Hi,
reagrding a Mail report i'm not yet sure whats the best way...
but you could just go wheneveryou want to the global settings
click on - ESM management
click on the Maintainance tab
click on the "View Statistics" button
in the "Time Range" field choose your custom time you would like to view
check the parameters you would like - CPU / Memery etc.
Refresh.
you could also try to take out reports from the VMware Platfrom.
Best Regards👍👍👍
