I’m excited to highlight that VMware, specifically Chethan Kumar, has released an updated Performance Troubleshooting guide for vSphere. The document was originally penned by Hal Rosenberg and has been referred to as the ‘Performance Troubleshooting Bible.’ Both of these fine gentleman work as performance engineers within VMware and have strove to identify common issues and potential resolutions in an easy-to-use framework.
This new edition has been updated specifically for vSphere 4.1 and should be part of every virtual administrators core collection. Whatever you call it, all virtual administrators should not only review this guide for the cool performance information contained within, but it should be used as Step #1 for troubleshooting any performance related issue. Using it will help you diagnose all the most common issues seen in the field.
Abstract:
This document provides step-by-step approach for troubleshooting most common performance problems in vSphere-based virtual environments. The steps discussed in the document use performance data and charts readily available in the vSphere Client and esxtop to aid the troubleshooting flows. Each performance troubleshooting flow has two parts:
- How to identify the problem using specific performance counters.
- Possible causes of the problem and solutions to solve it.
I reference this guide at the end of all my presentations and will be updating my links to the new edition. Performance is often seen as a dark art but in reality is often misunderstood. I hope resources, like this guide, will help take everyone’s knowledge to the next level through awareness and practical application.
The document is available here: Troubleshooting Performance Related Problems in vSphere 4.1 Environments
