They all look and function pretty similar to the standard “Top” command but each of them focuses on a different part of the system. Iotop – Linux I/O Monitorīy now I’m sure you’ve noticed a pattern with these tools. Mytop hasn’t received any new updates in quite a while but you shouldn’t have any issues running it on most Linux distributions and even some versions of Windows. You can use the tool to monitor threads, performance, databases, queries, and more. Mytop works similar to all the other tools we’ve covered so far but instead of monitoring processes and resources, it focuses on all things related to MySQL. Even more helpful is the fact that Atop also highlights resources that have reached a critical load and indicates the processes that are responsible for it. Similar to Htop, this tool is interactive and gives you detailed information in real-time about the performance of memory, disks, network, and CPUs. This feature is great for keeping track of the performance and resource consumption of various processes over long periods of time. Atop – Advanced System and Process MonitorĪtop is a solid alternative to Atop that also comes with a few extra features, like daily system logging. The only catch here is that Htop requires ncurses in order to run, so you’ll first need to install the programming library if you don’t already have it. Htop is a fully interactive process manager that’s also available as a fully portable application on FreeBSD, MacOS X, and of course various Linux distributions. The tool comes with a cleaner and more intuitive user interface, built-in commands, cross-platform support, and more. Htop is an open-source project that aims to improve upon the regular “Top” command in pretty much every way. The tool also shows you how long each process has been running for as well as some other useful bits of info like buffer size, process PID, and more. You can order the list by things like CPU or memory usage. All you need to do is fire up the command in the Terminal and you’ll immediately be greeted by a list of processes that updates in real-time. The tool is available by default with most Linux distros so there’s no need to install anything in order to access it. Top is the go-to command for many system administrators who need a quick overview of the threads and processes currently running on their system. The tools we’re going to cover in this section are great for monitoring and analyzing processes that directly impact the performance of individual Linux systems (as opposed to networks), though some of them do have other uses as well. Command Line ToolsĮvery Linux user should be at least somewhat familiar with command-line tools and since you’re reading this article, we’ll just go ahead and assume that you already know your away around the Terminal. Without further ado, let’s start things off with one of the most well-known categories. We also went ahead and sorted them by category so feel free to jump ahead to the one you’re most interested in. We know that being a sysadmin is a difficult job that comes with great responsibility and that’s why we put together a comprehensive list of monitoring tools that will make that job a lot easier for you. That might sound a bit intimidating if you’re new to system administration but don’t worry because we’re here to help. If you’re responsible for a sizeable network of systems, on the other hand, you may need a veritable arsenal of tools to make sure that everything is running as smooth as silk. If you’re in charge of only one or two servers you can get away with using just a handful of monitoring tools to keep an eye on things. Some of the most important sysadmin tools are available right off the bat when you first install Linux and can be accessed via the Terminal while others come in the form of open-source software, custom scripts or third-party applications that need to be installed manually. But in order to make the most out of what Linux has to offer, you first need to know where you can find all these tools. A good system administrator can do wonders with the built-in monitoring tools that come with most Linux distributions.
