Create Critical P1 Incident from Alert using GlideJsonPath - Pull5 (#2561)

* script.js

Automatically create a problem record from incident volume
Use case: Automatically create a problem record if a specific Configuration Item (CI) is associated with more than a certain number of incidents within a defined timeframe. 
Code snippet
This code can be placed in a Scheduled Script Execution or an After Insert Business Rule to check new incidents

* README.md

* Script.js

Identify the oldest active incident for each assignment group. This helps managers focus on long-running tickets that may require special attention.

* script.js

This example searches a JSON document for all developers listed under the specified path.

* Update README.md

* script.js

Identify inactive users who still have unresolved incidents. This helps with offboarding processes and ensures incidents aren't left unattended.

+Create Critical P1 Incident from Alert This script provides the server-side logic for a Scripted REST API endpoint in ServiceNow. 
+It allows external monitoring tools to send alert data via a POST request, which is then used to automatically create a high-priority, P1 incident. 
+Overview The API endpoint performs the following actions: Receives a JSON Payload: Accepts a POST request containing a JSON payload with alert details (severity, description, source, CI). Parses Data: Uses the GlideJsonPath API to efficiently extract the necessary alert information from the JSON body. Validates Request: Ensures that the severity is CRITICAL and the description is present. It sends an appropriate error response for invalid or incomplete data. Creates Incident: If the data is valid, it creates a new incident record in the incident table. Sets Incident Fields: Automatically populates the incident's short_description, description, source, and sets the impact, urgency, and priority to 1 - High/Critical. Associates CI: If a ci_sys_id is provided in the payload, it links the incident to the correct Configuration Item. Logs Activity: Logs the successful creation of the incident in the system log for tracking and auditing purposes. Responds to Sender: Sends a JSON response back to the external system, confirming success or failure and providing the new incident's number and sys_id. Expected JSON payload The external system should send a POST request with a JSON body structured like this: json { "alert": { "severity": "CRITICAL", "description": "The primary database server is down. Users are unable to log in.", "source": "Dynatrace", "configuration_item": "DB_Server_01", "ci_sys_id": "a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6" } } Use code with caution.
+
+Installation As a Scripted REST API Resource Create the Scripted REST API: Navigate to System Web Services > Scripted REST APIs. 
+Click New and fill in the details: Name: CriticalAlertIncident API ID: critical_alert_incident Save the record.
+
+Create the Resource: On the Resources related list of the API record, click New. 
+Name: PostCriticalIncident HTTP Method: POST Relative Path: / Copy and paste the provided script into the Script field. Configure Security: Ensure appropriate authentication is configured for the API, such as OAuth or Basic Auth, to secure the endpoint. Customization Change Priority/Impact: Modify the grIncident.setValue() lines to set different priority or impact levels based on the payload (e.g., if (severity == 'MAJOR') { grIncident.setValue('priority', 2); }). Add Additional Fields: Extend the script to parse and set other incident fields, such as assignment_group, caller_id, or category, based on data from the incoming payload. Enrich Incident Data: Perform a lookup on the CI to fetch additional information and add it to the incident description or other fields. Handle Different Severity Levels: Add if/else logic to handle different severity values (e.g., MAJOR, MINOR) from the source system, creating incidents with different priorities accordingly.
+
+Dependencies This script requires the GlideJsonPath API, which is available in Jakarta and later releases. 
+The API endpoint must be secured with appropriate authentication to prevent unauthorized access.
+
+Considerations
+
+Security: This API endpoint is a powerful integration point. 
+Ensure that it is properly secured and that only trusted sources are allowed to create incidents. Error Handling: The script includes robust error handling for common failures (missing data, insertion failure) but should be extended to handle specific use cases as needed. Testing: Thoroughly test the endpoint with a variety of payloads, including valid data, missing data, and invalid data, to ensure it behaves as expected.
