MongoDB Atlas provides pre-built and customizable alerts for various channels, including Slack and Hipchat, to help customers monitor their databases. Due to popular demand, Datadog has been added as an optional endpoint for these alerts, allowing companies using Datadog to quickly view database alerts from a dashboard they regularly use. Setup is simple, requiring only the pasting of a Datadog API key and selecting the "Datadog" endpoint for new or existing alerts. With this integration, users can easily monitor their MongoDB Atlas databases alongside other application monitoring tools like Datadog.
