Readiness of MID Server to Implement Service Mapping module

[Pranita Bahugun]

Hello everyone,

We’re in the process of implementing Service Mapping in our environment, and I’d like to ensure our MID Server is fully prepared for this purpose. I’m reaching out to gather a comprehensive checklist or best practices from those who’ve already implemented Service Mapping successfully.

Specifically, I’m looking to understand:

1. What capabilities or roles should the MID Server have enabled ?

2. Any particular network firewall ports or protocols that should be open?

3. Minimum hardware/resource requirements for the MID Server in a Service Mapping context?

4. Required user credentials for deep process and port discovery?

5. Should the MID Server be placed in a specific zone or subnet to discover critical application layers and interdependencies?

6. Are there specific logs, configurations, or permissions we should validate ahead of time?

7. Any recommendations on scalability if multiple maps or heavy discovery loads are expected?

If there’s any official documentation or community insight you’d recommend for production hardening the MID Server before launching Service Mapping, please share! Appreciate your input.

Thanks in advance,

Pranita Bahuguni

1. What capabilities or roles should the MID Server have enabled ? : All is default and will be enough

2. Any particular network firewall ports or protocols that should be open? : 443 so it can talk to servicenow instance

3. Minimum hardware/resource requirements for the MID Server in a Service Mapping context? : check docs and use the same. 

4. Required user credentials for deep process and port discovery? : Windows : admin, Linux : Sudo access

5. Should the MID Server be placed in a specific zone or subnet to discover critical application layers and interdependencies? : Mid server needs to communicate with devices, if the commnuication not possible from other zones then yes. 

6. Are there specific logs, configurations, or permissions we should validate ahead of time? : Service account which you will use to run the mid server service : servicenow docs will give you permission details. 

7. Any recommendations on scalability if multiple maps or heavy discovery loads are expected? Plan the discovery schedule so they dont run at the same time. Also, if using class B IP in discovery make sure the MID server has the atleast 10+ GB RAM ( One suggestion go to nowcreate site and look for project workshop deck. It will solve all the above questions without reading multiple pages. 

Do accept the answer.

This is an important step making sure the MID Server is properly configured can save a lot of headaches later. I’d recommend checking the validate.sh script and confirming all the prerequisites for Service Mapping are in place. Let us know how it goes!

Hi @Pranita Bahugun , 

For successful configuration of MID Servers for Service Mapping Project. You need below things. 

1) You first need know, how many service maps you are trying to develop? and decide your approach for Service Mapping -  Top-down, tagged based etc .This will help you understand, how many MID Server you need to configure. 

2) If you have already implemented Discovery in your environment, Its important to separate MID Servers between Discovery and Service Mapping. (Just my approach - Its easy for troubleshooting logs at later point after the implementation and also reduces load on the MID Servers).

3) If you are planning to implement top-down approach, make sure your mid servers are able to discover load balancers in your environment. 

Below are the few helpful ServiceNow documentation links:
