The `datadog-service-map` Sourcegraph extension brings Datadog APM's knowledge of service dependencies to code search workflows, enabling users to visualize and understand the relationships between services in their applications. This extension allows users to see which other services are making calls to a given service, pivot seamlessly to Datadog APM for additional context, and identify potential issues such as increasing errors or latency. It also helps users ensure API calls hit the right endpoints by identifying downstream services and verifying requests are hitting the correct endpoint. By using this extension together with Sourcegraph and Datadog APM, developers can navigate their entire codebase to fix issues quickly and precisely.
