If everything was configured correctly, Logstash should now be storing the GeoIP coordinates with your Nginx access logs (or whichever application is generating the logs). To put the changes into effect, let’s restart Logstash: Be sure to change this value if you are storing the IP address information in a different field. We are specifying the source as clientip because that is the name of the field that the Nginx user IP address is being stored in. This configures the filter to convert an IP address stored in the clientip field (specified in source).
Under the grok section, add the highlighted portion below:
If your filter is located elsewhere, edit that file instead. In the Adding Filters to Logstash tutorial, the Nginx filter is stored in a file called nf. If you’re using different logs, make the necessary adjustments to the example. We will use Nginx access logs as the example. A fairly ubiquitous application that generates logs with this information is a web server, such as Nginx or Apache. To get Logstash to store GeoIP coordinates, you need to identify an application that generates logs that contain a public IP address that you can filter as a discrete field. Then load the template into Elasticsearch with this command:

On the server that Elasticsearch is installed on, download the Filebeat index template to your home directory: However, we are including this step again in case you skipped it, because the TileMap visualization requires that your GeoIP coordinates are stored in Elasticsearch as a geo_point type. Adding Logstash Filters To Improve Centralized LoggingĪssuming you followed the prerequisite tutorials, you have already done this.
GEO MAXMIND HOW TO
How To Install Elasticsearch, Logstash, and Kibana 4 on Ubuntu 14.04.The first tutorial will set up an ELK stack, and the second one will show you how to gather and filter Nginx or Apache access logs: If you don’t already have these two things, you can follow the first two tutorials in this series.
Additionally, you must have logs that contain IP addresses that can be filtered into a field, like web server access logs. To follow this tutorial, you must have a working ELK stack. Let’s take a look at the prerequisites now.
In Kibana 4, this is known as a Tile Map visualization. Kibana can then read the Geohash strings and draw them as points on a map of the Earth. The coordinate data is stored in Elasticsearch in geo_point fields, and also converted into a geohash string. the approximate physical location of an IP address. Logstash uses a GeoIP database to convert IP addresses into a latitude and longitude coordinate pair, i.e. Here’s a short explanation of how it all works. In this tutorial, we will show you how to create a visual geo-mapping of the IP addresses of your application’s users, by using Elasticsearch, Logstash, and Kibana. This can help you make informed decisions about the ideal geographical location(s) of your application servers and who your current audience is. Traffic analysis by geolocation can provide valuable insight into your user base as it allows you to easily see where they are coming from. Downloading Geo Location Lookup Script (powered by MAXMIND)
