Discovery uses the Horizontal Pattern probe to launch
patterns for horizontal discovery.
The Horizontal Pattern probe works with the Horizontal Discovery sensor to enable
Discovery to use patterns for discovery. When you see messages in the ECC Queue from this
probe, they appear with the ECC queue name Pattern Launcher, followed by
the name of the pattern. The probe contains a sensor named Horizontal Discovery
Sensor, which performs the actual updates of the CMDB based on identification
rules.If you create your own device or process classifier and you want to use patterns
for discovery, you must specify this
probe in the classifier record. You do not need to modify this probe or the
Horizontal Discovery sensor.
Splitting payload
When Discovery uses patterns to find certain devices
like load balancers, large amounts of data could be sent to the ECC Queue. To better handle
large amounts of data, the horizontal pattern probe can split the payload into chunks, and
then create multiple ECC Queue records.
Control how the MID Server splits payloads and
handles payloads using properties. See MID Server properties for more
information.
