    Your graph looks like your gain is low.

    Most likely you have better results at 1% to 5% Messages > -3dB
    That's in the first graph.

      Hi Guys!
      I also installed the Graphs1090 and it looks pretty cool!
      Anyway i also noticed the different plot in the signal section:dump1090-localhost-signal-24h.png

      I guess my noise floor is pretty high!
      My weakest signal is only -19.7!

        This is my log, stats for the system are not working.

          So the system stats are just empty?

          What system is this? (which operating system, so Raspbian Stretch for example or whatever you put on the sd-card)

            Yes system stats are empty.
            Raspberry Pi 3B+ and Raspbian Buster.
            ADSB data are working great tho!

              That's strange.

              So empty pictures huh?
              No clue what's happening.

              Did you have the receiver project graphs installed before?
              Not sure where "could not decode JSON" comes from but it shouldn't have anythign to do with system graphs rather ADS-B graphs.

              Do a reboot, wait a minute and show me the log again please.

              Oh maybe the system time is set wrong?
              What's the output for:
              date -u

                date -u
                Date is ok, date-u shows the UTC hour.
                It worked in the beginning but after a while it stopped and never worked again.
                It's been running for about two weeks.
                What i really need are ADSB data so for now this stats are enough for me.
                I'll reboot and let you know!

                  You can try deleting the database files in this folder:

                  /var/lib/collectd/rrd/localhost

                  Delete everything but dump1090-localhost (ADS-B data).

                    Hi!
                    I uninstalled the software and deleted everything.
                    Than i had a problem reinstalling it but removing manually "collectd"(purge) did the trick.
                    Than i changed dump1090-fa with dump1090 in the conf file.
                    Everything is working great now!
                    There is only one problem with the log:

                    Is this normal behaviour?
                    Thanks!

                      I have no clue where that's coming from.

                      Everything working?
                      You can try putting an # in front of the line with URL_978 in the /etc/collectd/collectd.conf and see if that helps.

                        Decommenting the 978 URL worked!

                        Maybe someone else is having the same issue, who knows... you should put it in your official guide.
                        Anyway it's a real useful software.

                        What about the writing data? Any issue with the SD card wearing? Will they occupy a large amount?
                        Cheers and thanks again!

                        P.S.
                        I have a GitHub repository that includes some kind of METAR web UI. Take a look here:

                          The wear is usually not a problem.
                          If you want to reduce the amount of writes, there is a section on that: https://github.com/wiedehopf/graphs1090#graphs1090

                          The database will be around 20 MB i think.
                          You can check like this:
                          du -sh /var/lib/collectd/rrd/localhost

                          The size should be static, it doesn't grow.

                          For me it doesn't complain that loudly if the 978 URL is set and nothing is there.
                          Are you running pihole on the same pi by chance?
                          Most people don't check the logs anyway

                              You see it gets an empty file, so it complains about that.

                              If it gets no file, it doesn't complain.
