## Manage Log Files

You can gather log files about your Appliance Controller, which are then stored in the /var directory. You can also create a support bundle of these log files and send them to Quantum support to help diagnose any issues with your system.

Gather Log Files

2. Enter:

   supportbundle create

   The support bundle file appliance_controller_auto_support.sh.tar.bz2 is placed in the /var directory.

   Example:

   > supportbundle create

   Gathering support logs...

   Finished support package creation /var/appliance_controller_auto_support.sh.tar.bz2 (155 KB)Done.

Create and Email a Support Bundle

2. Enter:

   supportbundle send <email_address>

   The parameter is:

   `<email_address>` | The email address of the Quantum Support representative.

   Example:

   > supportbundle send jane.doe@quantum.com

   Gathering support logs...

   Finished support package creation /var/appliance_controller_auto_support.sh.tar.bz2 (155 KB)

   Emailing support package...

   Note: The `supportbundle send` command gathers the same logs and files as the `supportbundle create` command.
