Adding devices to collectors occurs when you add the device to Zenoss.
The Add a Single Device page appears.
From the Collector list of options, select the collector you want to use to collect data for the device.
After you select the collector, the device appears in the Devices list, located at the bottom of the collector overview page.
You can move devices from one collector to another.
Select one or more device rows in the device list.
Select Set Collector from the Actions list of options.
Select a collector, and then click OK.
Zenoss moves the devices to the selected collector.
When a device is moved between collectors, the performance data is not moved. As a result, historical data for the device may not appear in reports and graphs.
