          What role do MID Servers play in populating CI data during Discovery?

Hello @Prathamesh45 

Purpose of MID Server is to access the Resources like network devices, servers etc in your Network.

Since ServiceNow is hosted in ServiceNow cloud they cannot access your resources, MID Server act as a layer to send the details to ServiceNow Instance.

Hi @Prathamesh45 ?

the MID server is hosted inside your company infrastructure and runs run as a broker between your ServiceNow instance and your company CIs

ServiceNow provides multiple ways to create Configuration Items (CIs), and one of the most common methods is through Discovery. Discovery relies on a MID Server, which runs within the organization’s network. The MID Server is a lightweight Java application that uses the Asynchronous Message Bus (AMB) to securely communicate with the ServiceNow instance.

Once CIs are reported back to the instance, ServiceNow uses the Identification and Reconciliation Engine (IRE) to uniquely identify each CI. Based on the IRE rules, the correct CI classes are determined, and the data is ingested into the CMDB accordingly.
