Service Mapping MID Server Selection

[Chaitanya86]

Team,

we are doing service mapping. We have 4 MID servers according to DC & Application Servers are also divided DC wise.

When we do application mapping in sys_properties we have to define specific MID server & do mapping.

Whats the best way to configure , so it can take appropriate MID server while doing service mapping.

Hi @Chaitanya86 ,

Service Mapping selects a MID Server using the following algorithm:

• Service Mapping chooses the MID Server whose selection criteria best match the parameters of the discovery request.
• If there are no MID Servers with matching selection criteria, Service Mapping chooses the default MID Server.
• If there are no MID Servers with matching selection criteria or default MID Server, Service Mapping cannot start the discovery process.

While by default Service Mapping uses this algorithm in all deployments upgraded from Istanbul or Jakarta, it can support both new and legacy algorithms for selecting a MID Server. For more information, see the Choose MID Server selection algorithm.

MID Servers have the following mandatory selection criteria that Service Mapping uses to choose the relevant MID Server:

• Application — defines what application a MID Server works with. Set it to Service Mapping to reserve this MID Server exclusively to Service Mapping discovery requests. Alternatively, set it to ALL to allow any ServiceNow application to use this MID Server.

• Capability — defines the network capability. For Service Mapping, set this parameter to ALL or any combination of SSH, WMI, SNMP, and Cloud Provisioning and Governance. See Configure MID Server capabilities.

• IP range — limits the operation of this MID Server to this IP range. Service Mapping does not choose this MID Server for a discovery request whose endpoint is outside this IP range. See Configure an IP address range for the MID Server.

Conceptually It works like 

--> Mid Server Capability Must be Set as Service Mapping or ALL 

--> The endpoint IP address used for Service Mapping  must fall within the IP range that you configure on the MID Server

Hope This helps.
