Good to know
GOOD TO KNOW

This training course includes numerous exercises (60% practical) to enhance learning. Even if you are the only one registered, the session will still take place (except in cases of force majeure). A preliminary interview is held between the participant and/or a company representative in order to fully assess the participant’s profile (level, needs, professional context, challenges, etc.).
Assessment : during the training course, the trainer assesses the participants’ progress through multiple-choice questions, role-playing exercises and practical work. Participants receive a certificate of completion at the end of the training course.

This training course is part of our Open Source Training Courses. Discover our other open source trainings to build, administer and secure your Linux and open-source systems.

Objectives of the training: Expert Level Linux Training Course – Diagnose, correct and optimise a system in production
objectives of the Expert Level Linux Training Course

By the end, each participant will be able to :

  • Identify and correct problems related to startup, services, or I/O
  • Diagnose system bottlenecks : memory, CPU, disk, network
  • Optimise the overall performance of a Linux system in production
  • Master advanced logs, profiling and analysis tools
  • Automate monitoring and diagnostic tasks
  • Enhance the stability and resilience of a Linux system
Prerequisites of the training: Expert Level Linux Training Course – Diagnose, correct and optimise a system in production
Prerequisites
  • Have completed the ‘Advanced Linux Administration’ training course or have equivalent experience
  • Be proficient in the basics of administration (users, services, scripts, partitions)
  • Because each participant is unique, a personalised interview with our expert allows us to design a training course that is perfectly aligned with their objectives, level and professional challenges.
Target audience of the training: Expert Level Linux Training Course – Diagnose, correct and optimise a system in production
target audience

Confirmed Linux administrators and system engineers operating in sensitive or high-availability production environments.

FAQ
What does a Linux expert master?

A Linux expert masters fine-grained diagnosis, performance tuning (CPU, memory, I/O, networking), kernel and systemd tuning, debugging with strace/perf/ftrace/eBPF, advanced storage management (LVM, ZFS, RAID), network troubleshooting, and complex Shell/Python scripting.

How do you diagnose a Linux performance issue?

Through a structured method: check CPU (top, pidstat), memory (free, vmstat), I/O (iostat, iotop), network (ss, iftop), then profiling (perf, eBPF with bcc/bpftrace). MFE-IT teaches the USE and RED methods with concrete examples.

What are the key skills to run Linux in production?

Automation (Ansible), IaC (Terraform), monitoring (Prometheus/Grafana), centralized logging (ELK), reliable backups, DRP, patch management, and hardened security. Our MFE-IT training combines these dimensions with troubleshooting.

How long does it take to reach expert-level Linux?

Our Expert-Level Linux training runs over 5 days (35 hours) in a 100% tailor-made format. This volume is necessary to cover advanced cases with real debugging workshops.
