Service timed out in munin

[rchmd]

Hello,

After my SD crashed on the three-year-old RaspberryPi, I've now installed Raspbian Stretch and reinstalled EBUSD. eBUS coupler Ethernet works great. EBUSD is going great.

Munin is also installed and the ebusd plugin is installed. Munin, however, reports the error "Service 'ebusd_power' timed out." (and all other ebus sensors) in /var/log/munin/munin-node.log

I have included other munin plugins without errors.

ebusd: 3.2 (build and installed in stretch)

I've changed in /etc/default/ebusd: EBUSD_OPTS="-d 192.168.178.33:5000 -s -p 8888 --loglevel=error"

root@raspberrypi:/home/pi# ebusctl i

Any ideas?

Quick question: which "eBUS coupler Ethernet" you use? I can't get my setup running.. It's not reporting CRC errors or similar, but my devices are not detected and I have the feeling that the CSV files on ebusd.eu are not even processed..

maybe munin is not allowed to connect to the port 8888, you might want to check that when running ebusctll with the user account that munin is running as.

Hello John,

thanks for your suggestion. Unfortunately, it works fine under the user munin:

pi@raspberrypi:~ $ sudo -u munin ebusctl -p 8888
localhost: listen
listen started
ehp SourceTempInput = 20.19;ok
ehp Status = 21.25;1.551;1.225;heat;08

and

Should I going back to jessie?

Dear rchmod, thank you - this is exactly the same I use, but I can't get it working with the CSV files. Although it reads and shows all messages properly, it never decodes them to any cleartext.

[john30]

@WWebber please don't mix completely different issues into one. I won't answer to yours unless you open a separate issue for that.

[john30]

@rchmd maybe a different user account is used for that one, I don't know

[rchmd]

Hello John. Thanks anyway. Thanks a lot for ebusd, a great tool. I'll get it working again for sure :-)

[john30]

it seems that munin runs the query as user root, so you could check that this works as well. It might be just some simple path issue as well. you could go and run /bin/bash /etc/munin/plugins/ebusd_power as user root. it is not supposed to run into a timeout of any kind.
oh, maybe this was the initial run during powerup? and maybe ebusd was not ready at that time. just an idea...
anyway, I'll add a timeout to the nc calls in the munin script, at least it should no longer run into timeouts then

[rchmd]

Hello John,
the result is:
root@raspberrypi:/bin/bash /etc/munin/plugins/ebusd_power
/etc/munin/plugins/ebusd_power: Zeile 6: /plugins/plugin.sh: Datei oder Verzeichnis nicht gefunden
ebusd_power_ehp_ActualEnvironmentPower.value 0

The same with "press" and "hours" --> Its working.

No, the issue is not only during powerup. But: I switched back to "Jessie" and ebusd is working fine with munin :-)

[rchmd]

Hello John,
I was wrong. In my previous post I connected to "Jessie". With "Stretch" I got the timeout:

root@raspberrypi:/home/pi# /bin/bash /etc/munin/plugins/ebusd_hours
/etc/munin/plugins/ebusd_hours: Zeile 6: /plugins/plugin.sh: Datei oder Verzeichnis nicht gefunden

root@raspberrypi:/home/pi# /bin/bash /etc/munin/plugins/ebusd_power
/etc/munin/plugins/ebusd_power: Zeile 6: /plugins/plugin.sh: Datei oder Verzeichnis nicht gefunden

root@raspberrypi:/home/pi# /bin/bash /etc/munin/plugins/ebusd_press
/etc/munin/plugins/ebusd_press: Zeile 6: /plugins/plugin.sh: Datei oder Verzeichnis nicht gefunden

[john30]

ok, still weird. did you try the latest update of ebusd-munin ?

[rchmd]

Hello John,
you got it! Great! Now it runs. 💯
I reduced the timeout to one second and the script still works fine. THANK YOU.
René

[john30]

great:)
