Our Advanced Analytics features allow you to create incident reports by service directly in the UI. If you do not have advanced reporting on your account, there is a script - get_incidents.py - that can be used to generate an incident report for a specific service.
In order to use this script for a single service, you need to set the
service_id values on lines 9, 11, and 13 to a REST API v1 key, your PagerDuty subdomain's API endpoint URL (i.e.
https://your-company.pagerduty.com/api/v1), and a service's ID. You can obtain your service's ID by logging into your PagerDuty account, then going to Configuration > Services, clicking on a service and looking at the URL. The service ID is the 7-character string at the end of the URL.
