docker-log-centralizer

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

Embedded containers

1. Filebeat - An agent to poll logs
2. Logstash-Forwarder - An other agent to poll logs
3. Logstash - The collector / analyzer / parser solution
4. Kafka - The queueing solution for logs
5. ZooKeeper - The cluster on which Kafka is running
6. ElasticSearch - The indexing engine
7. Kibana - The visualization / dashboard tool for ElasticSearch
8. Kafka Manager - The Kafka cluster web manager
9. Apache log generator - A container generating fake apache logs
10. Random log generator - A container genrating text logs (Star Wars quotes)

How it works

There are 2 agent types :

• Filebeat
• Logstash-Forward

These agents push logs (from the apache and random 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
