System Performance Summary report displays 'n/a' for Disk I/O statistics collected by the IC agent (4305841)

The "System Performance Summary" report can be found in the Hosts/Reporting module - see the "Performance Summary Table" view.

This report has a "Disk I/O" column that only populates for hosts monitored by the Legacy OSCartridge agents. It displays "n/a" for hosts monitored by the IC agents.

The "Disk I/O" column is populated with the following value:

first item of <currentRow>/storage/logicalDisks/utilization/current/average

Hosts monitored by the IC agent have the following Data Tree structure. There is no "Utilization" node, which is probably why n/a is being returned:

Configuration -> Data -> Hosts -> All Hosts -> hostName -> Storage -> Logical Disks -> diskName

Hosts monitored by the Legacy OSCart <os>_System agent have the following Data Tree structure, which fits the "System Performance Summary" report's search for a Utilization node under 'logicalDisks':

Configuration -> Data -> Hosts -> All Hosts -> hostName -> Storage -> Logical Disks -> diskName -> Utilization -> Current (and there is an Average row in the 'Current (MetricValue)' table.

There is a "Disk Utilization" value for hosts monitored by the IC agent. The "System Performance Summary" report could probably use this in the query instead:

Configuration -> Data -> Hosts -> All Hosts -> hostName -> Storage -> Disk Utilization -> Current (and there is an Average row in the 'Current (MetricValue)' table'
