Seven killer open-source monitoring tools

Seven killer open-source monitoring tools

Do you want to have a clearer understanding of your network? There are no more useful tools than these free tools.

Network and system monitoring is a wide range. There are solutions for monitoring the normal operation of servers, network devices, and applications, as well as solutions for tracking the performance of these systems and devices and providing trend performance analysis. Some tools, like an alarm, can trigger an alarm when a problem is detected, while other tools can even trigger some actions when the alarm is triggered. Some open-source tools are collected to solve some or even most of the problems mentioned above.

Cacti

Cacti is a widely used chart and trend analysis tool that can be used to track and almost draw any monitoring metrics and depict charts. From hard disk utilization to fan speed, Cacti can monitor any metric that can be monitored in a computer management system and quickly convert it into a visual chart.

Nagios

Nagios is a classic-established system and network monitoring tool. It is fast and reliable, and must be customized for applications. Nagios is a challenge for beginners. However, its extremely complex configuration also reflects its power, because it can be applied to almost any monitoring task. The disadvantage is that it is not easy to view, but its powerful functions and reliability make up for this shortcoming.

Icinga

Icinga is a branch of Nagios that is being reconstructed. It provides a comprehensive monitoring and alarm framework and is committed to designing an open and scalable platform like Nagios. However, Nagios and Nagios have different Web interfaces. Icinga 1 is very similar to Nagios, but Icinga 2 is rewritten. Both versions are compatible, and Nagios users can easily transfer to the Icinga 1 platform.

NeDi

NeDi may not be as famous as other tools around the world, but it is indeed a powerful solution for tracking network access. It can smoothly run network infrastructure and device directories to keep track of any events. The current location of any device, including the historical location, can be provided.

NeDi can be used to locate the stolen or lost device as long as the device appears on the network. It can even display all detected nodes on the map. And clearly tell people how the network is connected to the physical device port.
