Cool Tool: ESX System Analyzer (a fling from VMware Labs)

The ESX System Analyzer (http://bit.ly/AvIbO3) is a tool designed to help administrators plan a migration from ESX to ESXi. It analyzes the ESX hosts in your environment and, for each host, collects information on factors that pertain to the migration process:

  • Hardware compatibility with ESXi
  • VMs registered on the ESX host, as well as VMs located on the host’s local disk
  • Modifications to the Service Console
    • RPMs which have been added or removed
    • Files which have been added
    • Users and cronjobs which have been added

This tool also provides summary information for the whole existing environment

  • Version of VMware Tools and Virtual Hardware for all VMs
  • Version of Filesystem for all datastores

By having this information, administrators can determine what tasks need to be done prior to the migration. Examples include:

  • Relocate VMs from local datastores to shared datastores
  • Make note of what agent software has been added to the host and obtain the equivalent agentless version
  • Replace cronjobs with equivalent remote scripts written with PowerCLI or vCLI

Configuration is simple, just follow the user guide provided (http://bit.ly/x7vPSh)

Once a report a run against your servers, you have access to several interesting reports. Personally I’ve used this tool when upgrading from ESX 3.5 to ESXi 4.1 and I will use it again soon when upgrading to vSphere 5.
