OpsGenie's integration with Datadog enables the automatic syncing of alerts between both platforms, allowing OpsGenie customers to leverage Datadog's alert notification and incident response capabilities. This integration also facilitates the creation of new alerts in OpsGenie from within the Datadog UI, as well as the posting of OpsGenie alerts into Datadog for further discussion and analysis. The integration supports various communication channels and collaboration tools, including Slack, HipChat, and chatOps capabilities, allowing responders to assess situations, resolve issues quickly, and take preventive steps. By consolidating related alerts into one incident, teams can save time and ensure that no alert is lost, while also correlating metrics and alerts for easy monitoring of entire IT infrastructure.
