Concurrent Online Users



  • Hi.

    I have tweaked my Pfsense install quite harshly to my needs (a free WiFi hotspot with tweaks to the way the captive portal works).

    I would like to have an email sent weekly which shows the number of captive portal users per day (this is no prob), but would also like to be able to see how many of these were online at anyone time.

    The DHCP server status shows clients as "online" and "offline", but where does it get this information from?

    I have not looked into this yet, but thought perhaps someone could stop me from scratching around through files looking for the best way to obtain this information!

    Thanks for any pointers.



  • It appears this information comes from the ARP table, and so this is where I have grabbed the qty from.
