ESXTOP – CPU Overview

What is ESXTOP?

The VMware esxtop tool provides a real-time view of ESX/i Server worlds. The term world refers to processes running on the VMkernel. The focus on this deep dive will be CPU usage.

There are three types of worlds:

System: The worlds that are needed to perform various system services. These include one idle world per physical CPU that runs when there is nothing else to run on that physical CPU, helper worlds for performing asynchronous tasks and driver worlds.

Service Console: The world for the service console. It always runs on physical CPU0. The service console does not exist on the ESXi server.

Virtual Machine: The world for each virtual CPU. This is the world you look at when troubleshooting.

The vSphere® 5.1 Ultimate Bootcamp

Prior to the release of vSphere™ 5.1 the training team began work to update the course to include all the latest technologies that were released in August by VMware®. Even though these updates were considered minor, the changes to what administrators have seen may be considered major! There are new additions that cannot be performed through the standard vSphere™ Client! That was a sad day for some of us, now we are forced to use the vSphere™ client and the new web client. Regardless our dedicated team has put together some great content and labs in the newly updated VMware vSphere™ 5.1 Ultimate Bootcamp®. They have included the Single Sign-On Service and Inventory service we all need to deal with during an install. These components have both pros and cons, which have been addressed by our technical team! They have also added the improvements made to the storage interaction. And of course they have added labs using the vSphere™ Web Client! Check out the new outline and feel free to ask experts questions on the VMTraining Forum!
