Ruby client library for InfluxDB.
$ [sudo] gem install influxdb
Or add it to your Gemfile, etc.
Connecting to a single host:
require 'influxdb'
influxdb = InfluxDB::Client.new host: "influxdb.domain.com"Connecting to multiple hosts (with built-in load balancing and failover):
require 'influxdb'
influxdb = InfluxDB::Client.new hosts: ["influxdb1.domain.com", "influxdb2.domain.com"]Create a database:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.create_database(database)Create a user for a database:
require 'influxdb'
influxdb = InfluxDB::Client.new
database = 'site_development'
new_username = 'foo'
new_password = 'bar'
influxdb.create_database_user(database, new_username, new_password)Update a database user:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.update_database_user(database, username, :password => "new_password")Write some data:
require 'influxdb'
username = 'foo'
password = 'bar'
database = 'site_development'
name = 'foobar'
influxdb = InfluxDB::Client.new database, :username => username, :password => password
# Enumerator that emits a sine wave
Value = (0..360).to_a.map {|i| Math.send(:sin, i / 10.0) * 10 }.each
loop do
data = {
:value => Value.next
}
influxdb.write_point(name, data)
sleep 1
endWrite data with time precision:
Time precision can be set in 2 ways, either in the client initialization
require 'influxdb'
username = 'foo'
password = 'bar'
database = 'site_development'
name = 'foobar'
time_precision = 's'
influxdb = InfluxDB::Client.new database, :username => username,
:password => password,
:time_precision => time_precision
data = {
:value => 0,
:time => Time.now.to_i
}
influxdb.write_point(name, data)or in the write call
require 'influxdb'
username = 'foo'
password = 'bar'
database = 'site_development'
name = 'foobar'
time_precision = 's'
influxdb = InfluxDB::Client.new database, :username => username, :password => password
data = {
:value => 0,
:time => Time.now.to_i
}
influxdb.write_point(name, data, false, time_precision)List cluster admins:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.get_cluster_admin_listList databases:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.get_database_listList database users:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.get_database_user_list(database)List a database user:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.get_database_user_info(database, username)Delete a database:
require 'influxdb'
influxdb = InfluxDB::Client.new
database = 'site_development'
influxdb.delete_database(database)Delete a database user:
require 'influxdb'
influxdb = InfluxDB::Client.new
influxdb.delete_database_user(database, username)Querying:
require 'influxdb'
username = 'foo'
password = 'bar'
database = 'site_development'
influxdb = InfluxDB::Client.new database, :username => username, :password => password
influxdb.query 'select * from time_series_1' do |name, points|
puts "#{name} => #{points}"
