Simple Log Service:Convert IP addresses

Last Updated:Feb 01, 2024

If you use Logtail to collect logs, you can use the processor_geoip plug-in to convert IP addresses in logs to geographical locations. A geographical location includes the following information: country, province, city, longitude, and latitude. This topic describes the parameters of the processor_geoip plug-in. This topic also provides examples on how to configure the plug-in.

Important
  • Form configuration: You can use form configuration to collect text logs and container stdout and stderr.

  • Editor configuration in JSON: You cannot use editor configuration in JSON to collect text logs.

Entry point

If you want to use a Logtail plug-in to process logs, you can add a Logtail plug-in configuration when you create or modify a Logtail configuration. For more information, see Overview.

Usage notes

Note
  • GeoIP databases are not included in the Logtail installation package. You must download and configure a GeoIP database on the server on which Logtail is installed. We recommend that you download a database that can provide the city information of an IP address. For more information, see GeoLite2 Free Geolocation Data.

  • Make sure that the database file is in the MMDB format.

Form configuration

  • Parameters

    Set Processor Type to Convert IP Addresses. Then, configure other parameters based on the following table.
