You can set the maximum log level on a logger at runtime. By default, a logger writes to STDOUT, but given a writeable file path, it will log directly to a file. Instantiation: // node/common.js style var logger = require('./logger').createLogger(); // logs to STDOUT var logger = require('./logger').createLogger('development.log'); // logs to a file 2)  simple-node-logger A simple multi-level logger for console, file, and rolling file appenders. Features include: levels: trace, debug, info, warn, error and fatal levels (plus all and off) flexible ap...

It runs the code in a separate thread, and can communicate the results back to the main thread. Cluster workers are separate instances of your Node process, which are primarily used for load balancing incoming requests across multiple processes, to take advantage of multi-core processors.
