Hi - Consider attending a Discovery Fundamentals class where you learn all the phases of Discovery (4) and how to build classifiers and custom Patterns.  Note: as of the Madrid (current) version of the DF class, creating custom probes/sensors is no longer taught.  This is because ServiceNow is moving away from Probes/Sensor and investing into Patterns only -- hence the latest class version does the same.  (prior DF class versions taught a mix of Probes/Sensors and Patterns)

Hope this helps?

Hi Dave,

Bit confused here. Patterns are used only for last 2 phases right.

If I wanted to do a port scan and classification of some device which is not covered OOB, then I need to make use of custom probe and sensor atleast for initial 2 phases right.

Hello Shanks,

So the idea is that, your pattern should take care of all the phases within itself. That way we move away from probes to patterns.

I found the following very helpful, you might want to try it too.

Yes, you're right. You can right the probes for first 2 phases.
