Inventory Update Reporting Interval

• Microsoft Systems Management Server versions 1.0, 1.1 and 1.2

SUMMARY

When an inventory agent produces an inventory, the Site Server checks for changes and only pass through inventory data when a four-day timeout occurs, unless the changes are found outside the Identification Group and Workstation Status Group.

MORE INFORMATION

This can result in a machine inventory that only has changed attributes for Last Hardware Scan or Last Software Scan (indicating a routine scan time and no changes to the actual inventory). However, this inventory will not be posted to the database for four days.

This is by design and is intended to minimize the number of delta MIF transactions. A delta MIF is normally generated by the Inventory Processor each time it processes a machine inventory. It compares the last time a delta was forwarded to Inventory Dataloader to its four-day timer, and may block redundant deltas. For this reason, even if machine name, domain name, or any other item contained in the Workstation Status or Identification groups have changed, it takes four days for these changes to posted in the database (assuming a logon/inventory is made each day.)

A machine may not appear to have its Last Hardware Scan or Last Software Scan times up to date with the last time an inventory was actually taken. If you want greater accuracy, and are willing to accept increased system overhead, modify the following registry entry:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Components
      \SMS_INVENTORY_PROCESSOR\Inventory Update Reporting Interval (Days).
