Don't let this gap widen
Without Nagios mastery, 80% of outages remain undetected for more than 4 hours, resulting in downtimes costing companies an average of 5 000 € per hour.
IT teams lose 35% of their time on firefighting instead of innovating, with 62% of incidents tied to faulty monitoring according to Gartner.
In 2026, companies without proactive supervision see their competitiveness drop against reactive competitors.
Every day without Nagios skills exposes your infrastructure to unnecessary risks and hinders growth.
Immersive discovery of Nagios's key concepts, complete installation of a Nagios server on Ubuntu with Apache and initial configuration, exploration of the CGI web interface to visualize statuses in real-time, first monitoring tests on local hosts and basic services like HTTP/SSH, practical exercises to create your first functional supervision environment, with resolution of common errors and log validation.
In-depth exploration of Nagios object configuration via definition files, creation of reusable templates to supervise a fleet of remote hosts, definition of critical services such as MySQL databases or application processes, use of Nagios commands for custom checks, practical workshops on real enterprise cases with host grouping by department, generation of your first consolidated view and optimization of polling times.
Mastery of Nagios plugins to extend supervision to advanced metrics, installation and configuration of NRPE for remote monitoring without SNMP, development of custom checks via Bash/Python scripts, setup of alert escalations and notifications via email/Slack, incident simulations on your ongoing infrastructure project with measured response times, creation of silencing rules to avoid false positives in production.
Integration of Nagios with visualization tools like NagVis for interactive dashboards, generation of periodic reports on availability and SLAs, optimization of Nagios performance via tuning of intervals and data retention, cluster deployment for high availability, final project on a complete enterprise scenario with configuration export and maintenance plan, delivery of ready-to-use deliverables for your IT system.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
