librato-simple

Simple metrics posting to librato.

Purpose

The existing librato modules do not seem to support tags.

Usage

const config = {
  email: '[email protected]',
  token: 'librato_token',
  debounceTime: 1000,
  limit: 500
};
const librato = require('librato-simple')(config);

librato.queue('some.metric', { color: 'blue', machine: 'thing' });
librato.queue('some.other.metric', { color: 'blue', machine: 'thing' });

// These messages will be queued and sent out after `debounceTime`.
// If you want to force all the messages currently queued to be sent...
librato.send().then(function () {
  // all queued messages should have been sent now.
});

API

Setup

const librato = require('librato-simple')(config);

Options:

• email and token: required auth parameters. Without these being set all calls to .queue() or .send() will do nothing.
• prefix: a prefix to be added to all measurement names.
• debounceTime (default: 1s): how long to wait after the last measurement is queued before all queued measurements are sent.
• limit: the maximum number of measurements to queue before it is sent without any further delay.

Queue measurements to be sent

librato.queue(name, tags, value);

Variables:

• name -- the name of the metric/measurement you are recording.
• tags -- an array of whatever tags to be attached to this measurement.
• value -- the value of this measurement (defaults to 1).

Force all remaining messages to be sent

librato.send().then(function () { /* ... */ });

This flushes the queued measurements and returns a promise that will resolve once all measurements have been sent.

Installation

This module is installed via npm:
