The Linux Trace Toolkit

Analyzing performance is one of the most important tasks of a system administrator; here's how to do it using Linux.
LTT's Future

As this article has shown, LTT is an effective tool for recording critical system information. Moreover, it is rather simple to use and the information presented is accessible to a large portion of the community. In an academic environment, LTT can be used in a course on operating systems, helping students get first hand experience with a live operating system and how it interacts with different applications.

Given its capabilities, modularity, extensibility and minimal overhead, we hope to see the tracing code become part of the mainstream Linux kernel soon (maybe not in 2.3/2.4 currently in feature freeze, but in the next development branch). Another possible application for LTT, which gathered a lot of interest, is to use it as part of a security auditing system with Tripwire-type capabilities. At the time of this writing, the authors know of at least one Linux distribution which plans to include LTT as part of their standard distribution.

Karim Yaghmour (karym@opersys.com) is an operating system freak. He's been playing around with OS internals for quite a while and has even written his own OS. He's currently completing his master's degree at the Ecole Polytechnique de Montréal, where the Linux Trace Toolkit is part of his research. He started his own consulting company, Opersys, Inc., that specializes in operating systems (http://www.opersys.com/) and offers expertise and courses on Linux internals and real-time derivatives.

Michel Dagenais (michel.dagenais@polymtl.ca) is a professor at Ecole Polytechnique de Montréal. He has authored or co-authored a large number of scientific publications in the fields of software engineering, structured documents on the Web and object-oriented distributed programming for collaborative applications.

Ciao
I've started working on LTT and I've found useful this page.
I wonder if the Author could update the Figures 3 and 4 (maybe wrong!).

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
