Usage

To install Zabbix agent just include zabbix_lwrp default recipe into your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[zabbix_lwrp]"
  ]
}

This recipe should be included before all usage of LWRP, because connection to zabbix server is established here.

To install Zabbix server include the following recipes:

{
  "name":"my_node",
  "run_list": [
    "recipe[zabbix_lwrp::default]",
    "recipe[zabbix_lwrp::database]",
    "recipe[zabbix_lwrp::server]",
    "recipe[zabbix_lwrp::web]"
  ]
}

For examples of LWRP see fixture cookbook in tests/fixtures/cookbooks.
