MidServer Services Architecture
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.
The MID Server enables communication between a Servicenow Instance and the customer network |
It is a Java Application that runs as a Windows Service or a Unix Dameon |
It requires only an outbound connection on Port 443 |
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. |

#FireWall Ports |
|
- Local LAN inbound (from MID server IP to scanned IPs)
|
- Any/Any for Windows desktop firewall
|
- Access to admin share (e.g. C$)
|
- Allow 22, 80, 135, 161, 443, 445, 8585, 1024-65535
|
- May need additional allowed ports if targets not listening on default ports on scanned devices

Mid-Server Validation process
|
VALIDATE MID-SERVERS |
|
Navigate to MID Server > Servers. |
Open the new MID Server from the list of MID Servers. |
Under Related Links click Validate. |
The Set Initial Selection Criteria window appears if there are no records in the Supported Applications, IP Ranges, or Capabilities related lists. |
On the Set Initial Selection Criteria window, use the switches to enable or disable selection criteria for this MID Server: |
Allow ALL capabilities: Allow all capabilities for Orchestration and Event Management use this MID Server. |
Note: Service Mapping and Event Management alert aggregation and RCA, which used capabilities in previous releases, rely on the application for MID Server selection starting with the Istanbul release. |
Allow ALL applications: Allow all applications that use MID Servers use this MID Server. |
Allow ALL IP ranges: Make all IP ranges valid for this MID Server, meaning that it can target any IP address. |
Setting initial selection criteria |
|
|
If you click Cancel, the validation continues but none of the capabilities, applications, or IP ranges are added. |
Click OK. |
The Validated field on the dashboard is set to Validating, and then set to Yes after the validation completes. |
