Computer monitoring systems are used to gather data for the purpose of real-time incident notification, performance analysis, and system health verification. Without such a tool, a system administrator would have to login to each machine to collect information on a regular basis. This kind of repetitive task can be automated using a system monitoring tool.
System monitoring can also help identify problems before they escalate to emergency status. This type of software is not only useful for network administrators. Home users with a small network or even just a single computer will benefit from advanced notification provided by system monitoring tools. Knowing that free space on the hard disk is running out, or that a particular server/daemon has gone down can be extremely useful.
These types of systems gather data relating to CPU, memory, network, disk utilization, response time of network services, and much more.
To provide an insight into the quality of software that is available, we have compiled a list of 9 Linux system monitoring tools. Hopefully, there will be something of interest here for anyone who wants to monitor a specific service or situation.
Now, let’s explore the 9 system monitoring applications at hand. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, screenshots, together with links to relevant resources and reviews.
