This code will help to populate the Manufacturer if that empty on CMDB_CI table
This script is used in ServiceNow to automatically fill in the missing manufacturer information for Configuration Items (CIs) in the CMDB (Configuration Management Database).
1. Predefined Mapping:
The script starts with a list of known model names and their corresponding manufacturer names.For example, a model called ThinkPad T14 is made by Lenovo, and MacBook Pro 16 is made by Apple
2. Look Up Manufacturer:
* It defines a function that looks up the manufacturer’s record in the core_company table (based on the name) and gets its unique ID (sys_id).
3. Find CIs Missing a Manufacturer:
* The script goes through all CIs in the cmdb_ci table where the manufacturer field is empty.
4. Update Missing Manufacturer:
* For each of those CIs:
* It checks the model name.
* If the model is in the predefined mapping:
* It looks up the correct manufacturer in the core_company table.
* It updates the CI record by setting the manufacturer field with the correct sys_id.
* It also logs that the update was successful.
* If the manufacturer is not found in the system, it logs a warning.
5. Final Log:
* After going through all matching CIs, it logs how many records were successfully updated.
Processes a list of IPs, finds matching CIs in cmdb_ci_computer, checks their discovery history, retrieves the related Discovery Status number, and logs the results as JSON. Logs a message if no CI or history is found.
This script is a ServiceNow troubleshooting utility designed to help administrators quickly check if specific IP addresses were successfully discovered by the Discovery process.
