Usage

This cookbook implements resources to install NetData and manage its
configuration files.

Recipies

Installs NetData using the netdata_install resource with default parameters.

install_netdata

Deprecated, please use default recipe or netdata_install resource.

Resources

netdata_install

Installs NetData from source on supported platforms.

netdata_install 'default' do
  git_repository 'https://github.com/firehol/netdata.git'
  git_revision 'master'
  git_source_directory '/tmp/netdata'
  autoupdate true
end

• git_repository - Location of git repository to pull the NetData source.
• git_revision - Tag/Branch/Commit to checkout.
• git_source_directory - Location to sync the repository to on the server.
• install_path - Change the location where NetData is installed.
• autoupdate - Allow NetData to autoupdate itself via a cron entry.

It's highly recommended to use a different path than /tmp/netdata for git_source_directory and in future versions the default path will change. This is encouraged because when autoupdate is set to true NetData will create a symbolic link from the source directory to cron.d and you don't want NetData to create a symbolic link to anything in /tmp

netdata_config

Manages the main netdata.conf file. Call this as many times as needed.
Each name should be unique. (i.e. web, global)

netdata_config 'web' do
  owner 'netdata'
  group 'netdata'
  base_directory '/etc'
  configurations(
    'bind to' => 'localhost'
  )
end

Resulting file content (/etc/netdata/netdata.conf):

[web]
  bind to = localhost

• owner - User to own the file
• group - Group to own the file
• base_directory - Parent folder that holds the NetData configuration files.
• configurations - Hash of key, value pairs for customizing NetData.

This resource will restart the NetData service automatically.

netdata_python_plugin

Manages python plugin configuration files.

netdata_python_plugin 'mysql' do
  owner 'netdata'
  group 'netdata'
  base_directory '/etc'
  global_configuration(
    'retries' => 5
  )
  jobs(
    'tcp' => {
      'name' => 'local',
      'host' => 'localhost',
      'port' => 3306   
    }
  )
end

Resulting file content (/etc/netdata/python.d/mysql.conf):

# GLOBAL
retries: 5

# JOBS
tcp:
  name: local
  host: localhost
  port: 3306

• owner - User to own the file
• group - Group to own the file
• base_directory - Parent folder that holds the NetData configuration files.
• global_configuration - Hash of global variables for the plugin.
• jobs - Hash of jobs that tell NetData to pull statistics from.

This resource will restart the NetData service automatically.

netdata_bind_rndc_conf
