A Java library providing Logback encoders, layouts, and appenders for logging in JSON and other Jackson-supported formats. Originally built for Logstash-compatible output, it has evolved into a highly configurable general-purpose structured logging mechanism.

Use cases

  • output logback logs in JSON format for logstash ingestion
  • configure structured logging for Java applications
  • send logs over TCP or UDP to a central log collector
  • customize which fields are included in JSON log events
  • log HTTP access events in JSON via logback-access
  • use async appenders with ring buffers for high-throughput logging

When to choose

  • you need JSON structured logging from a Java/JVM application using logback
  • you ship logs to Logstash, Elasticsearch, or other JSON-based log pipelines
  • you need fine-grained control over log event fields and output format

When to avoid

  • your application does not use logback as its logging framework
  • you only need simple human-readable text logs
  • you use a logging framework other than SLF4J/logback
