Change the zone for a Data Collection Device

Normally, you assign a Data Collection Device (DCD) to a zone as part of the initial setup for that device. But you can change the zone to which a DCD is assigned as needed.

1. From BIG-IQ, at the top of the screen, click System, then, on the left, click BIG-IQ DATA COLLECTION > BIG-IQ Data Collection Devices.

   The BIG-IQ Data Collection Devices screen opens listing the DCDs in the cluster. The Services column lists the BIG-IP services monitored by each DCD. If no services are enabled for a DCD, this column displays Add Services instead.

2. Under Device Name, select the DCD that you want to revise.

3. On the DCD properties page, click Edit to display the Edit Zone popup.

   • To use an existing Zone, select the zone you want to assign to this DCD and click Continue.
   • To use a new Zone, select Create New, then type the name of the zone to want to create and assign to this DCD and click Continue.

4. Click Save & Close to close the DCD properties screen.

5. Use SSH to log in to DCD as root.

6. Type bigstart restart elasticsearch and press Enter.

7. Repeat the last three steps for each DCD that you want to move to this zone.

   Note: As you run this command on each DCD, it momentarily stops processing DCD data, so the data routes to another node in the cluster and no data is lost.

You can now assign managed BIG-IP devices to this zone for data collection.
