Having many fields and tags beneath the very same measurement optimizes data transmission, which is crucial for remote gadgets sending metrics.
It truly is can be done to run a Python plan om my technique, only I don’t possess the programming skills to receive that Doing work. Any enable Within this regard is going to be A great deal appreciated.
Along with its clear tactic, this ensures contemporary and performant options without synthetic limitations. Factry built Factry Historian, an answer that collects method information from industrial techniques and stores it in InfluxDB.
I wrote some python scripts that did this and logged the information to some database or log file a while back but under no circumstances released them. I just took a have a look at them plus they use an previous perform that I don’t for a longer period use in order that they will need somewhat rewrite. Here is a sample output
