What is syslog-ng-mod-json
syslog-ng-mod-json 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 $(format-json) template function plugin, which makes it possible to conveniently serialize system log messages to JSON. Along with the template function, this module also provides a json-parser plugin, allowing syslog-ng to parse JSON input.
