ffnodestats Idea and stuffs: database storing connection snapshots, consisting of: UnixTimestamp RouterMAC(ID) ClientMAC possible requests to database: >routers(from,to) -> unique router MACs >clients(from,to) -> unique client MACs >router_clients(from, to) -> macs of unique connected clients to router in that time span for a router graph time/clients just do multiple router_clients(from,to) requests for different spans and visualize the length of the client array client_connections(from, to) -> return an array of connections in form of {routerMAC, fromStamp, toStamp} this works by assuming that if a client is missing in a snapshot or changed routers, the connection was lost for a timeline of the client: use client_connections(from,to) visualize ;) for a timeline of router where you see when which client connected: use router_clients for a span for each client use client_connections for that span and filter for connections to that router visualize
