    (that's bug was what oblivian was referring to)

    Anyway, get yourself some graphs, they look nice: https://github.com/wiedehopf/graphs1090#graphs1090

    Indoor antennas are usually whip antennas, those can be greatly improved:

    The graphs are already running, this was the third thing i installed on the device ;-)

    For the antenna i am good so far. Living close to EDDF with lots of traffic. Range shows 100 NM with some peaks up to 150 NM. I will check the antenna improvements later, maybe i go with an outside one.

    That was a dig at the devlopers, not the fact you didn't see it straight away

    To improve range/plane count, place antenna:
    (1) Near a window
    (2) Over a metal plate or food can

    Thanks for your hints, the antenna is already close to a window in my rooftop home office. Good suggestion with the metal plate, will give it a try.
    The antenna is already catching signals from up to 240 km stable with some peaks of up to 300 km

    The interesting fact is that i have a 360° view documented on my stats pages, even if there is only one windows heading east
    Seem to be the receiver FR Pro Plus is really good.

    I have another question, not directly related to the feeders, but the 1090 Graphs. Question should go to @wiedehopf but maybe interesting for others.

    In the graph i do not have charts for "CPU utilization". It only shows a link as text with a placeholder for a broken image, which ends up in an error 404 while clicking on it.

    Any idea why the CPU overall utilization is not shown?

    Let's see this:

    cat /etc/os-release | grep PRETTY
    collectd -h | grep http

    Here we go:

    PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
    collectd 5.7.1.git, http://collectd.org/


    thanks for your quick response

    and in case you need the content of the aggregation-cpu folder:

    -rw-r--r-- 1 root root 387228 Jul 19 12:57 cpu-idle.rrd
    -rw-r--r-- 1 root root 387228 Jul 19 12:56 cpu-interrupt.rrd
