Datadog has integrated its services with HipChat, allowing users to share graphs, events, and alerts directly in their chat rooms. To set up the integration, users need to create a notification-only API Auth Token called "Datadog" in HipChat, navigate to Datadog's Integrations page, install the integration, and add the names of the chat rooms where they want to receive updates. Once active, users can mention @hipchat-room_name from the Datadog event stream to share updates without needing to copy or paste. The integration also allows users to automatically keep their team up-to-date on pressing issues by sending alerts directly to HipChat and sharing graphs in real-time.
