The management console automatically evaluates server traffic from each monitor feed and assigns the most appropriate monitor feed to a server.
When a monitoring device initially observes a TCP session, the management console assigns the monitor feed that sees the highest inbound packet volume to the server. During the first hour, the assignment can change every 5 minutes depending upon the monitor feed with the highest packet volume. After an hour, the packet volume on a monitor feed must be significantly higher for the management console to automatically change the monitor feed assignment.
If the packet volumes are similar, the management console assigns the monitor feed with the faster Server Connection Time (SCT). Note that you can override the automatic monitor feed assignment and permanently assign a particular monitor feed to a server.
In a WAN-optimized environment, the management console assigns the best Packets monitor feed to monitor the Server segment and automatically calculates response time metrics from all WAN optimization devices.
If a server moves to a different location on the network, the automatically assigned monitor feed would automatically change to the monitor feed that now sees the server traffic. It can take up to 1 hour for the management console to change the monitor feed assignment.
To enable the management console to immediately observe traffic from more than one monitor feed, for example, as part of a load-balanced configuration or for disaster recovery and failover, you can assign a secondary monitor feed to a monitor feed.
