Log Dateien

Hallo zusammen,

Daten wie Raumtemperatur oder Energieverbrauch einiger Komponenten, würde ich gerne aufzeichnen und auch Visualisieren. Wo speichert man diese am besten ab? SQL Datenbank? Damit wäre es dann relativ einfach die Daten zu visualisieren. In welchem Intervall kann ich loggen ohne den BUS zu überlasten?

Hat hierzu jemand erfahrungen?

Julian, what does your system look like? You would need some device that is running all the time and that can take information from the bus. In my case I use a Rasberry Pi to receive data from the bus and write it to a database using RRD-tool. That tool also can generate graphs. I log that data every five minutes. In parallel, I write key data to a text file daily. That delimited data can be easily imported into MS-Excel, providing full flexibility in data analysis.

Of importance is also your level of experience with one tool or another, or your willingness to pick up that knowledge.

In principal anything is possible. A good start is to figure out what it this that you want to visualize and/or analyze (the requirements), and what your current capabilities are (interfaces, hardware, tools, knowledge). You can than figure out if there is a gap, and get to work.

Hi Bram,

thank you for your answer.

There is no system yet. I am in the planning phase at the moment. So I want to pick up some ideas of other users to find the best solution for me.

A Rasberry Pi is already on the list for logging and visualization, but probably I will use a home server for this. The server is needed anyway for the music and data storage.
I will have a closer look at your PRD-Tool. GPU looks good.

Thank you so far. Other solutions are very welcome.
