DigitialOcean ELK Stack
The DigitalOcean ELK Stack One-Click Application provides you with a quick way to launch a centralized logging server. The ELK Stack is made up of three key pieces of software: Elasticsearch, Logstash, and Kibana. Together they allow you to collect, search, and analyze logs files from across your infrastructure. Logstash collects and parses the incoming logs, Elasticsearch indexes them, and Kibana gives you a powerful web interface to visualize the data.
This tutorial will show you how to launch an ELK instance and set up Logstash Forwarder on your other servers to send their logs to your new centralized logging server.
