Logging	Enable logging to inspect events while building your site.

Command line

Enable console logging with the --logLevel command line flag.

Hugo has four logging levels:

error

Display error messages only.

hugo --logLevel error

warn

Display warning and error messages.

hugo --logLevel warn

info

Display information, warning, and error messages.

hugo --logLevel info

debug

Display debug, information, warning, and error messages.

hugo --logLevel debug

{{< note >}} If you do not specify a logging level with the --logLevel flag, warnings and errors are always displayed. {{< /note >}}

Template functions

You can also use template functions to print warnings or errors to the console. These functions are typically used to report data validation errors, missing files, etc.

LiveReload

To log Hugo's LiveReload requests in your browser, add this query string to the URL when running Hugo's development server:

debug=LR-verbose

For example:

http://localhost:1313/?debug=LR-verbose

Then monitor the reload requests in your browser's dev tools console. Make sure the dev tools "preserve log" option is enabled.
