1090 graphs and N2

Hi

Just set up my N2 to run the current airspy tweaking but I can’t seem to get the 1090 graphs to work. Installed the relevant 1090 graph script, but the graphs aren’t generating.

graphs1090 is getting the data mainly from the system or the json of dump1090/readsb.

What graphs are exactly missing?
Is collectd installed properly? Any output from the script you installed it with?

This is what I have at the relevant IP and agree something missing I think. You are right re collectd, here is an error

All done! Graphs available at http://192.168.0.249/graphs1090
It may take up to 10 minutes until the first data is displayed

That’s the problem.
Follow the instructions as described in the last line

Note: Please for next time use the “code” block for documenting logs here. It’s hard to read otherwise. You can find that in the editor by using “</>” after you marked the text you want to show as code

sorry that was a cut and paste from the SSH window

I am not sure what instructions you refer to?

This one gives you the instructions how to identify the issue:

See “systemctl status collectd.service” and “journalctl -xe” for details.

Excecute these and share the results here

Please… write these outputs as code here. This is pretty hard to read.

collectd is not running. the start ended with a Failure
I am not an expert, maybe @wiedehopf can help

That’s the part which is important:

check that python is installed properly on the device

Try the install script again.

Yes I shall try again, do I need to uninstall it first?? I did have a look at the non standard config section in regards to not finding the graphs and that it mentions “/etc/collectd/collectd.conf’” but it cant find that collectd.

Hmm another error on the install script

Install in progress, this shouldn’t take longer than a minute or two …
Job for collectd.service failed because the control process exited with error code.
See “systemctl status collectd.service” and “journalctl -xe” for details.

And try once more in 2 minutes or so.

Job for collectd.service failed because the control process exited with error code.
See “systemctl status collectd.service” and “journalctl -xe” for details.

Another error, different line.

For you info though, the airspy script fresh install worked a charm, installed 2.2 RC3

The only difference from it installing previously with no issue, is that I tried Ubuntu for the first time, only because I have a N2+ on the way and it is the “home” OS for hard kernel
