$ npm install influx

Version 4.x.x is compatible with InfluxDB 0.9.x

Version 3.x.x is compatible with InfluxDB 0.8.x - 3.x will no longer have updates by core contributers, please consider upgrading.

Create a client instance (database not required for all methods):

var influx = require('influx')
var client = influx({
  //cluster configuration 
  hosts : [
      host : 'localhost',
      port : 8060, //optional. default 8086 
      protocol : 'http' //optional. default 'http' 
  // or single-host configuration 
  host : 'localhost',
  port : 8086, // optional, default 8086 
  protocol : 'http', // optional, default 'http' 
  username : 'dbuser',
  password : 'f4ncyp4ass',
  database : 'my_database'

A list of all configuration values can be found below.

You can either pass a single hostname or an array of hostnames. Node-influx uses round-robin balancing to distribute the requests across all configured hosts. When a host is unreachable, node-influx tries to resubmit the request to another host and disables the failed host for 60 seconds (timeout value is configurable). If all servers fail to respond, node-influx raises an error.

You can also pass an URL or an array of URLs:

var influx = require('influx')
var client = influx('http://dbuser:f4ncyp4ass@localhost:8060/my_database')
// or 
client = influx({
  hosts: ['', ''],
  username: 'dbuser',
  password: 'f4ncyp4ass',
  database: 'my_database'
Option Description
username username
password password
database database name
host hostname, e.g. 'localhost'
port [optional] influxdb port, default: 8086
protocol [optional] protocol, default: http
hosts [optional] Array of hosts for cluster configuration, e.g. [ {host: 'localhost', port : 8086},...] Port is optional
depreciatedLogging [optional] logging function for depreciated warnings, defaults to console.log
failoverTimeout [optional] number of ms node-influx will take a host out of the balancing after a request failed, default: 60000
requestTimeout [optional] number of ms to wait before a request times out. defaults to 'null' (waits until connection is closed). Use with caution!
maxRetries [options] max number of retries until a request raises an error (e.g. 'no hosts available'), default : 2
timePrecision [optional] Time precision, default : ms

Sets the default timeout for a request. When a request times out the host is removed from the list of available hosts and the request is resubmitted to the next configured host. The default value is null (will wait forever for a respose).

Be careful with this setting. If the value is too low, slow queries might disable all configured hosts.

client.setRequestTimeout( value )

Sets the failover timeout for a host. After a host has been removed from balancing, it will be re-enabled after 60 seconds (default). You can configure the timeout value using this function.

client.setFailoverTimeout( value )

Returns an array of available hosts.

getHostsAvailable( ) 

Returns an array of disabled hosts. This can be useful to check whether a host is unresponsive or not.

client.getHostsDisabled( )

Writes a point to a series - requires database user privileges

var point = { attr : value, time : new Date()};
client.writePoint(seriesName, values, tags, [options,] function(errresponse) { })

values can be either an objekt or a single value. For the latter the columname is set to value. You can set the time by passing an object propety called time. The time an be either an integer value or a Date object. When providing a single value, don't forget to adjust the time precision accordingly. The default value is ms. The parameter options is optional and can be used to set the time precision.

//write a single point with two values and two tags. time is omitted 
client.writePoint(, {value: 232, value2: 123}, { foo: 'bar', foobar: 'baz'}, done)
//write a single point with the value "1". The value "1" corresponds to { value : 1 } 
client.writePoint(, 1, { foo: 'bar', foobar: 'baz'}, done)
//write a single point, providing an integer timestamp and time precision 's' for seconds 
client.writePoint(, {time: 1234567890, value: 232}, null, {precision : 's'}, done)
//write a single point, providing a Date object. Precision is set to default 'ms' for milliseconds. 
client.writePoint(, {time: new Date(), value: 232}, null,  done)

Writes multiple points to a series - requires database user privileges

Points is an array of points. Each point containing two objects - the actual values and tags.

var points = [
  //first value with tag 
  [{value: 232}, { tag: 'foobar'}],
  //second value with different tag 
  [{value: 212}, { someothertag: 'baz'}],
  //third value, passed as integer. Different tag 
  [123, { foobar: 'baz'}],
  //value providing timestamp, without tags 
  [{value: 122, time : new Date()}]
client.writePoints(seriesName, points, [options,] callback) { }

Writes multiple point to multiple series - requires database user privileges

var points = [
  //first value with tag 
  [{value: 232}, { tag: 'foobar'}],
  //second value with different tag 
  [{value: 212}, { someothertag: 'baz'}],
  //third value, passed as integer. Different tag 
  [123, { foobar: 'baz'}],
  //value providing timestamp, without tags 
  [{value: 122, time : new Date()}]
var points2 = [
  //first value with tag 
  [{value: 1232}, { tag: 'foobar'}],
  //second value with different tag 
  [{value: 223212}, { someothertag: 'baz'}],
  //third value, passed as integer. Different tag 
  [12345, { foobar: 'baz'}],
  //value providing timestamp, without tags 
  [{value: 23122, time : new Date()}]
var series = {
    series_name_one : points,
    series_name_two : points2
client.writeSeries(series, [options,] function(err,response) { })

Please note that there's a POST limit at about 2MB per request. Do not submit too many points at once.

Queries the database and returns an array of parsed responses. - requires database user privileges.

var query = 'SELECT MEDIAN(column) FROM myseries WHERE time > now() - 24h';
client.query([database,] query, function(errresults) { })

If database is omitted, node-influx uses the database defined in the default options. Since InfluxDB 0.9, all values with different tags are stored in different timeseries. The response from InfluxDB contains an array of values for each series that matches the request. To make things easier the query function now returns a parsed response, meaning that all points from all series are merged into a single array of points and their tags. You can still retrieve the raw response from InfluxDB using client.queryRaw().

You can also pass multiple queries at once. The callback returns an array of series, one series per query.

client.query('SELECT * FROM myseries; SELECT AVG(VALUE) as avgvalue from myseries', function (errresults) {});
// -> results =[  
//   [ { value : 1, tagname : 'tagvalue'}, {value : 3, othertag : 'value}], 
//   [ {avgvalue : 2.345}] 
// ] 

Same as function query but returns the raw response from InfluxDB.

var query = 'SELECT MEDIAN(column) FROM myseries WHERE time > now() - 24h';
client.queryRaw([database,] query, function(errresults) { })

Creates a continuous query - requires admin privileges

client.createContinuousQuery('testQuery', 'SELECT COUNT(value) INTO valuesCount_1h FROM ' + + ' GROUP BY time(1h) ', function (errres) {} )

Fetches all continuous queries from a database - requires database admin privileges

getContinuousQueries( function(err,arrayContinuousQueries) { })

Drops a continuous query from a database - requires database admin privileges

dropContinuousQuery( queryName, [databaseName,] callback) { }

Fetches all retention policies from a database.

client.getRetentionPolicies(databaseName, function(err,response) {} )

Creates a new retention policy - requires admin privileges.

client.createRetentionPolicy(rpName, databaseName, duration, replication, isDefault, function(err,response) {} )
client.createRetentionPolicy('my_ret_pol_name', 'my_database', '1d', 1, true, function (err,resonse) {})

Alters an existing retention policy - requires admin privileges.

client.alterRetentionPolicy(rpName, databaseName, duration, replication, isDefault, function(err,response) {} )

As Jeff Atwood puts it... Read the source, Luke. If you're still stuck, read the ./examples/* files and the ./test.js file.

Either install InfluxDB or use a docker container to run the service:

docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 tutum/influxdb

Then to run the test harness use npm test.
