ktap
ktap is a script-based dynamic tracing tool for Linux. It uses a scripting language and lets users trace the Linux kernel dynamically. ktap is designed to give operational insights with interoperability that allows users to tune, troubleshoot and extend the kernel and applications. It's similar to Systemtap and DTrace. ktap has different design principles from Linux mainstream dynamic tracing languages in that it's based on bytecode, doesn't depend upon GCC, doesn't require compiling kernel module for each script, is safe to use in production environment, and fulfils the embedded ecosystem's tracing needs.
