Docker Stats Nonexistant

[TheOtterslider]

Description

Perhaps I just can't figure it out, but from the sample graphs I've seen, the docker stats should "just" appear. Here's what I've done:

1 - installed Beszel server on 1 machine. It works, I can connect, and see data. I'll refer to this machine as my BServer later.
2 - installed the Beszel agent on another machine. This machine is my "server" and runs probably 2 dozen docker containers. This machine is what I'll reference as Server below.

Both of these installs are "binary" installs and everything appears working. On the BServer, I see stats for the the Server. Things update. But there's no stats about docker.

Reading issue 484 (#484), I've checked the group membership. It's a member of the docker group:

root@server:~# groups beszel
beszel : beszel docker

Reading issue 144 (#144), I'm not running on a pi but am using debian 12. When I run docker stats, I see memory data for my containers listed

I've read the common problems doc (https://beszel.dev/guide/common-issues)
docker on my server reports it's version 27:

And I've already mentioned I've checked the docker stats command.

I've checked /var/log on my Server, but don't see any logfile for Beszel there.

What else should I check?

OS / Architecture

linux/amd64

Beszel version

0.9.1

Installation method

Binary

Configuration

No response

Hub Logs

none shown

Agent Logs

I will provide these if you can tell me how.  I can't figure out how, from the docs, to increase the log-level.

For debug logs, try running the binary directly with some temporary options:

PORT=44555 KEY="..." LOG_LEVEL=debug /opt/beszel-agent/beszel-agent

Are you able to get container info via curl from the host?

curl --unix-socket /var/run/docker.sock http://localhost/containers/json

[TheOtterslider]

Actually, it works just fine. I get back what appears to be a JSON object with information about my containers.

[TheOtterslider]

PORT=44555 KEY="..." LOG_LEVEL=debug /opt/beszel-agent/beszel-agent

When I run that, I do get an error. Here's the text:

ERROR Error getting container stats err="CONTAINER_NAME - no memory stats - see #144"

I went ahead and had another look at issue 144. I ran the command and it looks like it should work

root@server:# docker info | grep -i cgroup
Cgroup Driver: systemd
Cgroup Version: 2
cgroupns

Can you check that the API is returning valid data for your containers?

Use docker ps to list containers, then copy the container's ID. (Pick a container that is showing up in the agent error logs.)

Then use curl to make a request to the API (replace d07d19594b6e with your container ID):

curl --unix-socket /var/run/docker.sock -H "Content-Type: application/json" "http://localhost/containers/d07d19594b6e/stats?stream=0&one-shot=1"

Post the response here please, and also what docker ps says in the CREATED and STATUS columns for the container.

[TheOtterslider]

I'm sorry for the slow reply. Had an emergency come up.

There was only 1 container listed in the agent error logs. When I started looking into it more, it turns out that container wasn't working right anyway.

I used docker commands to stop the container and reran the binary directly (as above). I don't see any lines displaying an error any more. I've restarted the Beszel service and I'll let it run through the afternoon to see if I get docker stats.

[TheOtterslider]

Just an update. After letting this soak for a few days, I still haven't got docker stats

running the binary in debug mode yields no errors.

Just for grins, I went out and removed it from the server and re-added it. No docker stats.
