Collecting diagnostic information of all ESXi By using PowerCLi Script

VMware Technical Support routinely requests diagnostic information from you when a support request is handled. This diagnostic information contains product specific logs, configuration files, and data appropriate to the situation. The information is gathered using a specific script or tool for each product and can include a host support bundle from the ESXi host and vCenter Server support bundle. Data collected in a host support bundle may be considered sensitive.

This article provides the procedures for obtaining this diagnostic information of all ESX/ESXi hosts using VMware vSphere PowerCLI.
