Beginner - Setup successfully on PIAWare, but no aircrafts

[magnum]

The system is set up brand new with a 16 GB SD card, currently it shows 12.5 GB and i agree, the files should not be empty.

i was running your commands and now the files are not empty any longer:

-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-idle.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-interrupt.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-nice.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-softirq.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-steal.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-system.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-user.rrd
-rw-r--r-- 1 root root 387228 Jul 19 13:36 cpu-wait.rrd


Checking the stats and now the CPU utilization is loading as graph

Thanks for quick support!

Those two files really shouldn't be 0 in size.
Let's hope they get properly created this time around.
Any chance you have insufficient disk space? (there even is a graph for that you can check)

So to reset those files, just delete database files for the cpu graph:

sudo systemctl stop collectd
sudo rm -r /var/lib/collectd/rrd/localhost/aggregation-cpu-average
sudo systemctl restart collectd

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
-rw-r--r-- 1 root root 387228 Jul 19 12:56 cpu-nice.rrd
-rw-r--r-- 1 root root 387228 Jul 19 12:57 cpu-softirq.rrd
-rw-r--r-- 1 root root 387228 Jul 19 12:57 cpu-steal.rrd
-rw-r--r-- 1 root root 0 Jul 18 20:28 cpu-system.rrd
-rw-r--r-- 1 root root 0 Jul 18 20:28 cpu-user.rrd
-rw-r--r-- 1 root root 387228 Jul 19 12:56 cpu-wait.rrd

Here we go:

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

thanks for your quick response

[wiedehopf]

Let's see this:

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

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?

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

[ATTACH=CONFIG]10920[/ATTACH] [ATTACH=CONFIG]10921[/ATTACH]

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 was searching for my problem here in Forum and stumbled across the wrong port number only by chance. Sorry for it.

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

[magnum]

The thing with the port number: you should be able to use AVR format from port 30002, but that is buggy, beast from 30005 works much better.
(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.

It still amazes us that there hasn't been a re released fix version /removed option with the number of times it's pooped up and we've pointed it out as a bug

Other quick question:

The tracking is running, my page on FR24 says "Receiver online and sending data", but the values are still "0"
Does this take a while?

I also received a confirmation from FR24 for beeing a feeder and that my account has been upgraded. But it still shows "Silver" as i had before.
That's the less critical question

/EDIT: Forget it, Stats are working now. It took a few minutes to update.
