LTTng: An Open Source Tracing Framework for Linux
This article introduces LTTng (Linux Trace Toolkit: next generation), which is an open source tracing framework for Linux.
Overview
LTTng (Linux Trace Toolkit: next generation) is an open source tracing framework for Linux.
LTTng allows to understand the interactions between multiple components of a given system, i.e.:
- The Linux kernel, using either already available or user-defined instrumentation points
- C/C++ applications
- Java applications
- Python applications
- Any other user space application using the LTTng logger
Tracing all those components with LTTng produces a unified log of events, providing great insight into the system’s behavior.
Also Refer to LTTng Documentation.
