Datadog Synthetic private locations play a crucial role in organizations' test infrastructure by providing customizable points of presence for running synthetic tests on internal services. These locations can be deployed using various orchestrators and enable seamless scaling with the rest of the fleet. Datadog now offers full visibility into their health and performance through Private Location Monitoring, which includes out-of-the-box metrics and alerts to monitor private locations and host runtime statistics. This allows teams to ensure that private locations are live, up-to-date, and have enough resources to support running synthetic tests. Additionally, Datadog provides deeper insights into host and container runtime performance when deployed alongside private locations, enabling teams to capture runtime metrics, logs, network activity, and more. With Private Location Monitoring, teams can track the performance of all deployed private locations and set objectives for improving their reliability over time with highly customizable SLOs, ultimately building reliable test infrastructure that enables the deployment of performant applications.
