I had the same thoughts and experience. I live in the US, and here we seem to still have some traffic flying and at 30% or so of previous levels. Much of the world seems to be much lower traffic ( https://tar1090.adsbexchange.com ) and thus the earlier high levels reported over the busy areas in Europe have dropped significantly more with some sites having no traffic at all in a 24 hour period. Thus, those European sites have moved lower in the stats and others are moving higher with the limited flights our receivers can track. These are all just the ripple effects of the changes in the current flight patterns. When this gets back to normal, expect huge changes in the stats. Just my thoughts, and I could be totally off base.
Iām sure that you are right. I expected my stats to fall off of a cliff, but I am between PDX and SEA, so I pick up most of the northbound traffic to Seattle, as well as some of the great circle traffic between Asia and SFO/LAX. I think the other thing that has helped is that I have 3 fairly busy municipal airports within the range of my receiver and have been getting (comparatively) massive amounts of GA traffic whenever the weather is nice-ish.

2200-2500 down to 500-600 hereā¦ Ranking did not change that much.
Thanks to Ramstein Air Base, otherwise i would have another 30% less traffic
Was reading this news yesterday, some U.S. airlines want to cut more flights but now need government approval to do so due to rules of the airline bailout program.
Something slightly different - the reduction in air traffic has made a considerable difference to the data usage by my adsb pi:

What traffic do you have?
Even in high times with >120 aircraft my devices used approx 1 GB of Bandwidth per day.
As itās internal, do you run any other network services in your local network causing this?
I really like that. Those are the sort of graphs and figures that make me go all squiffy! How can I get that please?
Thatās the web interface of vnstat:
https://humdi.net/vnstat/
But it includes the local traffic from/to the device as well. vnstat cannot filter out that local traffic as far as i know.
I am currently playing around with darkstat which is able to filter local traffic.
Install vnstat which is what gathers the data. Itās very lightweight.
sudo apt install vnstat vnstati
Then I use a cron entry to run a script to generate the images:
#!/bin/bash
vnstati -hs -o /usr/share/dump1090-fa/html/net/summary.png
vnstati -d -o /usr/share/dump1090-fa/html/net/day.png
vnstati -m -o /usr/share/dump1090-fa/html/net/month.png
vnstati -t -o /usr/share/dump1090-fa/html/net/top.png
They are created in a sub directory of the dump1090 html folder which makes the accessible. There is a basic html file to display them:
<!DOCTYPE html>
<html>
<style>
img {
max-width:100%;
height:auto;
}
</style>
<body>
<h1>Network bandwidth usage</h1>
<img src="summary.png" alt="Summary"></p>
<div style="float: left;">
<img src="day.png" alt="Days">
</div>
<div style="float: left;">
<img src="month.png" alt="Months"><br/>
<img src="top.png" alt="Top10">
</div>
</body>
</html>
You can then see it at /dump1090-fa/net
Thatās mostly for adsb feeding, with a bit of local data if I happen to look at the map. I feed 7 different networks, with 5 instances of mlat client running. There are also 2 full beast streams going to private networks.
Traffic wise in normal times I see 300-400 aircraft at peak times, with 2800 messages per second.
Edit - added vnstati to install command.

OK with that message rate itās clear having a higher traffic. Mine is up to 150 aircraft with max 1300 msg/second in busy times
Oh you absolute star, thank you. Iāve run it once manually to test and set a cron job for a couple of minutes before midnight (but I guess I could do it more often so itās regularly updated). Itās visible here (but of course wonāt be meaningful until itās got a full day).
I canāt generate images. The cron commands do not work.
Those commands arenāt cron commands - save that as a bash script and make it executable, then call the script using cron, which will look something like:
*/30 * * * * /bin/bash -c "/home/pi/vnstatpng.sh"
You can check that the commands work by just running them individually on the command line.

You also need to install vnstati:
sudo apt install vnstati

Thanks, vnstati was what I missed.
Everything installed and cron script works, BUT when I go to myip://dump1090-fa/net I get a 403 Forbidden error. How can I fix it?
Are the files in the appropriate folder of the webserver?
What is the webserver called? Apache is not installed.
Where should the webserver files be located?
Vnstat image files are in /usr/share/dump1090-fa/net. They were created from the cron script above.
I donāt know if I need to add the html from above or where to add it or what it should be named.
Iām a total noob.
If you are using dump1090-fa then you should have lighttpd installed.
Try adding the name of one of the image files to see if you can see it, eg
<ip>/dump1090-fa/net/summary.png
If that works, then adding the index.html to the directory should enable you to see it at /dump1090-fa/net/
By default, lighttpd wonāt let you see a directory listing. but you should be able to see a file you request explicitly.
