telegraf

Cookbook to install and configure telegraf

This was influenced by SimpleFinanace/chef-influxdb

Note: Some plugins 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 nil
node['telegraf']['config_file_path'] String Location of the telgraf main config file '/etc/opt/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'] Hash telegraf outputs {'outputs' => ['influxdb' => {'urls' => ['http://localhost:8086'],'database' => 'telegraf','precision' => 's'}]}
node['telegraf']['plugins'] Hash telegraf plugins {'plugins' => {'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 '0.2.4'
  action :create
end

telegraf_config

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

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

telegraf_plugins

Writes out telegraf plugins configuration file.

telegraf_plugins 'default' do
  path node['telegraf']['config_file_path']
  plugins node['telegraf']['plugins']
end

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

For example, to add the nginx plugin:

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

telegraf_plugins 'nginx' do
  path '/etc/opt/telegraf/telegraf.d'
  plugins 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;
