docker-log-centralizer

This a end-to-end log centralizer powered by the ELK stask.

Embedded containers

• Filebeat - An agent to poll logs
• Logstash-Forwarder - An other agent to poll logs
• rsyslog - A standard Linux log manager
• Logstash - The collector / analyzer / parser solution
• Kafka - The queueing solution for logs
• ZooKeeper - The cluster on which Kafka is running
• ElasticSearch - The indexing engine
• Kibana - The visualization / dashboard tool for ElasticSearch
• Kafka Manager - The Kafka cluster web manager
• Apache log generator - A container generating fake apache logs
• Random log generator - A container generating text logs (Star Wars quotes)
• Java log generator - A container generating Java logs (with exception stack trace)

How it works

There are 3 agent types :

• Filebeat
• Logstash-Forward
• rsyslog

These agents push logs (from the generators) to a Logstasth shipper filling a Kafka queue (one type of log for one topic). A Logstash indexer polls the Kafka topics indexing logs into a ElasticSearch.

A short schema :

Agent -> Logstach shipper -> Kafka <- Logstash indexer -> ElasticSearch
