[[geoip-processor]]
=== GeoIP Processor

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` module 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 `ingest-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 `ingest-geoip` config directory is located at `$ES_CONFIG/ingest-geoip`.

*Depends on what is available in `database_file`:

* 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,console]
--------------------------------------------------
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
--------------------------------------------------

Which returns:

[source,console-result]
--------------------------------------------------
{
  "found": true,
  "_index": "my_index",
  "_id": "my_id",
  "_version": 1,
  "_seq_no": 55,
  "_primary_term": 1,
  "_source": {
    "ip": "8.8.8.8",
    "geoip": {
      "continent_name": "North America",
      "country_iso_code": "US",
      "location": { "lat": 37.751, "lon": -97.822 }
    }
  }
}
--------------------------------------------------
// TESTRESPONSE[s/"_seq_no": \d+/"_seq_no" : $body._seq_no/ s/"_primary_term":1/"_primary_term" : $body._primary_term/]

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 module. So this:

[source,console]
--------------------------------------------------
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
--------------------------------------------------

returns this:

[source,console-result]
--------------------------------------------------
{
  "found": true,
  "_index": "my_index",
  "_id": "my_id",
  "_version": 1,
  "_seq_no": 65,
  "_primary_term": 1,
  "_source": {
    "ip": "8.8.8.8",
    "geo": {
      "continent_name": "North America",
      "country_iso_code": "US",
    }
  }
}
--------------------------------------------------
// TESTRESPONSE[s/"_seq_no": \d+/"_seq_no" : $body._seq_no/ s/"_primary_term" : 1/"_primary_term" : $body._primary_term/]


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,console]
--------------------------------------------------
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
--------------------------------------------------

Which returns:

[source,console-result]
--------------------------------------------------
{
  "_index" : "my_index",
  "_id" : "my_id",
  "_version" : 1,
  "_seq_no" : 71,
  "_primary_term": 1,
  "found" : true,
  "_source" : {
    "ip" : "80.231.5.0"
  }
}
--------------------------------------------------
// TESTRESPONSE[s/"_seq_no" : \d+/"_seq_no" : $body._seq_no/ s/"_primary_term" : 1/"_primary_term" : $body._primary_term/]

[[ingest-geoip-mappings-note]]
===== Recognizing Location as a Geopoint
Although this processor 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 explicitly defining it
as such in the mapping.

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

[source,console]
--------------------------------------------------
PUT my_ip_locations
{
  "mappings": {
    "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.
