This gauge reports the connection setup rate, in connections per second, averaged over the last 300 seconds, for the specific protocol denoted by cufwConnProtocol. An admin compares this longer-window rate against the 60-second rate for the same protocol to tell whether an elevated setup rate for that protocol is a sustained trend or a brief burst. For example, if both the 60-second and 300-second rates are elevated for the same protocol row, the admin would treat that protocol's load increase as sustained rather than momentary.
