When you lodged a support request to VMware Technical Support, they routinely requests the diagnostic information from you. This diagnostic information contains product specific logs and configuration files from the host on which the product is run or from the host that may have issues and need further troubleshooting. This information is gathered using a specific script or tool within the product. Collecting diagnostic information is the same as collecting or gathering log files. This post will provides procedures for obtaining diagnostic information for ESXi 5.0.
