telegraf

Cookbook to install and configure telegraf

This was influenced by SimpleFinanace/chef-influxdb

Note: Some inputs will require other packages be installed and that is out of scope for this
cookbook. ie. [netstat] requires lsof

Tested Platforms

  • CentOS 7.1
  • Ubuntu 14.04

Requirements

  • Chef 12.5+

Usage

This cookbook can be used by including telegraf::default in your run list and settings attributes

as needed. Alternatively, you can use the custom resources directly.

Attributes

Key Type Description Default
node['telegraf']['version'] String Version of telegraf to install, nil = latest '0.10.0-1'
node['telegraf']['config_file_path'] String Location of the telgraf main config file '/etc/telegraf/telegraf.conf'
node['telegraf']['config'] Hash Config variables to be written to the telegraf config {'tags' => {},'agent' => {'interval' => '10s','round_interval' => true,'flush_interval' => '10s','flush_jitter' => '5s'}
node['telegraf']['outputs'] Array telegraf outputs ['influxdb' => {'urls' => ['http://localhost:8086'],'database' => 'telegraf','precision' => 's'}]
node['telegraf']['include_repository'] [TrueClass, FalseClass] Whether or not to pull in the InfluxDB repository to install from. true
node['telegraf']['inputs'] Hash telegraf inputs {'cpu' => {'percpu' => true,'totalcpu' => true,'drop' => ['cpu_time'],},'disk' => {},'io' => {},'mem' => {},'net' => {},'swap' => {},'system' => {}}

Custom Resources

telegraf_install

Installs telegraf and configures the service. Optionally specifies a version, otherwise the latest available is installed

telegraf_install 'default' do
  install_version '0.10.0-1'
  action :create
end

telegraf_config

Writes out the telegraf configuration file. Optionally includes outputs and inputs.

telegraf_config 'default' do
  path node['telegraf']['config_file_path']
  config node['telegraf']['config']
  outputs node['telegraf']['outputs']
  inputs node['telegraf']['inputs']
end

telegraf_outputs

Writes out telegraf outputs configuration file. You can call this several times to create multiple outputs config files.

telegraf_outputs 'default' do
  outputs node['telegraf']['outputs']
end

telegraf_inputs

Writes out telegraf inputs configuration file.

telegraf_inputs 'default' do
  inputs node['telegraf']['inputs']
end

You can call this several times to create multiple inputs config files. You'll need to specify different names for each telegraf_inputs resource, so they'll create separate config files.

For example, to add the nginx input:

node.default['telegraf']['nginx'] = {
  'nginx' => {
    'urls' => ['http://localhost/status']
  }
}

telegraf_inputs 'nginx' do
  inputs node['telegraf']['nginx']
  service_name 'default'
  reload true
end

Note that there are two optional parameters for this resource that could've been left out in this case:
- service_name [default: 'default'] if you need to override which service should be restarted when the config changes;
- reload [default: true] whether to restart the service when the config changes;
