Maxmind is an affordable geo service with broad range of solutions. Furthermore, GeoIP can provide information such as longitude/latitude, connection speed, ISP, company name, domain name, and whether the IP address is an anonymous proxy or satellite provider. The idea behind GeoIP is simple but the process is complex.

Supported Databases This plugin is bundled with City database out of the box. From Maxmind’s description — 'GeoLite2 databases are free IP geolocation databases comparable to, but less accurate than, MaxMind’s GeoIP2 databases'. Please see GeoIP Lite2 license for more details. From Maxmind are also supported in this plugin. If you need to use databases other than the bundled GeoLite2 City, you can download them directly from Maxmind’s website and use the database option to specify their location. The GeoLite2 databases can be downloaded from. If you would like to get Autonomous System Number(ASN) information, you can use the GeoLite2-ASN database.

• Value type is • Default value is 1000 GeoIP lookup is surprisingly expensive. This filter uses an cache to take advantage of the fact that IPs agents are often found adjacent to one another in log files and rarely have a random distribution. The higher you set this the more likely an item is to be in the cache and the faster this filter will run. However, if you set this too high you can use more memory than desired. Since the Geoip API upgraded to v2, there is not any eviction policy so far, if cache is full, no more record can be added. Experiment with different values for this option to find the best performance for your dataset. This MUST be set to a value > 0.

There is really no reason to not want this behavior, the overhead is minimal and the speed gains are large. It is important to note that this config value is global to the geoip_type. That is to say all instances of the geoip filter of the same geoip_type share the same cache. The last declared cache size will win. The reason for this is that there would be no benefit to having multiple caches for different instances at different points in the pipeline, that would just increase the number of cache misses and waste memory.

• Value type is • Default value is 'geoip' Specify the field into which Logstash should store the geoip data. This can be useful, for example, if you have src_ip and dst_ip fields and would like the GeoIP information of both IPs. If you save the data to a target field other than geoip and want to use the geo_point related functions in Elasticsearch, you need to alter the template provided with the Elasticsearch output and configure the output to use the new template.

Even if you don’t use the geo_point mapping, the [target][location] field is still valid GeoJSON.
