Hi @alexm! You may run the following command on gitlab-runner to see the logs: journalctl -u gitlab-runner Note: You may want to replace “gitlab-runner” with the user, which is being used to run the gitlab-runner Answer from paramveer.singh on forum.gitlab.com

Troubleshooting GitLab Runner | GitLab Docs
If GitLab Runner is running as a service on Windows, it creates system event logs. To view them, open the Event Viewer (from the Run menu, type eventvwr.msc or search for “Event Viewer”). Then go to Windows Logs > Application. The Source for Runner logs is gitlab-runner.

The Failed Jobs tab only lists a summary. Please try the Jobs tab and click on the failed job there.

If the log doesn't contain enough details, add debug logging to your .gitlab-ci.yml file and run it again.

The logs for service go to syslog or in case of systemd-based runner you can get the logs by running:
journalctl -u gitlab-runner

To tail the logs : journalctl -u gitlab-runner | tail -100


find specific runner logs: 
 journalctl -u gitlab-runner | tail -100 | grep "runner-id"

The "background runner" is just running a command to start the runner. Just run that command from a terminal yourself if you want to watch it go.

More GitLab Runner Troubleshooting Tips
June 4, 2026 - I’ve been writing a lot lately about Continuous Integration and using GitLab Runner. It’s really nice when it works and it works 90% of the time, but issues do pop up occasionally. They can be a pain to troubleshoot. I previously wrote about how to run GitLabRunner as a regular user. You should all do that. If you are not, go do that now, you’ll thank me later. But there is more to troubleshooting than just that, so I thought I’d add some more tips here. The first tip is to always turn on build logs and unit test reports.

The logs for the gitlab-runner service go to syslog or in case of systemd-based system also to: journalctl -u gitlab-runner.

If you are talking about gitlab.com runners, you do not have access to the machines, try using your own runner if needed.

Sorry for asking a beginner question, I want to get the real-time logs while the pipeline is running, I saw the logs was generated on the gitlab node. How can I get them, so I can read it on after script before finishing the stage on the pipeline. I want to read it on gitlab runner container running the pipeline. gitlab ce on-premise.

You should ask this question in r/gitlab My only thought would be to use the GitLab API to pull the log contents.. however I'm not sure if runner tokens get access to all of the API so you might have to provide an access token and this idea just sounds crappy ;-) edit: grammar

https://docs.gitlab.com/ee/api/jobs.html#get-a-log-file Definitely would recommend reading documentation. I entered "gitlab api job logs" into google and this was the top search result. From there, I just scrolled down until I found an API endpoint for requesting logs.

You can declare an artifact for the log:

image: alpine

variables:
  GIT_SUBMODULE_STRATEGY: recursive

build:
  script:
    - apk add cmake
    - cd include/boost
    - sh bootstrap.sh

  artifacts:
    when: on_failure
    paths:
      - include/boost/bootstrap.log

Afterwards, you will be able to download the log file via the web interface.

Note that using when: on_failure will ensure that bootstrap.log will only be collected if the build fails, saving disk space on successful builds.
