syslog-ng Open Source Edition 3.16 - Release Notes

Looking up GeoIP2 data from IP addresses

The syslog-ng OSE application can lookup IP addresses from an offline GeoIP2 database, and make the retrieved data available in name-value pairs. Depending on the database used, you can access country code, longitude, and latitude information and so on.

The syslog-ng OSE application works with the Country and the City version of the GeoIP2 database, both free and the commercial editions. The syslog-ng OSE application works with the mmdb (GeoIP2) format of these databases. Other formats, like csv are not supported.

 NOTE:

To access longitude and latitude information, download the City version of the GeoIP2 database.

There are two types of GeoIP2 databases available.

  • GeoLite2 City:

    • free of charge

    • less accurate

  • GeoIP2 City:

    • has to be purchased

    • more accurate

Unzip the downloaded database (for example, to the /usr/share/GeoIP2/GeoIP2City.mmdb file). This path will be used later in the configuration.
