node-dtrace-provider
Adds native DTrace probes to Node.js applications for custom runtime instrumentation.
What is node-dtrace-provider?
dtrace-provider is a Node.js native extension that allows developers to create custom DTrace providers and probes for their applications. It enables runtime instrumentation to expose application-specific metrics and events to DTrace, separate from the Node.js runtime's built-in probes. This helps in debugging, performance monitoring, and gaining deep insights into application behavior.
Node.js developers and system administrators working on platforms with DTrace support (e.g., Mac OS X, Solaris, FreeBSD) who need advanced application-level tracing and observability.
Developers choose dtrace-provider because it provides a seamless way to integrate custom DTrace probes into Node.js apps without requiring root access or build-time changes. Its efficient callback-based firing minimizes overhead for disabled probes, and cross-platform stub support ensures compatibility across environments.
