Discovering and Inventorying Devices 41
To an extent, the more threads that run in parallel, each communicating to a
different device, the faster is the discovery; barring overall high network
congestion or latency. The discovery process, by default, allows a maximum of
32 threads to run in parallel (or concurrently) at any one time for discovery.
To control the number of parallel threads executing, move the discovery
throttle control either left or right. When set at the maximum, 32 parallel
threads are actually allowed to run. If the throttle is at 50%, only 16 threads
are allowed to run at any one time.
As the discovery service is optimized for parallel threading operations, the
system can utilize more system resources even at the same throttle setting. It is
recommended that you monitor the system resources so that a satisfactory
trade-off is made between discovery speed versus system resources available for
OpenManage Essentials. Lowering or increasing the throttle depends on the
system it is running on and the available resources. Note that the discovery
service may take up to several minutes to adjust to a new throttle setting.
NOTE: For minimal discovery times on medium to large size networks (several
hundred to several thousand devices), it is recommended that you install
OpenManage Essentials services on a multi-processor system.

Inventory Speed slider control
—This control acts much like the
discovery throttle, controlling the number of threads that are used
during an inventory cycle. By default, there are a maximum number of
32 threads dedicated to performing the inventory process - the throttle
controls the number of threads are actually used.
NOTE: Each tick on the throttle control equals 10% and the range is from 10%
to 100%. The inventory throttle is set at 60% by default.
