node.js - Getting id of worker from inside worker process -

-

using node.js cluster module, straightforward id of worker process.

https://nodejs.org/api/cluster.html

that be:

cluster.on('fork', function (worker) {     console.log('a worker', worker.id, 'was forked.'); });

but how can id of worker inside worker itself? how come cluster module doesn't give worker id when cluster forks worker?

do have send worker it's cluster id master process?

i looking akin to:

process.id (as opposed process.pid)

or 

process.worker.id

in case, having trouble figuring out id of worker inside worker itself.

var cluster = require('cluster');  if (cluster.ismaster) {   console.log('i master');   cluster.fork();   cluster.fork(); } else if (cluster.isworker) {   console.log('i worker #' + cluster.worker.id); }

as in here
