Before you post: Your responses to these questions will help the community help you. Please complete this template if you’re asking a support question.  
**Don’t forget to select tags to help index your topic!**

**1. Describe your incident:**  
Running graylog in docker. Followed docker installation process here: [Docker - Installing Graylog](https://docs.graylog.org/docs/docker). No inputs start. “Request to start input failed, Check your graylog logs for more information”

**2. Describe your environment:**

- OS Information:  
Docker running on Ubuntu 21.10

- Package Version:  
Graylog 4.2.5+59802bf

- Service logs, configurations, and environment variables:  
GRAYLOG\_PASSWORD\_SECRET  
GRAYLOG\_ROOT\_PASSWORD\_SHA2  
GRAYLOG\_HTTP\_PUBLISH\_URI  
GRAYLOG\_HTTP\_EXTERNAL\_URI

**3. What steps have you already taken to try and solve the problem?**  
verified correct environment variables. In error message it indicates to look for logs, but I cannot find them within the docker container.

**4. How can the community help?**  
Being able to find the Graylog logs in the docker container indicated in the error message would be good start. Without that I do not have much information as to whats actually wrong.

Hello && Welcome @icsj2007

Ill be honest, I’m not good with Docker but I maybe able to help troubleshoot this issue with you.

This would help, what i found about GL Docker was from [here](https://stackoverflow.com/questions/39998496/where-are-the-log-files-located-in-the-graylog-server-docker-container)

And this…

> Hey there, this document on Docker’s site ([Syslog logging driver | Docker Documentation](https://docs.docker.com/config/containers/logging/syslog/)) describes configuring the syslog logging driver for Docker. If you configure Docker to point at a Graylog deployment running a syslog input, then getting Docker logs into Graylog is fairly trivial.

And I ran into this forum for Docker.

I believe if you can find your **log4j2.xml** ( Should be in your Graylog Directory) this should point where your log files are.

As for your Elasticsearch logs with Docker, I have found this. It may help later on.

> Hi @Petr.Simik To get Elasticsearch write the logs to file you either need to do some hacky stuff with docker and the command parameters or modify the log4j2.properties file. I advise you to check out the following site: ...

Normally your Graylog log files would be located in ` /var/log/graylog-server`
