Collecting Delta Values

When collecting the hardware and software inventory information from the computers, the asset management agent reports only the differential (delta) values by comparing the previous scan results and the current scan results. The agent first collects the entire inventory and then compares the results with the previous scan results (available in the bak directory). It creates a DIF file and saves the difference. This DIF file is placed in the collect area of the scalability server which is then processed by the engine for updating the database. This reduces network traffic and improves the engine performance as there are fewer records to be moved over the network and processed by the engine.

By default, the agent sends only the delta values. However, you can instruct the agent to send all the collected values to the scalability server. This is called re-collecting the inventory

Note: The agent does not send delta values in case of signature scanning.
