# Manage protocols debug level using the GUI
The Protocols Debug Level section displays the debug level for the S3 and NFS protocols only (the SMB debug level is not shown). You can change the debug level only for the configured protocols.
Using the GUI, you can:
* [Update S3 debug level](#update-s3-debug-level)
* [Update NFS debug level](#update-nfs-debug-level)
* [Update SMB debug level](#update-smb-debug-level)
{% hint style="info" %}
Once the container is restarted, the log verbosity level reverts to its default.
{% endhint %}
