In this blog, i will summarize about ELK, Before going further let me answer why you need a log aggregation solution. With Cloud native applications running multiple Micro services, with their own lifecycle and log mechanism debugging a production issue is a nightmare without a centralized log aggregation solution
ELK consists of 3 open source products
E - Elastic NO SQL database
L - Logstash log pipeline tool that ingests logs from diff sources and send them over to Elastic
K - Kibana visualization tool to view aggregated logs
Pretty straight forward to use from an application developer's perspective, all you need is some config changes in terms of pointing your application configuration to the elastic endpoint and port
