Hello,
I installed netdata directly to my Armbian Odroid XU4, because of track the temperature. But the Sensors section shows only voltage. I have tried to google the solution, but didn’t find anything about that. On my another machines Raspberry Pi 3B+ and Odroid N2 works perfect. I can’t move with the last one. Where could be the problem in not-showing temperature?
Thank for any help.
Tom
Welcome!
Hmmm I’m not that familiar with that device but it looks like maybe the temperature might not be getting picked up out of the box like it would for a Pi because it’s probably a little specific to that device and we might not have a default collector for it yet.
I did find this blog post that has a custom python collector that seems to maybe be close to what you would need.
Basically it’s a little custom python script you’d need to install to make netdata aware of the temperature.
Some more info here on custom python collectors
If you are interested in playing around with the python I’d be happy to try help you get the above script working and we could maybe add it in here for others in future to be able to use.
Hello,
thank you very much for this instructions and links. It’s a bunch of interesting material to learn. Yesterday I was trying to create the collector according to the instructions in the first link, but I don’t know where I created the bug. I couldn’t get the script to work. Anyway, I’m going on vacation tomorrow, so I will continue with this next week. Then I will let you know the progress. I’m not giving up!

I’m back. According to the tutorial in the first post, I made the python file based on this script:
from bases.FrameworkServices.ExecutableService import ExecutableService
ORDER = ['temperature']
CHARTS = {
'temperature': {
'options': ['temperature', 'Temperature', 'Celsius', 'temperature', 'custom.temperature', 'line'],
'lines': [
['zone0', None, 'absolute', 1, 1000],
['zone1', None, 'absolute', 1, 1000],
['zone2', None, 'absolute', 1, 1000],
['zone3', None, 'absolute', 1, 1000],
['zone4', None, 'absolute', 1, 1000],
]}
}
class Service(ExecutableService):
def __init__(self, configuration=None, name=None):
ExecutableService.__init__(self, configuration=configuration, name=name)
self.commands = {
'zone0': ['cat', '/sys/devices/virtual/thermal/thermal_zone0/temp'],
'zone1': ['cat', '/sys/devices/virtual/thermal/thermal_zone1/temp'],
'zone2': ['cat', '/sys/devices/virtual/thermal/thermal_zone2/temp'],
'zone3': ['cat', '/sys/devices/virtual/thermal/thermal_zone3/temp'],
'zone4': ['cat', '/sys/devices/virtual/thermal/thermal_zone4/temp'],
}
self.order = ORDER
self.definitions = CHARTS
def check(self):
data = self._get_data()
if not data:
return False
return True
def _get_data(self):
data = {}
for key in self.commands:
self.command = self.commands[key]
try:
out = int(self._get_raw_data()[0])
data[key] = out
except (ValueError, AttributeError):
continue
return data
I saved it as temperature.chart.py file in the folder /opt/netdata/usr/libexec/netdata/python.d - the only folder that includes *.chart.py files.
Next (again - according to the tutorial) I added the line temperature: yes to the python.d.conf file saved in the /opt/netdata/usr/lib/netdata/.
So the file looks like this:
# netdata python.d.plugin configuration
#
# This file is in YaML format.
# Generally the format is:
#
# name: value
#
# Enable / disable the whole python.d.plugin (all its modules)
enabled: yes
# ----------------------------------------------------------------------
# Enable / Disable python.d.plugin modules
#default_run: yes
#
# If "default_run" = "yes" the default for all modules is enabled (yes).
# Setting any of these to "no" will disable it.
#
# If "default_run" = "no" the default for all modules is disabled (no).
# Setting any of these to "yes" will enable it.
# Enable / Disable explicit garbage collection (full collection run). Default is enabled.
gc_run: yes
# Garbage collection interval in seconds. Default is 300.
gc_interval: 300
# adaptec_raid: yes
# alarms: yes
# am2320: yes
# anomalies: no
# beanstalk: yes
# bind_rndc: yes
# boinc: yes
# ceph: yes
# changefinder: no
# dockerd: yes
# dovecot: yes
# this is just an example
example: no
# exim: yes
# fail2ban: yes
# gearman: yes
go_expvar: no

# memcached: yes
# mongodb: yes
# monit: yes
# nginx_plus: yes

# squid: yes
# traefik: yes
# tomcat: yes
# tor: yes
# uwsgi: yes
# varnish: yes
# w1sensor: yes
# zscores: no
# temperature: yes
But nothing happens after reboot.
Could you tell me please, what I do wrong?
