System Monitoring - How does yours look?

Thanks. i installed hacs package ,

The Monitor Docker allows you to monitor Docker and container statistics and turn on/off containers. It can connected to the Docker daemon locally or remotely.
should work , but no idea how

If you are running Home Assistant in a container you need to give access to the socket. Add the following volume to your home assistant container:

 -v /var/run/docker.sock:/var/run/docker.sock

No , i have a pi4 running HA , and a synology running all the dockers.
So i need to retreive the data via lan.
Another point you might help , I have an Odroid N2+ which runs coreelec , i got the temperature with this ssh script , i would get also RAM and CPU usage , is there a way to get them as a % ?
sorry and thanks for your help

  - platform: ssh
    host: 192.168.xx.xx
    username: xxx
    password: xxx
    name: Coreelec CPU Temperature
    command: cat /sys/class/thermal/thermal_zone0/temp
    unit_of_measurement: "°C"
    value_template: >-
      {%- set line = value.split("\r\n") -%}
      {{ (line[1]|int / 1000) | round(1) }}

I assume the dockers on your Synology are not the Home Assistant docker containers or are they?

If you want to track remote docker containers, you need to setup a docker socket proxy like this one on the remote machine.

This is going to be a really advanced stuff to do for me
No idea where to start from , because docker on synology have no command lines.
Let’s see

Install the prixy docker container on the NAS, then try to connect to it from the Pi with

docker -H tcp://ip-of-the-nas:2376 ps

Or just add the flag to the docker daemon start up

ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock

$ docker container run \
    -d --privileged \
    --name dockerproxy \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -p 127.0.0.1:2375:2375 \
    tecnativa/docker-socket-proxy

ok… where should i run this?

Someone just liked my old post. Obviously I wasn’t done. I have replaced my system monitoring page with a system monitoring dashboard as it was impossible to fit it all in the one view.
