log4j-redis-appender Build Status

Log4j appender for pushing log messages to a Redis list.

Derived from @pavlobaron's log4j2redis, though the two projects share almost no code. That project writes messages to unique keys as opposed to pushing to a list.

Configuration

This appender pushes log messages to a Redis list. Here is an example configuration:

log4j.rootLogger=DEBUG, redis
log4j.appender.redis=com.ryantenney.log4j.RedisAppender
log4j.appender.redis.layout=…
log4j.appender.redis.host=localhost
log4j.appender.redis.port=6379
log4j.appender.redis.password=password
log4j.appender.redis.key=key
log4j.appender.redis.period=500
log4j.appender.redis.batchSize=100
log4j.appender.redis.purgeOnFailure=true
log4j.appender.redis.alwaysBatch=true
log4j.appender.redis.daemonThread=true

Where:

  • key (required) key of the list to push log messages
  • host (optional, default: localhost)
  • port (optional, default: 6379)
  • password (optional) redis password, if required
  • period (optional, default: 500) the period in milliseconds between
  • batchSize (optional, default: 100) the number of log messages to send in a single RPUSH command
  • purgeOnFailure (optional, default: true) whether to purge the enqueued log messages if an error occurs attempting to connect to redis, thus preventing the memory usage from becoming too high
  • alwaysBatch (optional, default: true) whether to wait for a full batch. if true, will only send once there are batchSize log messages enqueued
  • daemonThread (optional, default: true) whether to launch the appender thread as a daemon thread

Maven

<dependency>
	<groupId>com.ryantenney.log4j</groupId>
	<artifactId>redis-appender</artifactId>
	<version>1.0.1</version>
</dependency>

Usage Note

Goes great with @lusis's log4j-jsonevent-layout for pushing log messages straight to a Logstash instance configured to ingest log messages from Redis. If you use Logstash with AMQP, check out @lusis's ZeroMQ Appender or @jbrisbin's RabbitMQ Appender
