Tracking Disk Usage on the Application Block Device

This section demonstrates how to use Cloudera Manager to chart disk usage on the Application block device over time, and to create a trigger to notify cluster administrators when free space on the block device falls below a certain threshold.

The latter is particularly important because once the Application block device runs out of disk space, Cloudera Data Science Workbench will stop launching any new sessions or jobs. Advance notifications will give administrators a chance to expand the block device or cleanup existing data before Cloudera Data Science Workbench users run into any problems.
