It looks like USB CPU utilization went up but overall CPU and memory utilization went down. Are you experiencing issues related to the increased USB CPU utilization?

[foxhunter]

I assume you have updated recently and causing the problem where lots other users discussed.
It’s a library issue. In the thread you will finde different solution.

FYI New Pi Kernel causes dump1090-fa to run much harder

As long as ADS-B tracking is the only thing the RPi has to do… However i would also be concerned if my CPU utilization for a single thread jumps from below 20 to over 50% in usage

yep, that’s it. dump1090 cpu usage dropped from 12-17% to about 2%. thank you

How do you get the fancy graphs on raspi?

Nothing special)

cd ~
sudo bash -c "$(wget -q -O - https://raw.githubusercontent.com/wiedehopf/graphs1090/master/install.sh)"

Then go to

http://192.168.xx.xx/graphs1090 from PC (xx.xx. - your rpi IP adress)
or
http://127.0.0.1/graphs1090 from rpi browser

From here: GitHub - wiedehopf/graphs1090: Graphs for readsb / dump1090-fa / dump1090 (based on dump1090-tools by mutability)

Nothing special)

Nothing special to download but a lot of work by @wiedehopf to modify the old script and support it

a lot of work by @wiedehopf to modify the old script and support it

The best part of modification from old script of J Prochazka to current script of @wiedehopf was to eliminate its dependency on “Web Portal”, and make it a stand-alone app. Good work by @wiedehopf, who has done other improvements/enhancements as well.
