#Docker log centralizer
|
|
This a end-to-end log centralizer powered by the ELK stask.
|
|
|
|
##Embedded containers
|
|
|
|
1. [Filebeat](https://www.elastic.co/products/beats/filebeat) - An agent to poll logs
|
|
2. [Logstash-Forwarder](https://github.com/elastic/logstash-forwarder) - An other agent to poll logs
|
|
3. [Logstash](https://www.elastic.co/products/logstash) - The collector / analyzer / parser solution
|
|
4. [Kafka](http://kafka.apache.org) - The queueing solution for logs
|
|
5. [ZooKeeper](https://zookeeper.apache.org/) - The cluster on which Kafka is running
|
|
6. [ElasticSearch](https://www.elastic.co/products/elasticsearch) - The indexing engine
|
|
7. [Kibana](https://www.elastic.co/products/kibana) - The visualization / dashboard tool for ElasticSearch
|
|
8. [Kafka Manager](https://github.com/yahoo/kafka-manager) - The Kafka cluster web manager
|
|
9. [Apache log generator](https://github.com/Febbweiss/docker-apache-log-generator) - A container generating fake apache logs
|
|
10. [Random log generator](https://hub.docker.com/r/davidmccormick/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
|
|
```
|
|
|
|
