LTTng Reference Traces

This repository contains a set of LTTng and CTF traces that can be used by various projects for testing.

The traces can be synthetic or real-world traces and represent various conditions. Unless specified otherwise, these traces are complete (no lost packets or discarded events).

A description of each trace should be given in this README.

The traces are all compressed with the tar.xz format (tar xvJf to extract), the archives contain a directory of the same name (without the suffix) that contains all the trace files/folders

List of traces

• picotrace: a tiny trace (20 events) generated with CTFWriter that looks like a kernel trace (except the cpu_id field is part of the event context).
• 16-cores-rt: a real kernel trace of 2 seconds recorded with LTTng 2.9.0-pre on a 16 cores server running the PREEMPT_RT kernel 4.1.10-rt10). No particular activity, 388738 events, 14MB.
• basic-kernel-analysis: a real kernel trace of ~5 seconds recorded with LTTng 2.10 on a 2 core virtual machine with all the events necessary to run lttnganalyses. The script to generate a similar trace is also provided.
