I have the same problem.

New user of portainer, clicked on stats tab and got error as above. No stats shown.

Plain install of HassOS on RPI 3b+ 0.82

[tarbax]

same problem here.
latest hassio (resinos) on intel nuc

[turricansi]

i have the same problem

[lweberru]

the issue here. I get this also within command line executing a "docker top" command:

docker top homeassistant
Error response from daemon: Error running ps: exit status 1

[tboyce021]

Mine tells me

ps: ps: invalid option -- 'e'

Edit: Maybe somewhat related to portainer/portainer#616. The reporter there was apparently able to set the arguments with a Docker image. Perhaps something similar would work here?

[frenck]

Works in upcoming version:

[tboyce021]

Should this work in 0.5.0? I just tried and still get the same error.

[frenck]

it should, as per screenshots above.

Could you please provide me with your system details? (shown in the startup of the add-on, in the logs).

[frenck]

re-opening issue to see what @tboyce021 comes up with.

[tboyce021]

Mine is actually probably a HassOS issue. I just thought to try it on the host itself and get the same ps: ps: invalid option -- 'e' error from docker top homeassistant. Here is my info though:

 Add-on version: 0.5.0
 You are running the latest version of this add-on.
 System: HassOS 2.11  (amd64 / qemux86-64)
 Home Assistant version: 0.90.2
 Supervisor version: 152

Edit: This is using the VMDK with Proxmox on a NUC.

[lweberru]

still don't work with 0.5.0 (same error as before)

Here what I get logging into portainer itself via console:

[frenck]

Makes sense, the daemon does this on the host level, so this indicates the ps command on the host is more limited. Probably caused by busybox, which runs on HassOS, which has more limited functionality compared to the procps-ng version.

[tboyce021]

Sounds like this isn't going to be fixed on HassOS. Is there a way to make Portainer use the HassOS API or is this just going to remain broken for HassOS?

[tboyce021]

I'm not sure the HassOS API is sufficient for this anyway. I only see a way to get stats for the supervisor, HA, and add-ons, but I don't see a way to get stats for any container installed outside of that (i.e. using Portainer itself).

[tomlut]

Any idea who we could ask in the dev team about adding the ps command to HassOS?

This is a valuable tool for tracking down excessive resource use.

[TonyApuzzo]

HassOS uses buildroot to configure the system. It should be a relatively simple matter of tracking down which buildroot package contains the full ps and friends and adding it to a configuration file and rebuilding HassOS. If there is already a ps linked to busybox then will have figure out how to not have them conflict.

I may have some time this weekend to do a sample build of HassOS and see if that addresses this issue.

Disclaimer, I'm not a core dev and have little to no influence. But, if it works I will create a pull-request and see if it is accepted.

[tboyce021]

FYI, it does have ps but it comes from busybox and doesn't support the -e flag that Portainer apparently uses.

[TonyApuzzo]

I built the work-in-progress HassOS dev branch (3.1) with PROCPS_NG enabled and that does seem to fix portainer stats:

I will create a PR in HassOS and see if it goes anywhere.

UPDATE: home-assistant/operating-system#398

[TonyApuzzo]

The pull request with the fix was accepted into the dev branch for HassOS 3.1 -- I do not know how long it will be before the 3.x branch goes live for general users, but it will eventually be in the base.

[lweberru]

Just updated HASSOS to Release 2.12. And now it is really working. Well done!

[tomlut]

Confirmed. Nicely done.

[frenck]

Nice! Closing issue! 👍
