You say, "By the the end of this Part you should have enabled logging using the SQL Server log Provider, and also gathered the Names and IDs of your packages and tasks."
You do not provide in this first article how to use and set the suggested logging modes for Pre, Post, etc nor do you explain using SQL Server log Provider. Nor do you clearly explain where the Package ID tables would be nor how to find them. I suspect you are assuming that the Packages in use are stored in a database and not on the file system, but I cannot tell from your article.
Perhaps I missed the above descriptions in your article, and did you say which version of SSIS are you using as the basis of this article?
