At AdminCamp last week, I talked about how to get the count of all files in the DAOS repository and it’s overall size using some batch programming in Windows and LINUX.

As an alternative I proposed to use the console command “show dir -xml” to return an xml representation of the properties of all applications in the Domino data directory.

I found some code by Julian Robichaux that does the parsing of the XML structure. I’ve stripped out the relevant code snippets and put together a script lib to get the DAOS Object count and the overall size of all DAOS Objects.

The code writes a summary of these values to a database. You can use this data to create nice looking charts and graphs.

Here is the code:
