Version 4.x Code MRTG Configs
Global Metrics
The metrics in this section are metrics that are inclusive
of the entire BIG-IP, rather than individual components such as virtual
servers or nodes. There is also a section on individual metrics.

Bandwidth out of Each Interface
Bandwidth out of each interface is part of the standard
IF-MIB, and the standard cfgmaker script supplied
with MRTG will provide you with a configuration for all of the Ethernet
interfaces. This is the same no matter what version of code you are running.

Connections Per Second
Connections per second are the most important metric to keep track of for any
load balancer as it is typically the most resource-intensive, especially for
web sites with small files and a high rate of connections.

Concurrent Connections
Another very useful metric to trend is the total number of
concurrent connections. This counts the number of sessions the BIG-IP is
handling, which are the open TCP sessions that users have established. UDP
isn't included in this of course, as UDP is a connectionless protocol.
