Elastic-search, Logstash, and Kibana is know as ELK stack.

This ELK stack is opensource stack, where E stands for Elastic serach, L– logstash and K stands for Kibana.

Below diagram will explain show this ELK stack is used in organization, with the help of logstash we can collect the data of any application put into elastic search and via elastic search same can be visualized at kibana desk board.

I hope from above diagram give you the better understanding how it work so let deep drive how to configure this stack, so that it will be help full to understand.

Before continuing to this post (Let me thanks to my friends or team member who explain me this in such a way I can configure this couple of hours at my server.) So let me share how I configure

Elastic Search Configuration:

Elastic Search:

Install elastic search:-

Download package from https://www.elastic.co/downloads/elasticsearch

If you want to run from anywhere in that case set the path in .bash_profile.

Start the elasticsearch ELK stacks

start the elastic search

./elastic_search shaktidevops@instance-4:~$ curlhttps://ssh.cloud.google.com/devshell/proxy?authuser=0&devshellProxyPath=%2F&port=9200" http://localhost:9200/
