Discovery - Custom SNMP Probe Classify-Identify Stage

[Bob Mullineaux]

I am trying to develop a custom SNMP Probe to extract information for devices using enterprise OIDs.  The probe works great as an Exploration Probe but want to extend it to become a Classify/Identify Probe and does not seem to working.  The idea is to get the serial number from the enterprise OID (which I can do), but use it as part of Identification for the CI i.e. update if Hardware ID rule matches, create if not.

I see many probes such as SNMP - Netscaler - Identity Multiprobe that is like what I think I am trying to do but have had no success in mimicking that approach using APIs such as SnmpIdentityInfoParser, IDSensorUtil()  or the Multisensor  DiscoveryIDSensor({});   I cannot locate documentation or other reference materials.

Dependent on the class you would do this in a pattern step, are you creating a whole new classifier for this work or something existing?

Hi Doug,

I am not using a Pattern, rather resorting to the Probe/Sensor methodology.  Also, not creating a new or custom Class, rather just a Router or Switch.   I am trying to do something similar to the SNMP - Netscaler - Identity Multiprobe that exists out of box but cannot location documentation or references to the APIs forementioned.

Ahh, yes. Reads as if you may have not migrated to patterns from probes yet.. You want to do that first for sure. As to your original ask, Im going to say you are going down a dead end. Our SNMP work was a confusing mix of java classes and javascript probes/sensors and its always been near impossible to manipulate at granular levels like this.

Id again go the pattern route as you have much better control and manipulation over the data in its end to end processing.

Hi Doug,

I appreciate your advice but assuming probes/sensors are still supported by ServiceNow (which I believe they are) I am looking for something a bit more substantial.  I am on San Diego and using current store patterns and never had to migrate any legacy probes on this account.  Thanks!
