Inventory and Throttling

Inventory is a disk and can be a CPU intensive task and this has nothing to do with full or differential Inventory, both scan the complete disk (is no extra exclusions are made)

There there are some techniques to take off the load.

CPU throttling

For software/file inventory task you can choose between Low, Normal, High and Very High priority under “Set inventory process priority” (Run Options tab of Advanced settings). Priorities correspond to the following settings (“nice” options for UNIX/Linux/Mac):

Priority

Windows

Linux

Unix

Macintosh

Low

25%

10             

30

10

Normal

50%

0          

20

0

High

75%

-10

10

-10

Very High

100%

-20

0

-20

This can be overridden (Windows only) using the “Override inventory process priority” option

If you select to override a good comparison for Windows would be :

Priority Files Wait for (ms)
Low 150 60
Normal 250 50
High 350 40
Very High 450 20

Bandwidth Throttling or Fuzzy Logic (Windows Only)

The AeXRunContol does no longer exist, but there is a setting called “Evenly distribute sending inventory over X hours” (aka fuzzy logic). It is located on Run Options tab of Advanced settings.
