ServiceNow - SCCM Integration and Cisco Meraki Plugin VS ServiceNow ITOM Discovery - What is the difference?
ServiceNow SCCM plugin is an extension of ServiceNow which can go into your SCCM database via MID server and bring SCCM-managed CIs like OS and Software to your CMDB.
ServiceNow Meraki plugin is also a similar extension that can be used to bring your Cisco Meraki CIs into CMDB. But this has a slightly different approach in the integration than the SCCM plugin as it uses REST web services to make the connection.
Both of these plugins can bring CI data to ServiceNow but are capable of doing this other than that. With the plugins, you get a few dashboards that are really useful but have limited functionalities specific to each technology.
ServiceNow Discovery tool also brings the CI data of your organization to ServiceNow. From the first look, functionality seems very similar to the above-mentioned plugins hence most of the organizations who have both SCCM and Meraki plugging installed often think implementing discovery which costs them for licenses is duplicate work.
But it's not ...
The Discovery tool is an enhanced middleware package that can go into your network and monitor all kind of devices you permits it to watch and bring that data into ServiceNow CMDB. As it has been plugged into the ITOM module it contains enhanced capabilities in reporting and can be directly plugged into PA dashboards. This part of Discovery we often call horizontal discovery capabilities.
But there is another interesting part which we call top-down discovery which often refers to Service Mapping which allows you to map service-specific devices. This is obviously not included in any of the plugins mentioned above but only in the ITOM Discovery.
