InfluxDB
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 withsystemd
. 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'"

Variables ¶
var ( // ErrFieldsRequired is returned when a point does not any fields. ErrFieldsRequired = errors.New("fields required") // ErrFieldTypeConflict is returned when a new field already exists with a different type. ErrFieldTypeConflict = errors.New("field type conflict") // ErrUpgradeEngine will be returned when it's determined that // the server has encountered shards that are not in the `tsm1` // format. ErrUpgradeEngine = errors.New("\n\n" + upgradeMessage + "\n\n") )
Functions ¶
func ErrDatabaseNotFound ¶
ErrDatabaseNotFound indicates that a database operation failed on the specified database because the specified database does not exist.
func ErrRetentionPolicyNotFound ¶ added in v0.9.5
ErrRetentionPolicyNotFound indicates that the named retention policy could not be found in the database.
func IsClientError ¶
IsClientError indicates whether an error is a known client error.
func NewStatistics ¶ added in v0.9.4
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".
