Collectd Build Status

DESCRIPTION

Configure and install the collectd monitoring daemon.

REQUIREMENTS

This cookbook has only been tested on Ubuntu 10.04 and 12.04.

The following cookbooks are required:

ATTRIBUTES

  • collectd.basedir - Base folder for collectd output data.
  • collectd.plugin_dir - Base folder to find plugins.
  • collectd.types_db - Path to the files to read graph type information from.
  • collectd.interval - Time period in seconds to wait between data reads.

USAGE

Three main recipes are provided:

  • collectd::client or collectd::default - Install a unconfigured collectd
  • collectd::client_collectd - Install collectd and configure it to send data to a collectd server.
  • collectd::client_graphite - Install collectd and configure it to send data to a carbon server.
  • collectd::server - Install collectd and configure it to recieve data from clients.

The client recipe will use the search index to automatically locate the server hosts, so no manual configuration is required.

LWRPs

A lwrp is included for configuring plugins.

collectd_plugin

You may use the collectd_plugin provider to configure and enable collectd plugins.

%w(disk entropy memory swap).each do |plug|
  collectd_plugin plug
end

collectd_plugin 'syslog' do
  options :log_level => 'info',
    :notify_level => 'warning'
end

collectd_plugin 'tcpconns' do
  options :listening_ports => true
end

collectd_plugin 'myplugin' do
  type 'exec'
  options :exec => ['user', '/path/to/exec.sh']
end

# Taken from http://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_filecount
collectd_plugin 'qmail' do
  type 'filecount'
  options 'Directory' => {
    '/var/qmail/queue/mess' => {
      :instance => 'qmail-message'
    },
    '/var/qmail/queue/todo' => {
      :instance => 'qmail-todo'
    }
  }
end

# Taken from https://collectd.org/wiki/index.php/Plugin:Tail#Invalid_SSH_login_attempts
collectd_plugin 'sshd' do
  type 'tail'
  options :file => {
    '/var/log/auth.log' => {
      :instance => 'auth',
      :match => [
        {
          :regex => "\\<sshd[^:]*: Invalid user [^ ]+ from\\>",
          :d_s_type => 'CounterInc',
          :type => 'counter',
          :instance => 'sshd-invalid_user'
        }
      ]
    }
  }
end

The options hash is converted to collectd-style settings automatically. Any symbol key will be converted to camel-case. In the above example :listening_ports will be output as the key ListeningPorts. If the key is already a string, this conversion is skipped. If the value is an array, it will be output as a separate line for each element.

purge_plugins

To purge unused plugins create a ruby block after all your other plugin declarations. This will only remove plugins that that were originally declared using the collectd_plugin lwrp.

ruby_block 'collectd_purge_plugins' do
  block { collectd_purge_plugins() }
end

collectd_authfile

You may use the collectd_authfile provider to create a collectd authfile by adding and removing users.

collectd_authfile 'gregf' do
  password  supersecure
end

collectd_authfile 'baduser' do
  action :remove
end
