node-ps-data

Get data about process resources without executing terminal commands

• That's right. Unlike existing tools, this module directly retrieves data about processes without needing to open a new shell and wait for a terminal command's response.
• Supports Windows, Linux, and MacOS
• NodeJS module written in C++
• Prebuilt binaries for linux-x64, win32-x64, darwin-x64, and darwin-arm64 (Darwin is the MacOS kernel)

Features

• cpuUserTime(pid): Get user-mode CPU usage for a process in milliseconds.
• cpuKernelTime(pid): Get kernel/system-mode CPU usage for a process in milliseconds.
• cpuTime(pid): Get total CPU usage for a process in milliseconds (equivalent to cpuUserTime(pid) + cpuKernelTime(pid)).
• memInfo(pid): Get current memory usage for a process in bytes.
• memRSS(pid): Get current memory resident/working set size for a process in bytes.
• fileRead(pid): Get total file read size for a process in bytes.
• fileWrite(pid): Get total file write size for a process in bytes.

Installation

npm install node-ps-data

Known Issues and Future Plans

• Build more binaries for other platforms and architectures.
• More library functions:
  • CPU/Memory subcategories (e.g. child process time, pages info, etc.)
  • Network usage
  • GPU memory and usage
  • More!
