DTrace, short for "dynamic tracing", is a powerful diagnostic tool and tracing framework. It is invaluable for performance monitoring, tuning, and for getting insights into almost any aspect of a running system. In this paper we investigate how we can leverage the DTrace operating system-level instrumentation framework [9] to conduct runtime verification. To this end, we develop graphviz2dtrace, a tool for producing monitor scripts in DTrace's domain-specific scripting language D for specification formulas written in LTL3, a three-valued variety of the well-known Linear Temporal Logic. We evaluate the tool by analyzing a small stack-implementation and a multi-process system.
