GitHub Apps is a service that automates key processes in workflows and enables direct interaction with the GitHub API. Integrating Datadog with GitHub allows users to add valuable context to notebooks, access links to Git repositories, and view inline code snippets for stack traces. This integration helps reduce mean time to resolution (MTTR) by enabling faster troubleshooting and pinpointing the root cause of issues without leaving Datadog. Additionally, Datadog's GitHub integration works seamlessly with Notebooks, allowing users to create richer postmortems, investigations, and reports by adding link previews of issues and pull requests. The combination of GitHub and source code integrations in Datadog provides a powerful tool for faster troubleshooting and efficient access to relevant information.
