This script is used to reanalysis dimensional data created by analysis plugins. Reanalysis is automatically performed when you install a new analysis plugin that does not change its defined attributes.

If you have installed a new analysis plugin, you may need to run this script. Refer to the installation documentation for that particular analysis plugin.

=== Full Analysis ===

This means a complete reanalysis of the dimension, including its primary nodes. This involves reconstructing the original logfile to some degree from the database. A full analysis cannot be run on dimensions that define their primary fields to be logfile fields. If a full analysis cannot be run, a partial analysis will be run instead.

=== Partial Analysis ===

This only reanalyzes the attributes of a dimension based on the primary nodes of the dimension. This type of analysis is generally much faster than a full analysis.
