How to use in browser based apps

// this is what you would normally do in client js applications
// setup HTTP based remote logging with logFaces web receiver
var LogManager = require('./LogManager');
var log = LogManager.getLogger("app");

LogManager.setThreshold("INFO");
LogManager.setupRemote({
   application: "my-app-name",
   url: "http://myhost:8050/receivers/myapp"
});
log.warn("this comes from the browser based app");

// turn logging off
LogManager.setThreshold("OFF");

How to use in node.js

// setup UDP remote logging with logFaces UDP receiver
var LogManager = require('./LogManager');
var log = LogManager.getLogger("app");

LogManager.setThreshold("TRACE");
LogManager.setupRemote({
   application: "my-nodejs-app",
   remoteHost: "my-server-host",
   port: "55201"
});
log.info("this comes from node.js server app");

// set MDC context, this will result in all logs sent out to server
// with certain diagnistic context like 'user' and 'job'
LogManager.setContext("user", "foo");
LogManager.setContext("job", "bar");
log.info("this will arive to server with context variables");
