Datadog introduces Single Step Instrumentation, a new APM configuration mechanism that activates distributed tracing across all critical services with just one command. This eliminates the need for frontend code changes or manually adding the APM SDK to individual applications, ensuring seamless and immediate observability. Single Step Instrumentation is now generally available for services running on Linux operating systems and Docker containers hosted on Linux. It simplifies the process of enabling distributed tracing, whether you’re installing the Datadog Agent on a new host for the first time or adding tracing to a host that already has the Agent running.
