SQL Server Audit action_id List

While reviewing some audit logs genereated in SQL Server 2008 auditing I came across a a few action_id values that were not completely obvious to me. I began the great google search in hopes of finding a table that mapped out this information and was somewhat unsuccessful. What I did manage to put together was a a query to determine what they all meant.

Select DISTINCT action_id,name,class_desc,parent_class_desc from sys.dm_audit_actions

The above query will list all the action_id’s and what they actually mean in the world of SQL.  In order to save time for everyone the trimmed down list is below.
