=== Ingest Geoip Processor Plugin

The GeoIP processor adds information about the geographical location of IP addresses, based on data from the Maxmind databases.
This processor adds this information by default under the `geoip` field. The `geoip` processor can resolve both IPv4 and
IPv6 addresses.

The ingest-geoip plugin ships by default with the GeoLite2 City, GeoLite2 Country and GeoLite2 ASN geoip2 databases from Maxmind made available
under the CCA-ShareAlike 4.0 license. For more details see, http://dev.maxmind.com/geoip/geoip2/geolite2/

The GeoIP processor can run with other geoip2 databases from Maxmind. The files must be copied into the geoip config directory,
and the `database_file` option should be used to specify the filename of the custom database. Custom database files must be stored
uncompressed. The geoip config directory is located at `$ES_HOME/config/ingest-geoip` and holds the shipped databases too.

*Depends on what is available in `database_field`:

* If the GeoLite2 City database is used, then the following fields may be added under the `target_field`: `ip`,
`country_iso_code`, `country_name`, `continent_name`, `region_iso_code`, `region_name`, `city_name`, `timezone`, `latitude`, `longitude`
and `location`. The fields actually added depend on what has been found and which properties were configured in `properties`.
* If the GeoLite2 Country database is used, then the following fields may be added under the `target_field`: `ip`,
`country_iso_code`, `country_name` and `continent_name`. The fields actually added depend on what has been found and which properties
were configured in `properties`.
* If the GeoLite2 ASN database is used, then the following fields may be added under the `target_field`: `ip`,
`asn`, and `organization_name`. The fields actually added depend on what has been found and which properties were configured
in `properties`.

Here is an example that uses the default city database and adds the geographical information to the `geoip` field based on the `ip` field:

[source,js]
--------------------------------------------------
PUT _ingest/pipeline/geoip
{
  "description" : "Add geoip info",
  "processors" : [
    {
      "geoip" : {
        "field" : "ip"
      }
    }
  ]
}
PUT my_index/_doc/my_id?pipeline=geoip
{
  "ip": "8.8.8.8"
}
GET my_index/_doc/my_id
--------------------------------------------------
// CONSOLE

Which returns:

[source,js]
--------------------------------------------------
{
  "found": true,
  "_index": "my_index",
  "_type": "_doc",
  "_id": "my_id",
  "_version": 1,

    "ip": "8.8.8.8",

    }
  }

Here is an example that uses the default country database and adds the
geographical information to the `geo` field based on the `ip` field`. Note that
this database is included in the plugin download. So this:

[source,js]
--------------------------------------------------
PUT _ingest/pipeline/geoip
{
  "description" : "Add geoip info",
  "processors" : [
    {
      "geoip" : {
        "field" : "ip",
        "target_field" : "geo",
        "database_file" : "GeoLite2-Country.mmdb"
      }
    }
  ]
}
PUT my_index/_doc/my_id?pipeline=geoip
{
  "ip": "8.8.8.8"
}
GET my_index/_doc/my_id
--------------------------------------------------
// CONSOLE

returns this:

[source,js]
--------------------------------------------------
{
  "found": true,
  "_index": "my_index",
  "_type": "_doc",
  "_id": "my_id",
  "_version": 1,
  "_source": {
    "ip": "8.8.8.8",
    "geo": {
      "continent_name": "North America",
      "country_iso_code": "US",
    }
  }
}
--------------------------------------------------
// TESTRESPONSE


Not all IP addresses find geo information from the database, When this
occurs, no `target_field` is inserted into the document.

Here is an example of what documents will be indexed as when information for "80.231.5.0"
cannot be found:

[source,js]
--------------------------------------------------
PUT _ingest/pipeline/geoip
{
  "description" : "Add geoip info",
  "processors" : [
    {
      "geoip" : {
        "field" : "ip"
      }
    }
  ]
}

PUT my_index/_doc/my_id?pipeline=geoip
{
  "ip": "80.231.5.0"
}

GET my_index/_doc/my_id
--------------------------------------------------
// CONSOLE

Which returns:

[source,js]
--------------------------------------------------
{
  "_index" : "my_index",
  "_type" : "_doc",
  "_id" : "my_id",
  "_version" : 1,
  "found" : true,
  "_source" : {
    "ip" : "80.231.5.0"
  }
}

[[ingest-geoip-mappings-note]]
===== Recognizing Location as a Geopoint
Although this plugin enriches your document with a `location` field containing
the estimated latitude and longitude of the IP address, this field will not be
indexed as a {ref}/geo-point.html[`geo_point`] type in Elasticsearch without explicitely defining it
as such in the mapping.

You can use the following mapping for the example index above:

[source,js]
--------------------------------------------------
PUT my_ip_locations
{
  "mappings": {
    "_doc": {
      "properties": {
        "geoip": {
          "properties": {
            "location": { "type": "geo_point" }
          }
        }
      }
    }
  }

[[ingest-geoip-settings]]
===== Node Settings

The geoip processor supports the following setting:

`ingest.geoip.cache_size`::

    The maximum number of results that should be cached. Defaults to `1000`.

Note that these settings are node settings and apply to all geoip processors, i.e. there is one cache for all defined geoip processors.
