[[geoip-processor]]
=== GeoIP processor
++++
<titleabbrev>GeoIP</titleabbrev>
++++

The `geoip` processor adds information about the geographical location of an
IPv4 or IPv6 address.

[[geoip-automatic-updates]]
By default, the processor uses the GeoLite2 City, GeoLite2 Country, and GeoLite2
ASN IP geolocation databases from http://dev.maxmind.com/geoip/geoip2/geolite2/[MaxMind], shared under the
CC BY-SA 4.0 license. It automatically downloads these databases if your nodes can connect to `storage.googleapis.com` domain and either:

* `ingest.geoip.downloader.eager.download` is set to true
* your cluster has at least one pipeline with a `geoip` processor

{es} automatically downloads updates for these databases from the Elastic GeoIP
endpoint:
https://geoip.elastic.co/v1/database?elastic_geoip_service_tos=agree[https://geoip.elastic.co/v1/database].
To get download statistics for these updates, use the <<geoip-stats-api,GeoIP
stats API>>.

If your cluster can't connect to the Elastic GeoIP endpoint or you want to
manage your own updates, see <<manage-geoip-database-updates>>.

If {es} can't connect to the endpoint for 30 days all updated databases will become
invalid. {es} will stop enriching documents with geoip data and will add `tags: ["_geoip_expired_database"]`
field instead.

  "processors" : [
    {

  ]
}

{
  "ip": "89.160.20.128"
}
GET my-index-000001/_doc/my_id
--------------------------------------------------

Which returns:

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 downloaded automatically. 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-000001/_doc/my_id?pipeline=geoip
{
  "ip": "89.160.20.128"
}
GET my-index-000001/_doc/my_id
--------------------------------------------------

returns this:

[source,console-result]
--------------------------------------------------
{
  "found": true,
  "_index": "my-index-000001",
  "_id": "my_id",
  "_version": 1,
  "_seq_no": 65,
  "_primary_term": 1,
  "_source": {
    "ip": "89.160.20.128",
    "geo": {
      "continent_name": "Europe",
      "country_name": "Sweden",
      "country_iso_code": "SE"
    }

}
--------------------------------------------------
// 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-000001/_doc/my_id?pipeline=geoip
{
  "ip": "80.231.5.0"
}

GET my-index-000001/_doc/my_id
--------------------------------------------------

Which returns:

[source,console-result]
--------------------------------------------------
{
  "_index" : "my-index-000001",
  "_id" : "my_id",
  "_version" : 1,
  "_seq_no" : 71,

[[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": {

[[manage-geoip-database-updates]]
==== Manage your own IP geolocation database updates

If you can't <<geoip-automatic-updates,automatically update>> your IP geolocation databases
from the Elastic endpoint, you have a few other options:

* <<use-proxy-geoip-endpoint,Use a proxy endpoint>>
* <<use-custom-geoip-endpoint,Use a custom endpoint>>
* <<manually-update-geoip-databases,Manually update your IP geolocation databases>>

[[use-proxy-geoip-endpoint]]
**Use a proxy endpoint**

If you can't connect directly to the Elastic GeoIP endpoint, consider setting up
a secure proxy. You can then specify the proxy endpoint URL in the
<<ingest-geoip-downloader-endpoint,`ingest.geoip.downloader.endpoint`>> setting
of each node’s `elasticsearch.yml` file.

In a strict setup the following domains may need to be added to the allowed
domains list:

* `geoip.elastic.co`
* `storage.googleapis.com`

[[use-custom-geoip-endpoint]]
**Use a custom endpoint**

You can create a service that mimics the Elastic GeoIP endpoint. You can then
get automatic updates from this service.

. Download your `.mmdb` database files from the
http://dev.maxmind.com/geoip/geoip2/geolite2[MaxMind site].

. Copy your database files to a single directory.

. From your {es} directory, run:
+
[source,sh]
----
./bin/elasticsearch-geoip -s my/source/dir [-t target/directory]
----

. Serve the static database files from your directory. For example, you can use
Docker to serve the files from an nginx server:
+
[source,sh]
----
docker run -v my/source/dir:/usr/share/nginx/html:ro nginx
----

. Specify the service's endpoint URL in the
<<ingest-geoip-downloader-endpoint,`ingest.geoip.downloader.endpoint`>> setting
of each node’s `elasticsearch.yml` file.
+
By default, {es} checks the endpoint for updates every three days. To use
another polling interval, use the <<cluster-update-settings,cluster update
settings API>> to set
<<ingest-geoip-downloader-poll-interval,`ingest.geoip.downloader.poll.interval`>>.

[[manually-update-geoip-databases]]
**Manually update your IP geolocation databases**

. Use the <<cluster-update-settings,cluster update settings API>> to set
`ingest.geoip.downloader.enabled` to `false`. This disables automatic updates
that may overwrite your database changes. This also deletes all downloaded
databases.

. Download your `.mmdb` database files from the
http://dev.maxmind.com/geoip/geoip2/geolite2[MaxMind site].
+
You can also use custom city, country, and ASN `.mmdb` files. These files must
be uncompressed. The type (city, country, or ASN) will be pulled from the file
metadata, so the filename does not matter.

. On {ess} deployments upload database using
a {cloud}/ec-custom-bundles.html[custom bundle].

. On self-managed deployments copy the database files to `$ES_CONFIG/ingest-geoip`.

. In your `geoip` processors, configure the `database_file` parameter to use a
custom database file.

[[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.

[[geoip-cluster-settings]]
===== Cluster settings

[[ingest-geoip-downloader-enabled]]
`ingest.geoip.downloader.enabled`::
(<<dynamic-cluster-setting,Dynamic>>, Boolean)
If `true`, {es} automatically downloads and manages updates for IP geolocation databases
from the `ingest.geoip.downloader.endpoint`. If `false`, {es} does not download
updates and deletes all downloaded databases. Defaults to `true`.

[[ingest-geoip-downloader-eager-download]]
`ingest.geoip.downloader.eager.download`::
(<<dynamic-cluster-setting,Dynamic>>, Boolean)
If `true`, {es} downloads IP geolocation databases immediately, regardless of whether a
pipeline exists with a geoip processor. If `false`, {es} only begins downloading
the databases if a pipeline with a geoip processor exists or is added. Defaults
to `false`.

[[ingest-geoip-downloader-endpoint]]
`ingest.geoip.downloader.endpoint`::
(<<static-cluster-setting,Static>>, string)
Endpoint URL used to download updates for IP geolocation databases. For example, `https://myDomain.com/overview.json`.
Defaults to `https://geoip.elastic.co/v1/database`. {es} stores downloaded database files in
each node's <<es-tmpdir,temporary directory>> at `$ES_TMPDIR/geoip-databases/<node_id>`.
Note that {es} will make a GET request to `${ingest.geoip.downloader.endpoint}?elastic_geoip_service_tos=agree`,
expecting the list of metadata about databases typically found in `overview.json`.

The GeoIP downloader uses the JDK's builtin cacerts. If you're using a custom endpoint, add the custom https endpoint cacert(s) to the JDK's truststore.

[[ingest-geoip-downloader-poll-interval]]
`ingest.geoip.downloader.poll.interval`::
(<<dynamic-cluster-setting,Dynamic>>, <<time-units,time value>>)
How often {es} checks for IP geolocation database updates at the
`ingest.geoip.downloader.endpoint`. Must be greater than `1d` (one day). Defaults
to `3d` (three days).
