I cannot seem to find a FOSS version of what I know as industrial / plant process monitoring. Think Input A and B go to Process C which is making Amount N and passing them to output D. Usually you would see this as a series of pipes, valves, machines, etc. Maybe something like a SCADA visualization? IT would be excellent if it could be web based so I could share the view, and then feed it data from a back end db or similar. What I'm actually interested in it for: Network monitoring for natural disaster information in connected systems. That way I can display how a series of rivers is being tied together, work in things like flow rate, topping rates for dams, alert levels, etc. Then, when things are getting hairy, issue alerts and change upstream/downstream colours. Edit: Scadavis.io + node-red looks possible, but also looks like a complete pain.
