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. The free command is one of the widely used commands to quickly check for RAM stats because it’s available on most Linux distributions. It’s used to print the physical and swap memory usage by default, it prints to standard output. We then call the clinic function with the options object and a callback function. free is the simplest of all the commands we’ll see.

The memory object specifies a memory limit of 1GB. The cpu object specifies a CPU limit of 80% and checks the CPU usage every second. 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.
