Enable metric collection at the child domain Device list node

Select Devices → <Child Admin Domain Name → Devices → <Device Name> → Setup → Performance Monitoring → Metrics to view the Metrics page.

Select the Inherit Settings? checkbox to inherit the settings from Parent Admin Domain. Deselect this checkbox if you do not want to inherit settings from Parent Admin Domain.

Select Yes or No against the choice Sensors can optionally collect CPU usage data. CPU sampling can affect overall sensor performance, so this option should only be enabled when troubleshooting. Would you like to collect CPU usage data?. This choice is available only if the Inherit Settings checkbox is deselected.

Select Yes or No against the choice Sensors can optionally collect port throughput usage data. On sensors with many monitoring ports, this option can produce a large quantity of data, so it is disabled by default to optimize Manager disk space. Would you like to collect port throughput usage data?. This choice is available only if the Inherit Settings? checkbox is deselected.

Click Save.

Note

When metric collection is enabled, devices automatically forward core metrics to the Manager. The reference to child admin domain here refers to the child admin domain of the root admin domain as well as the sub-domains of a child admin domain.
