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.
