Still, we'll provide appropriate links to documentation and articles, which will have more information about a particular topic. Note: Since this article will be touching base on most of the monitoring techniques, we will try to be precise in illustrating them. We will be using JVisualVM extensively to demo memory and CPU monitoring. I believe, a Java developer should leverage some of these techniques to fine-tune the code and set the right JVM parameters, while taking the code, all the way from development to production. I will be providing details about the nuances of these tools and when and how they could be used. You also have option to kill the process from the same window by right-clicking on it and selecting the kill option.Īs I mentioned earlier, most of these tools fetch the information from the proc/meminfo file, which can be read directly.This article talks about the basic commands, tools, and techniques to monitor JVM’s Memory and CPU. Similar to Windows Task Manager, you can view the memory usage, CPU usage, and other data for each individual process. In the Processes tab, you can see all the processes that are currently running on your Linux operating system. Resource tab gives the graphical view of the usage. The System Monitor has two tabs we’re interested in: the Processes and Resources tabs. Type “ System Monitor” in the start menu’s search bar and press Enter. You can check the memory, CPU and network usage in real-time in GUI by using System Monitor. You can use -m(mb), -g (gb), -t(total) with free command to understand the value easily –
