Telegraf

Minimal gem to send metrics to a local telegraf agent.

This gem only uses the line protocol from the influxdb gem and does not depend on a specific version. This may break in the future but does not restrict you in using a your preferred influxdb version.

Installation

gem 'telegraf'

And then execute:

$ bundle

Or install it yourself as:

$ gem install telegraf

Usage

Configure telegraf socket listener e.g.:

[[inputs.socket_listener]]
  service_address = "udp://localhost:8094"


telegraf = Telegraf::Agent.new 'udp://localhost:8094'
telegraf = Telegraf::Agent.new # default: 'udp://localhost:8094'

telegraf.write('demo',
    tags: {tag_a: 'A', tag_b: 'B'},
    values: {value_a: 1, value_b: 1.5})

telegraf.write([{
    series: 'demo',
    tags: {tag_a: 'A', tag_b: 'B'},
    values: {value_a: 1, value_b: 1.5}
}])

There is not buffer or batch handling, nor connection pooling or keep alive. Each #write creates a new connection (unless it's a datagram connection).

There is no exception handling.
