atsd-api v0.0.6

ATSD Node.js API client

The ATSD API Client for Node.js enables developers to easily interact with the Axibase Time Series Database through its Data and Meta API.

Installation

This client can be installed using npm:

$ sudo npm install atsd-api

Usage

ATSD Client

The base class is ATSDClient, an instance which can be created using ATSDClient(options) where options is an object:

The purpose of ATSDClient is to make general requests to ATSD. It has an asynchronous method request, as well as separate methods for each type of request:

ATSDClient.request(method, path, params, payload, callback)

ATSDClient.getRequest(path, params, payload, callback)
ATSDClient.postRequest(path, params, payload, callback)
ATSDClient.putRequest(path, params, payload, callback)
ATSDClient.patchRequest(path, params, payload, callback)
ATSDClient.deleteRequest(path, params, payload, callback)

The arguments are as follows:

API Methods

Entities, Metrics, Properties, Alerts, and Series are all subclasses of ATSDClient and use the same constructor. They hold the implementations of ATSD API methods:

Data API

Meta API

There is also a number of convenience functions dedicated to making some requests easier to execute. Unlike the functions listed above, they don't replicate the signatures of ATSD API methods.

For statistics and units used to aggregate the data through series queries, there exist corresponding "enumerations" in class Series: Series.statistic and Series.unit.

Setup

var atsd_api = require('atsd-api');

var options = {
  url: '...',
  user: '...',
  password: '...'
};

var entities   = new atsd_api.Entities(options);
var metrics    = new atsd_api.Metrics(options);
var series     = new atsd_api.Series(options);
var properties = new atsd_api.Properties(options);
var alerts     = new atsd_api.Alerts(options);

Examples

Series

// inserting series data without versions
series.insertData('temperature', 'sensor001', {}, [
    {'d': '2015-11-23T08:19:00.000Z', 'v': 51},
    {'d': '2015-11-23T08:20:00.000Z', 'v': 52}
  ], function(error_insert, response, _) {
    if (!error_insert) {
      console.log('Insert: ' + response.statusCode);
    }
  }
);

> Insert: 200

// inserting series data with versions
series.insertData('temperature', 'sensor001', {}, [
    {'d': '2015-11-23T08:21:00.000Z', 'v': 50, 'version': {'status': 'provisional', 'source': 'gateway-1'}}
  ], function(error_insert, response, _) {
    if (!error_insert) {
      console.log('Insert with versions: ' + response.statusCode);
    }
  }
);

> Insert with versions: 200
