title: Enabling debug logging
shortTitle: Enable debug logging
intro: >-
  If the workflow logs do not provide enough detail to diagnose why a workflow,
  job, or step is not working as expected, you can enable additional debug
  logging.

{% data reusables.actions.enterprise-github-hosted-runners %}

These extra logs are enabled by setting secrets or variables in the repository containing the workflow, so the same permissions requirements will apply:

• {% data reusables.actions.permissions-statement-secrets-variables-repository %}
• {% data reusables.actions.permissions-statement-secrets-environment %}
• {% data reusables.actions.permissions-statement-secrets-and-variables-organization %}

For more information on setting secrets and variables, see AUTOTITLE and AUTOTITLE.

Additionally, anyone who has access to run a workflow can enable runner diagnostic logging and step debug logging for a workflow re-run. For more information, see AUTOTITLE.

Enabling runner diagnostic logging

Runner diagnostic logging provides additional log files that contain information about how a runner is executing a job. Two extra log files are added to the log archive:

• The runner process log, which includes information about coordinating and setting up runners to execute jobs.
• The worker process log, which logs the execution of a job.

1. To enable runner diagnostic logging, set the following secret or variable in the repository that contains the workflow: ACTIONS_RUNNER_DEBUG to true. If both the secret and variable are set, the value of the secret takes precedence over the variable.
2. To download runner diagnostic logs, download the log archive of the workflow run. The runner diagnostic logs are contained in the runner-diagnostic-logs folder. For more information on downloading logs, see AUTOTITLE.

Enabling step debug logging

Step debug logging increases the verbosity of a job's logs during and after a job's execution.

1. To enable step debug logging, set the following secret or variable in the repository that contains the workflow: ACTIONS_STEP_DEBUG to true. If both the secret and variable are set, the value of the secret takes precedence over the variable.
2. After setting the secret or variable, more debug events are shown in the step logs. For more information, see AUTOTITLE.
