Configure and Administrate Nagios Infrastructure Monitoring

Nagios is an open source computer system monitoring, network monitoring and infrastructure monitoring software application. Nagios offers monitoring and alerting services for servers, switches, applications, and services. It alerts the users when things go wrong and alerts them a second time when the problem has been resolved.

Through a series of lectures and hands-on exercises, students will learn how to: design a sensible Nagios infrastructure; install and configure Nagios; locate and deploy Nagios Plugins for both private and public services (on both Windows and Linux); troubleshoot Nagios issues; and integrate Nagios with other monitoring subsystems (such as an SNMP monitoring system)
