Graphs for dump1090 -- my version with install script

Maybe the hits were accounted for differently with the older amd64 fr24feed client.
Let’s see if it changes now that you are using the arm client.

Also i stopped collectd on accident -.-, now i have to wait 7 days for my graphs to get pretty again! :stuck_out_tongue_winking_eye:

Oh well, my graphs always look like crap when i’m working on the code.

I ran fr24feed on a RPi3 to get MLAT (that will change tonight). I ran the airspy on the same Pi before, with no difference. But we’ll se…

Don’t know how many times services has been stopped and you try to figure out why things fail :crazy_face:

Is it possible for the graphs to display local time, rather than GMT? I always forget whether the US Pacific time zone is GMT -7 or -8 for a given time of year.

They display the timezone set on the computer it’s installed on.

This should help you out:

sudo raspi-config

Thank you, sorry I missed that.

The graph y-axis is adjusted automatically based on the values received.
Is there a way to limit this behavior or making the steps smaller?

My number of aircraft is going to values between 120 and 135
But for this the chart goes up to 200 from 120 to show them.

I would now limit this graph to e.g. 150 ny myself or giving a smaller step from 120 upwards.

Possible? If yes, how?

Check the lower half of /etc/default/graphs1090

There i can adjust the graph size itself, but not the scaling, of the y-axis, or?

 40 # set custom y-axis upper limits for the individual graphs
 41 # for automatic upper limits leave them blank
 42 ul_message_rate=2200
 43 ul_aircraft=200
 44 ul_tracks=1000
 45 ul_range=250
 46 ul_maxima=2200
 47 ul_rate_per_aircraft=30
 48 ul_adsb_cpu=100 

These lines are not in the file i have.
Do i have to add the lines at the end?

# after saving this file, run
# sudo /usr/share/graphs1090/boot.sh
# to update the graphs and web interface

# set to 1 to enable farenheit instead of celsius

# set range graph to either nautical, statute, or metric
# set the right axis unit: (leftaxis, nautical, statute, metric)

# set graph size, possible values: small, default, large, huge, custom

# make the small graphs as large as the big ones
# run "sudo /usr/share/graphs1090/boot.sh" to adjust the web interface

# font size, default 10.0 (relative to graph size)

# set to 1 to draw a reference line at the maximum message rate

# if graph_size is set to custom, the following sizes are used:

# large graph dimensions are the actual graph area
# define the width of the larger graph, default is 1096, 960 also looks good in my opinion
# define the height of the larger graph, default is 235

# small graph dimensions are the actual total size
# width, default 619
# height, default 324

Just reset the configuration as described below:


Do whatever, i don’t care. You should be able to figure it out :wink:

I am, thanks :wink:


So I have used the graphs for a while now and I think it looks good (even though I am a beginner).

Maybe you experts can see if this is ok:

I know it is like asking how long a string is, but if you see something out of the ordinary I would appriciate if you told me.


You are getting a decent maximum range, and from your stats page on here you are receiving more than most stations near you and only a bit less than the one that is performing best. The gain looks like it’s set properly, so I’d say you don’t have much wrong there.

If you want better performance you’ll probably have to do it with antenna type and position, but depending on the traffic level near you, it might not make a huge difference.

Thanks… I have the Diapason from Jetvision and their 20m cable and bias-tee. Using flightaware pro plus stick… ANd it is on top of my houseroof… Just have to burn the school down that is about 100 meters away in the south direction :confused:

Don’t think you can improve your reception much.

You could always try a rtl-sdr v3 dongle instead of the Pro Stick+.

But that probably won’t help much, if at all.
Don’t know the exact signal level coming off your amplified antenna system.

Pretty sure you are maxxed out for the antenna location :slight_smile:

Great, you are to blaim for the awsome help :slight_smile: I really appriciate it!

If you have money to burn, get yourself the Airspy Mini and an RPi4 to run it at 20 MHz.

But as i said, i wouldn’t expect any significant improvement, no matter what hardware you use :slight_smile:

Looking at the memory utilization graph I wonder if this is normal behaviour or a slight memory leak?

There’s a few different things that use ram for temporary file storage, so usage does tend to increase for a while after a reboot. It does usually settle down at a fairly constant level though. That doesn’t look anything out of the ordinary to me, but you could keep an eye on it to see if it keeps growing.
