GeoIP2 Filter

Look up Geo data from IP

GeoIP2 Filter allows you to enrich the incoming data stream using location data from GeoIP2 database.

Configuration Parameters

This plugin supports the following configuration parameters:

Getting Started

The following configuration will process incoming remote_addr, and append country information retrieved from GeoLite2 database.

    Name   dummy
    Dummy  {"remote_addr": ""}

    Name geoip2
    Match *
    Database GeoLite2-City.mmdb
    Lookup_key remote_addr
    Record country remote_addr %{country.names.en}
    Record isocode remote_addr %{country.iso_code}

    Name   stdout
    Match  *

Each Record parameter above specifies the following triplet:

  1. The field name to be added to records (country)

  2. The lookup key to process (remote_addr)

  3. The query for GeoIP2 database (%{country.names.en})

By running Calyptia Fluent Bit with the configuration above, you will see the following output:

{"remote_addr": "", "country": "United States", "isocode": "US"}

Note that the GeoLite2-City.mmdb database is available from MaxMind's official site.
