![]() ![]() Process-specific memory information is also available from /proc//statm and /proc//status $ cat /proc/meminfo From the amount of available/free physical memory to the amount of buffer waiting to be or being written back to disk, /proc/meminfo has everything you want to know about system memory usage. ![]() This dynamically updated virtual file is actually the source of information displayed by many other memory related tools such as free, top and ps tools. ![]() The simpliest method to check RAM usage is via /proc/meminfo. Here is a non-exhaustive list of GUI or command-line tools to choose from to check used and free memory on Linux platform. Different tools vary in terms of their monitoring granularity (e.g., system-wide, per-process, per-user), interface (e.g., GUI, command-line, ncurses) or running mode (e.g., interactive, batch mode). Naturally, Linux offers a wealth of options to monitor the usage of the precious memory resource. When it comes to optimizing the performance of a Linux system, physical memory is the single most important factor. What are the available GUI-based or command-line tools for checking current memory usage of Linux? Question: I would like to monitor memory usage on my Linux system. ![]()
