InfluxDB Circle CI

An Open-Source, Distributed, Time Series Database

InfluxDB v0.9.0 is now out. Going forward, the 0.9.x series of releases will not make breaking API changes or breaking changes to the underlying data storage. However, 0.9.0 clustering should be considered an alpha release.

InfluxDB is an open source distributed time series database with no external dependencies. It's useful for recording metrics, events, and performing analytics.

Features

  • Built-in HTTP API so you don't have to write any server side code to get up and running.
  • Data can be tagged, allowing very flexible querying.
  • SQL-like query language.
  • Clustering is supported out of the box, so that you can scale horizontally to handle your data.
  • Simple to install and manage, and fast to get data in and out.
  • It aims to answer queries in real-time. That means every data point is indexed as it comes in and is immediately available in queries that should return in < 100ms.

Getting Started

The following directions apply only to the 0.9.0 release or building from the source on master.

Building

You don't need to build the project to use it - you can use any of our pre-built packages to install InfluxDB. That's the recommended way to get it running. However, if you want to contribute to the core of InfluxDB, you'll need to build. For those adventurous enough, you can follow along on our docs.

Starting InfluxDB
  • service influxdb start if you have installed InfluxDB using an official Debian or RPM package.
  • systemctl start influxdb if you have installed InfluxDB using an official Debian or RPM package, and are running a distro with systemd. For example, Ubuntu 15 or later.
  • $GOPATH/bin/influxd if you have built InfluxDB from source.
Creating your first database
curl -G 'http://localhost:8086/query' --data-urlencode "q=CREATE DATABASE mydb"
Insert some data
curl -XPOST 'http://localhost:8086/write?db=mydb' \
-d 'cpu,host=server01,region=uswest load=42 1434055562000000000'

curl -XPOST 'http://localhost:8086/write?db=mydb' \
-d 'cpu,host=server02,region=uswest load=78 1434055562000000000'

curl -XPOST 'http://localhost:8086/write?db=mydb' \
-d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'
Query for the data
curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT * FROM cpu WHERE host='server01' AND time < now() - 1d"
Analyze the data
curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"

var (
	// ErrFieldsRequired is returned when a point does not any fields.

Functions

func ErrDatabaseNotFound 

func ErrDatabaseNotFound(name string) error

ErrDatabaseNotFound indicates that a database operation failed on the specified database because the specified database does not exist.

func ErrRetentionPolicyNotFound 

func ErrRetentionPolicyNotFound(name string) error

ErrRetentionPolicyNotFound indicates that the named retention policy could not be found in the database.

func IsClientError 

func IsClientError(err error) bool

IsClientError indicates whether an error is a known client error.

func NewStatistics 

func NewStatistics(key, name string, tags map[string]string) *expvar.Map

NewStatistics returns an expvar-based map with the given key. Within that map is another map. Within there "name" is the Measurement name, "tags" are the tags, and values are placed at the key "values".
