Symantec Management Platform (Notification Server)

How do the delta inventory policies work? Specifically if I have a computer resource missing data for a dataclass, would delta gather this information? Or would I need a full inventory ran to gather missing information? I wasnt sure if delta checked against what the agent said it had, or if checked against what the SMP server said it had, for that resource.

Thanks in advance.

then checks the results (.nsi files) against the previous inventory on the client (.bak files), sends the difference (delta) to the NS as an .nse, deletes the .bak files and renames the .nsi files to .bak for the next time.

A Full Inventory just deletes the .bak files first.

TECH28510 is currently offline, but this Google cache shows the original results:
Inventory for Windows will run a delta inventory by default, unless the /cleanbeforerun option is used in a policies command line. Exact copies of the latest .nsi files are created with a .bak extension. After new .nsi files are created by each of the inventory processes (aexauditpls.exe, aexmachinv.exe, and so on), the new .nsi files are compared against any preexisting .bak files from previous inventory runs. The collector will perform a byte-by-byte comparison of the new .nsi file and the corresponding .bak file. If any differences are found, the new NSI data is added to the NSE file and is sent to the Notification Server for loading into the database.

A delta inventory on a new computer functions identically to a full inventory, because no previous .nsi exists for comparison.  You can confirm this by capturing NSE's on the client or simply by running a Delta Inventory task on a new computer.

Does this answer your question?
