PSLook

Pslook is a NodeJS module retrieving processes informations on GNULinux systems without spawning a new process and in a full non-blocking way using the fs module and the proc filesystem only.

Usage

// List all processes
var ps=require('pslook');
ps.list(function(err, processes) {
    if(err) throw err;
    console.log(processes.length, processes[0].pid);
});
 
// List all node processes
var ps=require('pslook');
ps.list(function(err, process) {
    if(err) throw err;
    console.log(processes.length);
},{'search':/^node .*$/});
 
// List all processes and get their working dir + memory usage
var ps=require('pslook');
ps.list(function(err, process) {
    if(err) throw err;
    console.log(process.cwd);
    console.log(process.statm.size);
},{fields:PSLook.CWD|PSLook.STATM});
 
// Read every available informations for a process by its PID
var ps=require('pslook');
ps.read(aValidPID, function(err, process) {
    if(err) throw err;
    console.log(process.cwd);
    console.log(process.statm.size);
},{fields:ps.ALL});

More OS Support

This library is only intended to run with Unix (particularly Linux) systems. If you wish to have MacOS/Windows support, write your own and mimic the API. I'll be glad to claim its existence there.
