Geoip2Influx

A python script that will parse the nginx access.log and send geolocation metrics and log metrics to InfluxDB

Usage

Enviroment variables:

These are the default values for all envs. Add the ones that differ on your system.

InfluxDB v1.8.x values

InfluxDB v2.x values

INFLUXDB_V2_TOKEN

If the organization or bucket does not exist, it will try and create them with the token.

[!NOTE] The minimim level of rights needed is write access to the bucket.

InfluxDB

InfluxDB v2.x and v1.8x is supported.

Note: The Grafana dashboard currently only supports InfluxDB v1.8.x

The InfluxDB database/bucket and retention rules will be created automatically with the name you choose.

-e INFLUX_DATABASE=geoip2influx or -e INFLUXDB_V2_BUCKET=geoip2influx

Note

Currently only supports InfluxDB 1.8.x.

Sending Nginx log metrics

Nginx needs to be compiled with the geoip2 module: https://github.com/leev/ngx_http_geoip2_module

1. Add the following to the http block in your nginx.conf file:

geoip2 /config/geoip2db/GeoLite2-City.mmdb {
auto_reload 5m;
$geoip2_data_country_iso_code country iso_code;
$geoip2_data_city_name city names en;
}

log_format custom '$remote_addr - $remote_user [$time_local]'
           '"$request" $status $body_bytes_sent'
           '"$http_referer" $host "$http_user_agent"'
           '"$request_time" "$upstream_connect_time"'
           '"$geoip2_data_city_name" "$geoip2_data_country_iso_code"';

1. Set the access log use the custom log format.

access_log /config/log/nginx/access.log custom;

Multiple log files

If you separate your nginx log files but want this script to parse all of them you can do the following:

As nginx can have multiple access log directives in a block, just add another one in the server block.

Example

	access_log /config/log/nginx/technicalramblings/access.log custom;
	access_log /config/log/nginx/access.log custom;

This will log the same lines to both files.

Then use the /config/log/nginx/access.log file in the NGINX_LOG_PATH variable.

Updates

18.08.24 - Rename env from USE_INFLUX_V2 to USE_INFLUXDB_V2.

10.08.24 - Add support for InfluxDB2.

06.08.24 - Complete refactor of the python code. Deprecate the old geoip2influx.py file.

28.07.24 - Refactor to alpine 3.20. New env required. MAXMINDDB_USER_ID.

21.06.20 - Added $host(domain) to the nginx log metrics. This will break your nginx logs parsing, as you need to update the custom log format.

06.06.20 - Added influx retention policy to try and mitigate max-values-per-tag limit exceeded errors.

• -e INFLUX_RETENTION Default 30d
• -e INFLUX_SHARD Default 2d
• It will only add the retention policy if the database doesn't exist.

30.05.20 - Added logging. Use -e GEOIP2INFLUX_LOG_LEVEL to set the log level.

15.05.20 - Removed GEOIP2_KEY and GEOIP_DB_PATHvariables. With commit https://github.com/linuxserver/docker-letsencrypt/commit/75b9685fdb3ec6edda590300f289b0e75dd9efd0 the letsencrypt container now natively supports downloading and updating(weekly) the GeoLite2-City database!
