I was thinking about how to extract some useful parameters from dump1090-mutability hourly log and send them to ThingSpeak in order to build a performance graph on their web site. That would make almost superfluous to collect and write data locally, saving SDcard life and filesystem space. I'm not sure about what data should I grab...number of airborne position messages? total usable messages? Any suggestion appreciated.
Check out my custom image dashboard! It grabs all kinds of stuff from dump1090. Aircraft, messages total, max range Those are probably the top metrics. # HELP dump1090_messages_total Number of Mode-S messages processed since start up # TYPE dump1090_messages_total gauge dump1090_messages_total{time_period="latest"} 46909755 #
