• node["logstash-forwarder"]["user"] - User for Logstash-forwarder.
• node["logstash-forwarder"]["group"] - Group for Logstash-forwarder.
• node["logstash-forwarder"]["dir"] - Directory to install into.
• node["logstash-forwarder"]["log_dir"] - Log directory.
• node["logstash-forwarder"]["host"] - Host for Logstash-forwarder to connect to.
• node["logstash-forwarder"]["port"] - Port for Logstash-forwarder to connect to.
• node["logstash-forwarder"]["ssl_key"] - SSL key for Logstash-forwarder communication.
• node["logstash-forwarder"]["ssl_certificate"] - SSL certificate for Logstash-forwarder communication.
• node["logstash-forwarder"]["files_to_watch"] - Array of files to watch.
• node["logstash-forwarder"]["logstash_role"] – Role assigned to Logstash server for search.
• node["logstash-forwarder"]["logstash_fqdn"] – FQDN to Logstash server if you're trying to target one that isn't searchable.

• recipe[logstash-forwarder] will install Logstash-forwarder.
• recipe[logstash-forwarder::certificates] will configure a Logstash-forwarder key and certificate.

In order to automatically discover Logstash, setup your roles like the following:

default_attributes(
  "logstash-forwarder" => {
    "logstash_fqdn" => "http://logstash.example.com"
  }
)

Or in a Chef Server environment:

default_attributes()
  "logstash-forwarder" => {
    "logstash_role" => "logstash_server"
  }
)

If you use the logstash-forwarder::certificates recipe, node["logstash-forwarder"]["ssl_certificate_contents"] will be populated with the contents of the Logstash-forwarder certificate to secure client/server communication. The default recipe uses this attribute to create a client-side certificate.
