Confirm that alerts and
events can be sent to an alternative device in a Data Collection Device cluster if one goes off line
Before you start the upgrade process, confirm that
your managed BIG-IP devices can send alerts or events to more than one device in the Data Collection Device cluster so that when a particular device in the Data Collection Devicecluster is being upgraded, data
automatically routes to another device in the Data Collection Devicecluster.
- Review the data routing configuration for all of the managed BIG-IP devices that send data to your DCD cluster. If you find a BIG-IP device that is configured to send data to only one device in a DCD cluster, change that configuration before proceeding. Refer to the BIG-IP device documentation onsupport.f5.comfor details on how to configure the BIG-IP device for DCD cluster routing.
- Review the monitoring configuration for all of the managed BIG-IP devices that send data to your DCD cluster. Make sure that each BIG-IP device is configured to send data to an alternate device in the DCD cluster if another device goes offline. If you find a BIG-IP device that is not configured with appropriate monitors, change that configuration before proceeding. Refer to the BIG-IP device documentation onsupport.f5.comfor details on how to configure BIG-IP monitors correctly.
