An Open-Source Time Series Database

InfluxDB is an open source 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.
  • 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.

Installation

We recommend installing InfluxDB using one of the pre-built packages. Then start InfluxDB using:

  • 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.

Getting Started

Create 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'"
