centralize logging on CentOS 7 using Logstash and Kibana
Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location. It is also useful because it allows you to identify issues across multiple servers by associating their logs within a specific time frame. This series of tutorials will teach you how to install Logstash and

In addition to the basic projects, elk also do related migrations ....
Logstash say, the client only need to change the code logic Redis address on it, Logstash server directly docker pull mirroring on it.
Elasticsearch need to write our own script migration, because the Cross engine room import export, very time-consuming, about the migration of Elasticsearch, I write the next chapter, today's main write Kibana migration.
