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. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

The check LWRP provides an easy way to add and remove NRPE checks from within cookbooks.

Actions

  • :add creates a NRPE configuration file and restart the NRPE process. Default action.
  • :remove removes the configuration file and restart the NRPE process

Attribute Parameters

  • command_name The name of the check. This is the command that you will call from your nagios_service data bag check
  • warning_condition String that you will pass to the command with the -w flag
  • critical_condition String that you will pass to the command with the -c flag
  • command The actual command to execute (including the path). If this is not specified, this will use #{node['nrpe']['plugin_dir']}/command_name as the path to the command.

nrpe_check "check_load" do
