I was thinking a bit about the MQTT-broker and dashoards. We are planning on collecting data from OPC-UA in some of our machines.. I want to create some dashboards with data from the machines in the future.. Will the broker run well if publishing around 40-50 variables from 10-15 machines in "real-time" or will it break ? Also is there any good scada-software to use for this ? one could of course use grafana for this but as of my understanding it is not meant to be used with live data and it could also be nice to use some graphics for these dashboards..
