Server Disk attributes
This data set contains information about disk usage for a server.
Note: If you define a threshold for this data set, any events are not displayed in the Events tab of the Application Performance Dashboard. Instead, they are sent to Netcool/OMNIbus if event forwarding is configured.
This data set is displayed as KVM SERVER DISK in the threshold editor.
