IBM explicitly identifiesTrace Web SDKas the framework component for implementing HTTP tracing within Instana’s observability ecosystem. The latest content in the IBM Instana documentation (v1.0.307, aligning to v1.0.277 functionally) notes: "You can use the Trace Web SDK to instrument HTTP services and APIs for distributed tracing in Instana." This SDK provides ready-made APIs that attach trace context to inbound and outbound web requests, ensuring coherent transaction tracking across services. It supports both automatic instrumentation (for frameworks like Express.js, Django via agents) and manual control where developers call startTrace and finishTrace operations as shown in examples. Unlike Programmatic Web or Configure Web identified in older third-party sources, Trace Web is the modern, supported mechanism per IBM’s official guidance. Haskell is unsupported as an SDK target. Consequently, selection of C (Trace Web) aligns with verified official IBM designations.

Instana’s Synthetic Monitoring module allows administrators to script user journeys and API checks to validate service performance and uptime. According to official IBM documentation, "Synthetic monitoring API scripts use JavaScript as the scripting language for configuring user flows and custom API tests." Instana has designed its synthetic user interface to interpret JavaScript natively which provides powerful, flexible constructs for simulating user interactions, custom API payloads, test logic, and error handling. This ensures broad compatibility with real browser environments and highly customizable synthetic scenarios. Java, Python, and Go are not supported for browser-based or synthetic API scripting in Instana’s synthetic monitors. JavaScript is chosen for its ubiquity and ease of integration with DOM-like and API interaction patterns, supporting the most common web-based automation needs as described in the documentation.
