK takes you on a tour through the SDK trenches. Knowing the SDK is essential when scripting or programming with for instance Powershell, Perl, Java and Python.

    I am not a developer and always had a tough time understanding the structure and getting my head wrapped around the “managed objects” and “data objects” concepts. Steve managed to get me on the track. I’m half way through the book right now and can already highly recommend it to everyone who wants to know more about the SDK, everyone who recently started scripted and is running into limitations of provided examples, and everyone who wants to know more about the core of vSphere / VI3.

    One of the Amazon reviews that stood out to me is the following by David Rousseau:

    If like me you are tired of using vSphere or VI 2.5 official SDK, this book is for you.

    Steve Jin has done a great job simplifying SDK access and improving performance drastically.
    After using his VI Java API described in this book, you will no longer return to official VI Java SDK or other VI Toolkit.

    You can code in Java but also in Python using Jython or IronPython.

    We’ve choosed Jython and coupled it with some great web frameworks in python like Django. We’ve built a powerful web app exposing a RESTful API.

    Add to this a real talent in popularizing VI objects in the SDK, this book saved me lots of time.
