Add Host metadata

edit
processors:
  - add_host_metadata:
      cache.ttl: 5m
      geo:
        name: nyc-dc1-rack1
        location: 40.7128, -74.0060
        continent_name: North America
        country_iso_code: US
        region_name: New York
        region_iso_code: NY
        city_name: New York

It has the following settings:

netinfo.enabled
(Optional) Default true. Include IP addresses and MAC addresses as fields host.ip and host.mac
cache.ttl
(Optional) The processor uses an internal cache for the host metadata. This sets the cache expiration time. The default is 5m, negative values disable caching altogether.
geo.name
(Optional) User definable token to be used for identifying a discrete location. Frequently a datacenter, rack, or similar.
geo.location
(Optional) Longitude and latitude in comma separated format.
geo.continent_name
(Optional) Name of the continent.
geo.country_name
(Optional) Name of the country.
geo.region_name
(Optional) Name of the region.
geo.city_name
(Optional) Name of the city.
geo.country_iso_code
(Optional) ISO country code.
geo.region_iso_code
(Optional) ISO region code.
replace_fields
(Optional) Default true. If set to false, original host fields from the event will not be replaced by host fields from add_host_metadata.

The add_host_metadata processor annotates each event with relevant metadata from the host machine. The fields added to the event look like the following:

{
   "host":{
      "architecture":"x86_64",
      "name":"example-host",
      "id":"",
      "os":{
         "family":"darwin",
         "type":"macos",
         "build":"16G1212",
         "platform":"darwin",
         "version":"10.12.6",
         "kernel":"16.7.0",
         "name":"Mac OS X"
      },
      "ip": ["192.168.0.1", "10.0.0.1"],
      "mac": ["00:25:96:12:34:56", "72:00:06:ff:79:f1"],
      "geo": {
          "continent_name": "North America",
          "country_iso_code": "US",
          "region_name": "New York",
          "region_iso_code": "NY",
          "city_name": "New York",
          "name": "nyc-dc1-rack1",
          "location": "40.7128, -74.0060"
        }
   }
}

Note: add_host_metadata processor will overwrite host fields if host.* fields already exist in the event from Beats by default with replace_fields equals to true. Please use add_observer_metadata if the beat is being used to monitor external systems.
