F5 high availability in NPM
High availability (H/A) is configured on the device level. It does not matter whether you have a GTM or LTM installed on the device, the module is covered by H/A. Devices are connected in traffic groups. If one device fails, another device in the group handles its requests. Devices in a traffic group synchronize the configuration. The configuration is reflected by the synchronization status.
In NPM, we poll the failover and synchronization status.
Devices in one traffic group are connected by dotted rectangles on the Balancing Environment resources. Display the tooltip to see details about the H/A failover and synchronization status.
You can see the H/A statuses in tooltips, and on the LTM or GTM detail views. The GTM or LTM details resource shows the H/A status and synchronization status. In the High Availability resource, you can check the details about other members of the traffic group.
