## What it is
A Linux port of Sun's DTrace dynamic tracing framework, delivered as a dynamically loadable kernel module plus userland tools. It brings DTrace-style observability to Linux without modifying kernel source code.

## Use cases
- trace kernel and userland activity on linux with dtrace
- debug performance problems with dtrace probes
- load dtrace as a kernel module without patching the kernel
- port solaris dtrace scripts to linux
- instrument system calls and functions for diagnostics

## When to choose
- you specifically need DTrace semantics and D-script compatibility on Linux
- you cannot modify or rebuild your kernel but can load modules
- you are studying how DTrace was ported to Linux

## When to avoid
- you want actively maintained tracing - prefer eBPF/bpftrace or SystemTap
- you need a project with a clear license and ongoing support
- you run modern kernels where this port may no longer build

## Facets
