Reports are available providing a historical record of events, outages, notifications and alert responses for your review later plus advanced graphs to plan for upgrades before outdated systems catch you offguard. It then sends you alerts via SMS, email, or custom script when critical components fail and recover, so your admins are always notified of important events.
Nagios Core monitors your critical IT infrastructure components from system metrics, servers, applications, services, and network protocols. This is the open-source free version that monitors servers, applications, and services, with features such as a basic user interface with network map, reporting by SMS and email, and basic reports. Two solutions are available for system monitoring: Nagios Core and Nagios XI. As an enduring standard in system and network monitoring, Nagios offers immense benefits such as fast detection of protocol failures and network outages, plus increased availability of services, server, and applications. It is powerful, scalable, reliable, and customizable software, despite being complex to configure. This system monitoring tool for Ubuntu offers complete monitoring of servers and workstations – including service and process state, operating system metrics, and file system usage, plus more. However, you can get sophisticated system monitoring tools that show you more resource utilization information for memory, CPU, disk, and network connections. The most basic tool at your disposal is the System Monitor, a built-in utility for Linux that acts like Windows’ Task Manager and offers basic activity monitoring information from running processes to what consumes the most resources. If you’re using Ubuntu, system monitoring tools will help you spot any service failures or errors before they impact users.
