Not seeing expected content in server/logs/valheim_server.log anymore.

Issue:

The only content I'm seeing in my valheim_server.log file is:
[ODIN][INFO] - Success, daemonized

I'd expect to see the same content or similar content to if I ran the docker container in the foreground, or ran docker-compose logs if it was daemonized. But, I'm not seeing that.

Up until 8 months ago I ran a docker instance for a small group of us playing together. I'd use that log file to parse for events and send notifications. Eventually, we finished with that world and moved on to other things. Over the past week or so, we've decided to start back up again. So I stood up another EC2 instance, provisioned it with scripts developed last time, and got things going.

I immediately saw an issue with Odin permissions, found the discussions in the issues here, and watched it get fixed. I figured that was related to the log issue I was seeing. Then it was just [ODIN][ERROR] - Error: unable to set group, errno 1.

But, while Odin is obviously happy with the logs now based on it's message, I'm still not seeing the log output I'm looking for.
I tried to turn on DEBUG_MODE because perhaps that's what I want, but no dice.

I looked for other disussions and issues related to logs as well and didn't see anything. I thought I'd ask here in case anyone has any ideas. I'm an old server guy who loves logs and scripting, and am open to the idea that perhaps there's a different approach to solve what I'm trying to do, monitor the server for events in real-time and take action on them.

My setup is an EC2 instance running the docker image. My redacted compose file is:

version: "3"
services:
  valheim2:
    container_name: newgrog
    image: mbround18/valheim:latest

Probably best to mention specifically, that the server runs fine otherwise. Totally playable, no issues. Thus making this a Q&A, and not Help, or an Issue.

i thought this error was fixed in update [ODIN][ERROR] - Error: unable to set group, errno 1. maybe i forgot to check it in. lemme check

[mbround18]

https://github.com/mbround18/valheim-docker/blob/main/src/odin/server/startup.rs#L27-L31 removed group check

That error was fixed. Totally fine now. And I was waiting for that before brining this up because it seemed related.

But all I'm seeing in it's place is [ODIN][INFO] - Success, daemonized and that's it... nothing else in the log, when daemonized or no.
If I tail that log file and stop and start the server I see it get truncated and the new line added. But no actual valheim server data in that log. Odin can obviously write to the log file, but it's not writing anything to it other than that that I've seen so far.

I've done quite a few restarts of the server, a play session or two, and nothing in that log. I've done that while watching the output running the container in the foregroud and see what I'm looking for, and daemonized, and docker-compose logs shows stuff, but it's not in valheim_server.log anymore.

Thanks for looking at this too, btw. I appreciate it.

Very strange on the logs, ill look into it :)

I see in that code where you are passing stdin and sterr, I'm no rustacean, but seems like that should work to me.

Thanks.
