As far as I know there isn’t a module (yet) to do this cross-platform. You can use the child process API to launch tools that will give the data you want. For Windows, just launch the built-in tasklist process.
var exec = require('child_process').exec;
exec('tasklist', function(err, stdout, stderr) {
// stdout is a string containing the output of the command.
// parse it and look for the apache and mysql processes.
});
