Shows docker containers but no usage on OVH Dedicated

[Gui13]

Hi,

I have a dedicated server at OVH, and the current release of CTOP seems to not work on it:

I can see my one container, but there's no mem/cpu/rx-tx working it seems, even though I'm using the container and top sees activity.

Uname -a:

Linux xxxx 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) x86_64 GNU/Linux

Processor is (there's 4 of them):

ctop version is:

wget https://github.com/bcicen/ctop/releases/download/v0.4/ctop-0.4-linux-amd64 -O ctop

If you need extra info, ask away.

Also, I didn't try compiling on premises, I used the release.

Thanks for the details; can you provide the output of docker version on the host server?

$ docker version
Client version: 1.6.2

Most likely you're on a very outdated server. I think about 1.11 (you're at 1.6) adds monitoring capabilities, somewhere around api 1.21-1.23. Also the kernel version is quite outdated, so most likely you're in for an upgrade, before you can use ctop.

Edit: keep in mind that docker somewhere from 1.10-12 also switched to a newer registry (v2). With your installation I don't even think you can pull new images from docker hub/etc. It's very old.

Damn. Default debian packaging. Thanks! You might add in your readme that you need docker v1.21 ?

I believe the minimum version requirement is 1.8; however, I'll need to do some changelog review to be sure.

According to the official docs at least, 1.18 API should already have the stats endpoint

https://docs.docker.com/engine/api/v1.18/

Most likely just the response contents are different and ctop runs into a load/parse error. I'm completely guessing here.
