# Debugging
|
|
If the build logs do not provide enough detail on why a build may be failing, some other options exist to assist with troubleshooting.
|
|
|
|
## Runner Diagnostic Logs
|
|
Runner Diagnostic Logs provide additional log files detailing how the Runner is executing an action.
|
|
|
|
Each file contains different logging information that corresponds to that process:
|
|
* The Runner process coordinates setting up workers to execute jobs.
|
|
* The Worker process executes the job.
|
|
|
|
These files contain the prefix `Runner_` or `Worker_` to indicate the log source.
|
|
|
|
### How to Access Runner Diagnostic Logs
|
|
These log files are enabled by [setting the secret](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables) `ACTIONS_RUNNER_DEBUG` to `true`.
|
|
|
|
All actions ran while this secret is enabled contain additional diagnostic log files in the `runner-diagnostic-logs` folder of the [log archive](https://help.github.com/en/articles/managing-a-workflow-run#downloading-logs-and-artifacts).
|
|
|
|
## Step Debug Logs
|
|
Step debug logs increase the verbosity of a job's logs during and after a job's execution to assist with troubleshooting.
|
|
|
|
Additional log events with the prefix `##[debug]` will now also appear in the job's logs.
|
|
|
|
### How to Access Step Debug Logs
|
|
This flag can be enabled by [setting the secret](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables) `ACTIONS_STEP_DEBUG` to `true`.
|
|
|
|
All actions ran while this secret is enabled will show debug events in the [Downloaded Logs](https://help.github.com/en/articles/managing-a-workflow-run#downloading-logs-and-artifacts) and [Web Logs](https://help.github.com/en/articles/managing-a-workflow-run#viewing-logs-to-diagnose-failures).
