Graphs not being generated correctly

[satmandu]

I see this on a Raspiberry Pi 4B running Raspberry Pi OS 64-bit:

Are there specific logging settings I need enabled to get these to show up properly?

hmm, I don't expect any additional setting to enable default graphs. Could you please run the following commands and provide the output?

$ sudo snap logs -n 200 adsb-box.collectd
$ sudo snap run --shell adsb-box.graphs-gend
$ cd $SNAP
$ env XDG_DATA_HOME="$SNAP/usr/share" FONTCONFIG_PATH=$SNAP/etc/fonts bash -x usr/share/graphs1090/graphs1090.sh 24h 0.7

Now I see this:

[tsunghanliu]

Are all graphs generated correctly now? I'm not sure if it's just because the graphs were not ready at that moment.

Another points is that the /var/snap/adsb-box/current/disk.conf doesn't have right settings and causes the disk graphs wrong. You can change the content to the following and see if this helps.

DISK="mmcblk0"
MOUNTPOINT="/var/lib/snapd/hostfs/root"

[satmandu]

Here is what I see now after modifying that config file thus, since my boot disk is an external USB volume:

DISK="sda"
MOUNTPOINT="/var/lib/snapd/hostfs/root"

(This is after rerunning the commands in the previous comment.)

[tsunghanliu]

I forgot to mention that you need to restart the snap (at lease the collectd & graphs-gend) to apply the change.

$ sudo snap restart adsb-box.collectd
$ sudo snap restart adsb-box.graphs-gend

If you didn't do these, please try again.

also, could you please /var/snap/adsb-box/current/collectd.log and output of `find /var/snap/adsb-box/common/collectd/rrd/? I am wondering if collectd gets data correctly or graphs-gend can't find the DB.

No changes seen in graph output:

[satmandu]

(I do not see any changes in more recent versions of collectd which might change things on a Raspberry PI.)

[tsunghanliu]

The adsb-box has its own collectd, so the version of collectd on Debian shouldn't affect the snap.

I revisited your collectd.log and found that there are many rrdtool update errors since June:

[2022-06-08 11:16:16] rrdtool plugin: rrd_update_r (/tmp/rrd/localhost/dump1090-localhost/dump1090_cpu-demod.rrd) failed: mmaping file '/tmp/rrd/localhost/dump1090-localhost/dump1090_cpu-demod.rrd': Invalid argument

I'm not sure if they are caused by data corruptions. To recovery this, you can try these steps:

1. sudo snap stop adsb-box
2. back up /var/snap/adsb-box/common/collectd/rrd/localhost
3. remove /var/snap/adsb-box/common/collectd/rrd/localhost/dump1090-localhost/dump1090_cpu-demod.rrd
4. sudo snap start adsb-box and check the graphs

You may run fsck to check the disk as well.

[satmandu]

That fixed it!
