The advantage of using htop instead of top is that the former has a color-coded UI, which makes parsing the information easier. Htop uses virtually the same syntax: htop -p RES – displays the resident memory for the process, i.e., RAM usage in gigabytes.VIRT – displays the total amount of memory used by the process, including memory for shared libraries.Top will start monitoring the process and display its memory footprint. Next, we use top with the PID as a parameter to print memory usage: top -p Since a Minecraft server uses 25565, the lsof command will output the server’s PID. This command will find a running process that opened a specified local internet port, in this case 25565. We can do this in the following way: lsof -i:25565 -t We also need a way to find the PID (process identifier) number for our Minecraft server process. Top comes preinstalled on most Linux distributions, while htop can be installed with your package manager of choice (aptitude on Debian-based distributions, including Ubuntu). To do this, we need a command line utility such as top or htop for monitoring system processes. We can also explicitly check how much RAM our Minecraft server is using while it’s running. The following command will launch Minecraft server with 2GB of RAM: java -Xmx2048M -Xms2048M -jar server.jar nogui Check Using the top or htop Commands Whenever we launch our server, we can adjust these numbers to give it a different amount of RAM. In the example above, we dedicated approximately 1GB of RAM to the server. The command line options – Xmx and – Xms specify the maximum and minimum amount of RAM dedicated to the server. Let’s examine the command for starting a Minecraft server on Linux: java -Xmx1024M -Xms1024M -jar server.jar nogui We can use command line parameters when launching a Minecraft server to keep RAM usage within certain boundaries. Specify Memory Use When Launching the Server

Linux users can check Minecraft server RAM usage in several ways. Check Minecraft Server RAM on a Linux Server

There are various methods for checking how much RAM a Minecraft: Java Edition server is using. To avoid this, you should carefully monitor your Minecraft server’s RAM usage. If your Minecraft server uses up all available RAM, players will start experiencing lag and other network issues. Minecraft: Java Edition servers consume a lot of PC resources, especially RAM.
