VMware: Troubleshooting Performance vSphere 4.1 guide


VMware VROOM released/updated a nice Performance Troubleshoot guide for vSphere 4.1

The hugely popular Performance Troubleshooting for VMware vSphere 4 guide is now updated for vSphere 4.1 . 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:

  1. How to identify the problem using specific performance counters.
  2. Possible causes of the problem and solutions to solve it.

New sections that were added to the document include troubleshooting performance problems in resource pools on standalone hosts and DRS clusters, additional troubleshooting steps for environments experiencing memory pressure (hosts with compressed and swapped memory), high CPU ready time in hosts that are not CPU saturated, environments sharing resources such as storage and network, and environments using snapshots.

This document by no means covers the entire breadth of performance-related problems. We request the readers of this document, including VMware performance community members and vSphere administrators, to help us enhance this document by letting us know about all the performance problems they encounter in their vSphere-based virtual environments, including those that require elaborate troubleshooting steps.  We hope that the community will actively contribute by engaging in live discussions, providing feedback, and asking questions. All this input will serve as the topics for future updates
