Create Graphs/Charts of Arp list on CCR per vlan

I’m currently running a Unifi WiFi network with multiple SSID’s on multiple vlans. I am running this network with a CCR2116 as my router/firewall. Unif’s dashboard suck and i am unable to see a graph of concurrent devices connected to these SSID’s.

My thought is to use The Dude running on a HexS and have that poll the CCR arp list and create a graph for the dynamic complete status on a specific vlan. Maybe have it poll the CCR every 2-5min. Hopefully this will produce a graph/chart. I would like to have a graph/chart for each vlan/SSID.

Is this possible on The Dude? If so, can someone point me in the right direction?

Thanks

figured it out. In the Charts Data Source in code added

ros_command(" /ip arp print count-only where interface=v172 dynamic=yes complete=yes")
