Timescale Cloud integrates with Datadog to enable users to monitor their TimescaleDB databases in production. To set up this integration, users need an active Datadog account and a service running on Timescale Cloud. They must create an exporter in Timescale Cloud that exposes metrics for the specific service they want to monitor, which is then sent to Datadog using OpenTelemetry. Users can configure alerts on their service metrics in Datadog, allowing them to stay informed about resource usage such as memory, CPU, and storage. This integration provides users with a convenient way to run their database fleet while leveraging the power of TimescaleDB for time-series data and PostgreSQL for relational data, all without requiring a credit card.
