Hi Team,

I am planning to implement ELK to one of my application for log analysis. i would like to know what will be stored in elastic storage ? how to estimate the elastic storage capacity requirement? does the log files make a copy from client server(where the file beat installed and logs exists) to ELK server (where elastic search, kibana, logstash installed) and store in elastic search space(path.data)?

Thanks  
Nikhil

Hi @nikhilesh,

the file is not stored as is, rather it is parsed and indexed to allow fast searches. Also, a deployment would typically have replicas of data for high availability. On the other hand, data is compressed when stored in Elasticsearch.

I would recommend doing a prototype to find out the approximate storage needs.
