Check Logging Node health
You
can use the Logging Configuration screen to review the overall health and status of the
Logging Nodes you've configured. You can use the data displayed on this screen both
before and after an upgrade to verify that your Logging Node cluster configuration is as
you expect it to be.
Note: Perform this check on the BIG-IQ®; not on the Logging
Node.
Deactivate Logging Node services
Before you can successfully upgrade
your Logging Node cluster, you must deactivate the services that send alerts or events
to the Logging Nodes.
Note: Perform this check on the BIG-IQ® Centralized Management
device; not on the Logging Node.
The services on your Logging Nodes
stop. Consequently, the Logging Nodes stop accepting alerts or events from the BIG-IP®.
Stop Logging Node cluster
As part of preparing to upgrade your
Logging Node, you must shut down the cluster so that upgraded devices and devices that
have not yet upgraded do not communicate during the upgrade.
Important: If you omit this step, the cluster
will not function after the upgrade.
Note: You must perform this task on each
device in the cluster (that is, each Logging Node device, the BIG-IQ® Centralized Management device, and the BIG-IQ HA
peer).
Once you have stopped the cluster
for each device, you can proceed with the cluster upgrade.
