statsd-parser

a streaming parser for the statsd protocol

installation

node.js

  1. install npm
  2. npm install statsd-parser
  3. var statsd_parser = require('statsd-parser');

usage

basics

var statsd_parser = require("statsd-parser")
  , parser = statsd_parser.parser()
  ;

parser.onerror = function (e) {
  // an error happened. e is the error
};

parser.onstat = function (txt, obj) {
  // got some value
};
parser.onend = function () {
  // parser stream is done, and ready to have more stuff written to it.
};

parser.write('foo.bar:1|c').close();

//
// stream usage
// takes the same options as the parser
//
var stream = require("statsd-parser").createStream(options);

stream.on("error", function (e) {
  // unhandled errors will throw, since this is a proper node
  // event emitter.
  console.error("error!", e);
  // clear the error
  this._parser.error = null;
  this._parser.resume();
})

stream.on("stat", function (txt, obj) {
  // same object as above
});
//
// pipe is supported, and it's readable/writable
// same chunks coming in also go out
//
fs.createReadStream("file.statsd")
  .pipe(stream)
  .pipe(fs.createReadStream("file-fixed.statsd"))
