Learn practical infrastructure monitoring for uptime and resource management using an open monitoring distribution, with Linux and Windows platform experiences, toward installing Nagios on Ubuntu Linux.
Install and set up Nagios on Ubuntu Linux to monitor hosts from a centralized dashboard, track uptime and performance, and generate SLA reports and notifications with SQL database integration.
Learn how Nagios helps monitor the infrastructure of any size, set up notifications for up or down status, and generate SLA reachability reports.
Understand why monitoring is essential: downtime cuts profit, increases troubleshooting costs, and triggers urgency to keep servers fast and reliable while planning upgrades.
Monitor internal and external network usage, including private networks, firewalls, and routers, to determine how much activity occurs and when upgrades are needed.
Use the monitoring tool to reveal that a nighttime backup is still running in the morning, then adjust the scheduled backup so it finishes by morning and reduces user disruption.
Choose Ubuntu server 14.04 LTS for its cleaner, fewer-resource setup and long-term support; explore options for a command-line server or a Windows-like GUI based on preference.
Download the official ISO image file for Nagios on Ubuntu Linux, choosing the 14.0.4 version, noting its CD-sized size and that download time varies with your connection.
Install Ubuntu 14.04 LTS with the fast installer, configure language, networking, hostname, and domain, enable OpenSSH, set disk and bootloader, and prepare a ready Linux server for infrastructure monitoring.

Learn to set up Nagios on Ubuntu Linux for infrastructure monitoring, following simple installation steps, enabling automatic notifications, and monitoring Windows and Linux servers as well as network equipment.
After finishing of this course, you will be Able to Monitor your Network, Servers and all IT Infrastructure using one of the best monitoring tool: Nagios. You will also learn how to fast and easy install the Ubuntu Linux Server and the Open Monitoring Distribution (OMD). I will start with teaching you from scratch (a bare metal machine) with all the necessary steps and software to get everything working. From that point it's only about you to keep an eye on the performance graphs or SLA (Service Level Agreement) Reports and find ways to improve your network in every areas: speed, cost, budget, and so on.
