MIdServer Services Requirements
The Management, Instrumentation, and Discovery (MID) Server is a Java application that runs as a Windows service or UNIX daemon on a server in your local network. The MID Server facilitates communication and the movement of data between a ServiceNow instance and external applications, data sources, and services.
Windows server: To discover Windows-based servers, run Service Mapping patterns, or execute Orchestration commands on Windows devices, the MID Server must be installed on a Windows server. The MID Server supports all Windows Server 2008, 2012, and 2016 editions, virtual machines, and 64-bit systems. Note: .NET Framework version 3.5, 4.0, 4.5, 4.6, or 4.7 is required for Service Mapping support and for Windows pattern-based discovery. |
