Introduction

In this tutorial we learn how to install syslog-ng-mod-add-contextual-data on Kali Linux.

What is syslog-ng-mod-add-contextual-data

syslog-ng-mod-add-contextual-data is:

syslog-ng is an enhanced log daemon, supporting a wide range of input and output methods: syslog, unstructured text, message queues, databases (SQL and NoSQL alike) and more.

Key features:

• receive and send RFC3164 and RFC5424 style syslog messages
• work with any kind of unstructured data
• receive and send JSON formatted messages
• classify and structure logs with builtin parsers (csv-parser(), db-parser(), etc.)
• normalize, crunch and process logs as they flow through the system
• hand on messages for further processing using message queues (like AMQP), files or databases (like PostgreSQL or MongoDB).

This package provides the add-contextual-data module for syslog-ng. With this module syslog-ng can use an external database file to append custom name-value pairs on incoming logs (to enrich messages). The database is a file that containing <selector, name, value> records. Currently only CSV format is supported. It is like geoip parser where the selector is $HOST, but the user can define the selector, and also the database contents.
