# Console Log Commands

The log scope comes with several commands -- see [Log Scope](https://help.qlik.com/talend/en-US/esb-container-administration-guide/8.0/log-scope) for a full list.

For example, if you want to debug something, you might want to run the following commands:

```
>log:set DEBUG
... do something ...
>log:display
```

Note that the log levels set using the log:set commands are not persistent and will be lost upon restart. To configure those in a persistent way, you should edit the configuration file mentioned above using the config commands or directly using a text editor of your choice. The log commands have a separate configuration file: <RuntimeContainerPath>/etc/org.apache.karaf.log.cfg.

For more information about the logging system, see the site http://karaf.apache.org/manual/latest/#\_log.
