Datadog Synthetic Monitoring allows developers to proactively test their applications for availability and performance issues before they impact end-users. The platform supports API tests, including simulated HTTP requests, SSL certificate validation, DNS resolution checks, TCP connection testing, and endpoint pings. Recently, Datadog has added support for UDP and WebSocket API tests to ensure the low-latency requirements of real-time applications such as customer support chat platforms and video streaming services are met. These new tests utilize the UDP transport layer protocol and the WebSocket application layer protocol to facilitate fast data transmission and bidirectional client-server communication. With these tests, developers can detect server connectivity issues, verify network timings, and identify potential problems with their latency-critical applications before they impact end-users. The platform also allows users to configure tests to run on demand or periodically from globally distributed managed locations, as well as private locations within their internal networks.
