## Command line
Enable console logging with the `--logLevel` command line flag.
Hugo has four logging levels:
error
: Display error messages only.
```sh
hugo --logLevel error
```
warn
: Display warning and error messages.
```sh
hugo --logLevel warn
```
info
: Display information, warning, and error messages.
```sh
hugo --logLevel info
```
debug
: Display debug, information, warning, and error messages.
```sh
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.
{{< list-pages-in-section path=/functions/fmt filter=functions_fmt_logging filterType=include >}}
## LiveReload
To log Hugo's LiveReload requests in your browser, add this query string to the URL when running Hugo's development server:
```text
debug=LR-verbose
```
For example:
```text
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.
