Using workflow run logs

You can view, search, and download the logs for each job in a workflow run.

GitHub Actions is available with GitHub Free, GitHub Pro, GitHub Free for organizations, GitHub Team, GitHub Enterprise Cloud, GitHub Enterprise Server, and GitHub One. GitHub Actions is not available for private repositories owned by accounts using legacy per-repository plans. For more information, see "GitHub's products."

You can see whether a workflow run is in progress or complete from the workflow run page. You must be logged in to a GitHub account to view workflow run information, including for public repositories. For more information, see "Access permissions on GitHub."

If the run is complete, you can see whether the result was a success, failure, canceled, or neutral. If the run failed, you can view and search the build logs to diagnose the failure and re-run the workflow. You can also view billable job execution minutes, or download logs and build artifacts.

GitHub Actions use the Checks API to output statuses, results, and logs for a workflow. GitHub creates a new check suite for each workflow run. The check suite contains a check run for each job in the workflow, and each job includes steps. GitHub Actions are run as a step in a workflow. For more information about the Checks API, see "Checks."

Note: Ensure that you only commit valid workflow files to your repository. If .github/workflows contains an invalid workflow file, GitHub Actions generates a failed workflow run for every new commit.

Viewing logs to diagnose failures

If your workflow run fails, you can see which step caused the failure and review the failed step's build logs to troubleshoot. You can see the time it took for each step to run. You can also copy a permalink to a specific line in the log file to share with your team. Read access to the repository is required to perform these steps.

In addition to the steps configured in the workflow file, GitHub adds two additional steps to each job to set up and complete the job's execution. These steps are logged in the workflow run with the names "Set up job" and "Complete job".

For jobs run on GitHub-hosted runners, "Set up job" records details of the runner's virtual environment, and includes a link to the list of preinstalled tools that were present on the runner machine.
