Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

Description

This cookbook provides providers and resources to configure and manage Diamond Diamond is a python daemon that collects system metrics and publishes them to Graphite. It is capable of collecting cpu, memory, network, i/o, load and disk metrics. Additionally, it features an API for implementing custom collectors for gathering metrics from almost any source.

Requirements

Requires Chef 0.7.10 or higher for Lightweight Resource and Provider support. Chef 0.8+ is recommended. While this cookbook can be used in chef-solo mode, to gain the most flexibility, we recommend using chef-client with a Chef Server.

Recipes

The example recipe installs Diamond in the most basic of configurations

Installation Prefix problems

  • diamond_collectors_path and diamond_installation_path exist in the configure resource because on how you install distutils Diamond will install its collectors in /usr/local/share/diamond/collectors instead of /usr/share/diamond/collectors. If your OS/Distribution installs the collectors in /usr/share/diamond/collectors you should set this accordingly.

Feel free to submit pull requests that can improve this problem.

plugin.rb

Enable / Disable plugins with this resource.

Actions:

  • name - String - name of plugin to enable / disable

Generic Usage

The following example will just configure Diamond with the GraphiteHandler and with the default collectors enabled only.

diamond_install "#{node['hostname']}" do  
  action :git  
end  
diamond_configure "#{node['hostname']}" do   
  action :config  
  diamond_handlers [ "diamond.handler.graphite.GraphiteHandler" ]    
  graphite_handler({"host" => "127.0.0.1","port" => 2003, "timeout" => 15})  
end  

Basic Usage with Plugins

The following example will configure Diamond with the archive.ArchiveHandler and graphite.GraphiteHandler with the PingCollector and CPUCollector enabled.

diamond_install "#{node['hostname']}" do  
  action :git  
end  
diamond_configure "#{node['hostname']}" do  
  action :config  
  diamond_handlers [ "diamond.handler.archive.ArchiveHandler", "diamond.handler.graphite.GraphiteHandler" ]  
  graphite_handler({"host" => "127.0.0.1","port" => 2003, "timeout" => 15})  
end  
diamond_plugin "CPUCollector" do  
  action :enable  
  options({})  
end  
diamond_plugin "PingCollector" do  
  action :enable  
  options({  
    "enabled" => "True",  
    "bin" => "/bin/ping",  
    "use_sudo" => "False",  
    "sudo_cmd" => "/usr/bin/sudo",  
    "target_1" => "google.com",  
    "target_2" => "aol.com"  
  })  
end  

Advanced Usage with Custom Collectors Installed

diamond_install "#{node['hostname']}" do  
  action :git  
end  
diamond_configure "#{node['hostname']}" do  
  action :config  
  diamond_handlers [ "diamond.handler.archive.ArchiveHandler", "diamond.handler.graphite.GraphiteHandler" ]  
  graphite_handler({"host" => "127.0.0.1","port" => 2003, "timeout" => 15})  
end  
directory "/usr/local/share/diamond/collectors/latency_http" do  
  action :create  
end  
cookbook_file "/usr/local/share/diamond/collectors/latency_http/latency_http.py" do  
  source "latency_http.py"
  cookbook "our_custom"
end
diamond_plugin "LatencyHTTTPCollector" do  
  action :enable  
  options({  
    "enabled" => "True",  
    "target_1" => "host1.com",  
    "target_2" => "host2.com"  
  })  
end
