Hi,

I believe it’s currently not possibly to set an alert to notify when an average usage of multiple disks on a host has crossed a threshold. We’d need to apply that alerting per host, across multiple hosts (preferably filtering via a management zone or host group)

Custom event alerting should include the option to add multiple disks within the dimensions setting & base an average off of all of them. We’d need an alert created per host/entity.

Note: this is for some system backup servers.

Could this be done or is there another way?

Thanks,

Rhys

I believe you can set this at the host and the host group level.
