## Log File Bundles

The Appliance Controller allows you to create a log file bundle, which is saved as a a tarball file and stored in the /var directory on the server. You can also create a log file bundle tarball and email the file to Quantum support in one step directly from the Appliance Controller. The log file bundle can help support to diagnose issues with your system.

2. At the prompt, enter the following:

   supportbundle create

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

   Example:

   > supportbundle create
