SMART is not displayed on a web page but available in a container through smartctl #2916

v-bulynkin · 2024-08-11T10:13:07Z

Hello dear sir,

I'm trying to display the SMART information from Docker container. What I've done:

Enabled SMART plugin by disable=False in glances.conf.
Added the following options to the Glances service in docker-compose.yml:

    privileged: true
    devices:
      - /dev/nvme0n1:/dev/nvme0n1

After that:

"SMART disks" on a web page is empty
docker exec glances glances --stdout smart is empty too:

docker exec glances smartctl -a /dev/nvme0n1 works well:

Why the SMART plugin can't show the information? Does it support NVMe drives?

The text was updated successfully, but these errors were encountered:

Hi @v-bulynkin

the Smart plugin is disable by default in the Glances configuration file.

You can enable by editing your glances.conf file (/etc/glances/glances.conf inside the container):

[smart]
# Documentation: https://glances.readthedocs.io/en/latest/aoa/smart.html
# This plugin is disabled by default
disable=True

or via the command line:

docker exec glances glances --enable-plugin smart

Keep us inform.

v-bulynkin · 2024-08-11T17:29:33Z

I wrote that I enabled it in the first message:

Enabled SMART plugin by disable=False in glances.conf.

I mount the glances.conf file in docker-compose.yml the following way:

    volumes:
      - ./glances/glances.conf:/etc/glances/glances.conf

Is it not enough?

RazCrimson · 2024-08-11T19:10:44Z

@v-bulynkin
That should be enough, but glances looks for paths in multiple locations. So if possible, could you just give the command line variant a try, so that atleast it works when enabled explicitly?

docker exec glances glances --enable-plugin smart

If that works, then could you just try running glances in debug mode (-d flag) and check the start of the logs?

Should be present at ~/.local/share/glances/glances.log inside the container

v-bulynkin · 2024-08-12T14:24:26Z

I have this configuration now in docker-compose.yml:

  glances:
    image: nicolargo/glances:dev
    container_name: glances
    hostname: example.com
    restart: unless-stopped
    pid: host
    privileged: true
    devices:
      - "/dev/nvme0"
    environment:
      GLANCES_OPT: "-w -d --enable-plugin smart"
    volumes:
      - ./glances/glances.conf:/etc/glances/glances.conf
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /etc/os-release:/etc/os-release:ro
    labels:
      - "traefik.enable=true"
      - "traefik.http.services.glances.loadbalancer.server.port=61208"

It's perhaps an issue concerning the read rights on the /dev/nvme0n1 file. Inside your container, glances user should be allowed to read this file.

I have the same issue on my laptop (running Glances not from a container):

glances

No smart info displayed

sudo glances

nicolargo · 2024-08-17T08:24:05Z

Note for Glances developer.

A mode exist to run PySmart in sudo:

>>> from pySMART import DeviceList
>>> from pySMART import Device
>>> sda = Device('/dev/sda')
>>> sda
<UNKNOWN INTERFACE device on /dev/sda mod:None sn:None>
>>> devlist = DeviceList()
>>> devlist
<DeviceList contents:
>
>>> from pySMART import SMARTCTL
>>> SMARTCTL.sudo = True
>>> sda = Device('/dev/sda')
>>> sda
[sudo] password for user:
<SAT device on /dev/sda mod:ST10000DM0004-1ZC101 sn:ZA20VNPT>
>>> devlist = DeviceList()

<SAT device on /dev/sdd mod:ST10000DM0004-1ZC101 sn:ZA2215HL>

But password should be enter...

...
[sudo] password for user:
...

or sudoers file configure correctly...

I'm running glances (not the current version) on a Fedora server as root and seeing similar output - just formatted slightly differently. I'll try testing a newer version:

Testing pySMART directly:

root@host1:~# python3

I figured there might be some SELinux interference but there are no log entries from setroubleshootd corresponding with the time this is being tested. Also of course, executing pySMART directly does seem to work.

Running the current version I get good output:
