CPU Temperature and CPU Load error

Problem/Question

I have installed Netdata Agent on two different Qnap NAS, a TS-653A (v1.35.0-54-nightly) and a TS-653D (v1.35.0-256-nightly).
In both cases to install Netdata Agent I used ‘docker compose’ via the Container Station.
The CPU temperature values provided by ‘sensors.coretemp-isa-0000_temperature’ tend to be wrong for both NAS.
In the case of the TS-653A, the CPU temperature value is a few degrees higher.
Instead for the TS-653D the data of ‘sensors.coretemp-isa-0000_temperature’ are decidedly higher than those indicated by the Qnap operating system (QTS 5.0.0.2055). Sometimes even 13 or 15 degrees. The ‘CPU load’ data is also two to three times higher than that provided by the operating system.

Relevant docs you followed/actions you took to solve the issue

I have not undertaken any initiatives

Environment/Browser/Agent’s version etc

Netdata Agent v1.35.0-54-nightly on Qnap TS-653A via docker compose
Netdata Agent v1.35.0-256-nightly on Qnap TS-653D via docker compose.
E.G. Qnap TS-653D docker compose below:

version: '3'
services:
  netdata:
    image: netdata/netdata:latest
    hostname: QNAP-TS653D # set to fqdn of host
    environment:
      - DO_NOT_TRACK=1
    ports:
      - 19999:19999
    restart: unless-stopped
    cap_add:
      - SYS_PTRACE
    security_opt:
      - apparmor:unconfined
    volumes:
      - ./netdataconfig/netdata:/etc/netdata:rw
      - netdatalib:/var/lib/netdata
      - netdatacache:/var/cache/netdata
      - /etc/passwd:/host/etc/passwd:ro
      - /etc/group:/host/etc/group:ro
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
volumes:
  netdatalib:
  netdatacache:

What I expected to happen

I would like to have the correct data

Just to give it a try I added the following line to the docker compose.

- /etc/os-release:/host/etc/os-release:ro

Also I added the following to the ‘environment’ section

- DOCKER_USR=dockeruser

Below you can find my new docker compose

version: '3'
services:
  netdata:
    image: netdata/netdata:latest
    hostname: QNAP-TS653D # set to fqdn of host
    environment:
      - DOCKER_USR=dockeruser
      - DO_NOT_TRACK=1
    ports:
      - 19999:19999
    restart: unless-stopped
    cap_add:
      - SYS_PTRACE
    security_opt:
      - apparmor:unconfined
    volumes:
      - ./netdataconfig/netdata:/etc/netdata:rw
      - netdatalib:/var/lib/netdata
      - netdatacache:/var/cache/netdata
      - /etc/passwd:/host/etc/passwd:ro
      - /etc/group:/host/etc/group:ro
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /etc/os-release:/host/etc/os-release:ro
volumes:
  netdatalib:
  netdatacache:

I don’t think it helped.

I note that if I set the variable ‘./netdataconfig/netdata:/etc/netdata:rw on’ ro ‘’ Netdata Agent does not start due to lack of write permissions. But I think this is normal

At the following link you can find the Netdata Agent startup log.

Just to try a few more I updated the 1.36.0 image on the Qnap TS-653D.

Unfortunately, the problem of ‘CPU Temp’ and ‘CPU Load’ values higher than reality is still present.

I attach the log of the startup phase that I managed to copy (accessing the log is not easy with the Qnap Container Station).

Netdata Agent 1.36.0 startup on Qnap TS-653D

I am also attaching the values of ‘/ api / v1 / info’

Netdata Agent 1.36.0 /api/v1/info

Maybe it’s a silly problem related to the configuration of the ‘docker compose’ or to the permissions to access the container.
Unfortunately, I am not experienced enough to identify the problem.

Thanks for your time and attention.
