Description
The presentation will describe the usage of Systemtap, in CERN Scientific Linux environment. Systemtap is a tool that allows developers and administrators to write and reuse simple scripts to deeply examine the activities of a live Linux system. We will go through the life cycle of a system tap module : creation, packaging, deployment. It will focus on how we used it recently at CERN as a workaround to patch a 0-day.

Before CERN he worked at the former astrophysics department of CERN, now called the European Southern Observatory, based in Chile. He was used to maintain the core
