![]() The clinic function starts the diagnostic tools and returns a URL where we can access the diagnostic reports.īy using the node-clinic-diagnostics library, we can easily monitor and optimize the CPU and memory usage of Node processes. Once the terminal window is open, type the command cat /proc/cpuinfo and hit enter. We then call the clinic function with the options object and a callback function. To check the CPU in Linux, the first step is to open a terminal window. The memory object specifies a memory limit of 1GB. The same file is used by free and other utilities to report the amount of free and used memory (both physical and swap) on the system as well as the shared memory and buffers used by the kernel. ![]() The /proc/meminfo file stores statistics about memory usage on the Linux based system. The cpu object specifies a CPU limit of 80% and checks the CPU usage every second. Linux check memory usage using /proc/meminfo file. We then define an options object that specifies the CPU and memory limits for the Node process. It contains real-time information about the system’s memory usage as well as the buffers and shared memory used by the kernel. This is a virtual file that reports the amount of available and used memory. In this code snippet, we first require the clinic module from the node-clinic-diagnostics library. cat Command to Show Linux Memory Information Entering cat /proc/meminfo in your terminal opens the /proc/meminfo file. ![]()
