CLTRACE is a new DTrace-inspired observability framework for Common Lisp applications that enables programmable debugging of live production systems with minimal interference. The alpha-quality tool allows developers to deploy debugging programs and create probes interactively on-the-fly, providing aggregation capabilities across function calls. This brings powerful dynamic tracing capabilities typically found in systems like DTrace to the Common Lisp ecosystem.
Background
DTrace is a comprehensive dynamic tracing framework originally created for Solaris that allows developers to troubleshoot system and application problems in production environments. Common Lisp has historically lacked sophisticated production debugging tools comparable to those available in other language ecosystems.
