I have noticed what might be a small firmware bug. If you go to the Log --> System Statistics page, the Sessions and New Sessions/Sec counters always remain at 0, even with several workers actively online.
As a general rule, I find total sessions and sessions/sec to be useful for getting a snapshot of how busy the router is at any given time. I would like to see this working correctly.
In addition, I would like to see total sessions, sessions/sec, current CPU usage along with load average , and unit temperature all available on the System Summary page. I would also like to see CPU usage along with load average available at the top of the page on the Log --> System Statistics page.
When I say load average, I mean the part of the output of the linux uptime command that shows the system load the past minute, 5 minutes, and 15 minutes.
