Linux Trace Toolkit (LTT) is a tracing tool that permits to get all the possible execution information from the Linux Kernel. It is based on kernel instrumentation and a high-speed relay file system to copy the information from the kernel space to the user space.
Linux Trace Toolkit Viewer (LTTV) is the second generation of visualization tool. It is based on a trace format (the files where the data is recorded on disk) written by the LTTng tracer.
This document explains all the steps that are necessary in order to record a trace with LTT and view it with LTTV.
