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 Kibana on CentOS, and then how to add more filters to construct your log data.
, sorting and statistics and the large number of machines still use such a method is a little too hard.

The system transportation and the development personnel can through the log to understand the server hardware and software information, examines the configuration process the error and the error occurrence reason. Regular analysis of the log can understand the server load, performance security, so as to take timely measures to correct errors. The role of the log is self-evident, but for a large number of logs distributed across multiple machines, viewing is particularly troublesome. Therefore, t

are as follows:
For example, the/home/husen/config/directory has
//in1.conf, in2.conf, filter1.conf, filter2.conf, out.conf these 5 files
//We use/ Logstash-5.5.1/bin/logstash-f/home/husen/config boot Logtstash
//logstash automatically loads this 5 configuration file and merges it into 1 whole profiles
2, Logstash multiple configuration files in the input, filter, output is independent of each other
The answer: NO.
Like what:
# # IN1.CONF content is as follows:
