Description of the Expert Level Linux Training Course
In a production environment, system incidents can quickly impact business operations.
This advanced training course teaches you how to quickly identify, diagnose and resolve malfunctions on Linux servers, while implementing sustainable optimisations.
With a focus on practical application, this training course prepares you to deal with critical situations such as slowdowns, crashes, startup errors, CPU/memory saturation, etc. Also discover our Linux/Unix Getting Started Training, our Linux Administration Training Course, our Advanced Linux Administration Training and our Linux Security Training Course.
Format
Remote (recorded sessions).
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 Workstations Training Courses. Discover our other workstation trainings to deploy, administer and secure your fleet of Windows endpoints.
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
- 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
Confirmed Linux administrators and system engineers operating in sensitive or high-availability production environments.

FAQ – Expert-Level Linux Training
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.
