Identifying country, operating system type, and browser type from the log file


This section explains how we can calculate the user country name, operation system type, and browser type by analyzing the Apache log line. By identifying the country name, we can easily identify the location where our site is getting more attention and the location where we are getting less attention. Let's perform the following steps to calculate the country name, operating system, and browser from the Apache log file:

  1. We are using the open source geoip library to calculate the country name from the IP address. Add the following dependencies in the pom.xml file:
       <dependency> 
             <groupId>org.geomind</groupId> 
             <artifactId>geoip</artifactId> 
             <version>1.2.8</version> 
       </dependency> 
  1. Add the following repository into the pom.xml file:
        <repository> 
             <id>geoip</id> 
             &lt...
