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.

important information, it is still using the traditional method, to log on to a machine to view. It seems that the traditional tools and methods have become very clumsy and inefficient. As a result, some smart people put forward a centralized approach to integrating data from different sources into one place. A complete centralized log system is inseparable from the following key features. Collection-capable of capturing log data from multiple sources-can reliably transfer logs to a central sys

not_analyzedElasticsearch automatically uses its own default word breakers (spaces, dots, slashes, and so on) to analyze fields. A word breaker is very important for searching and scoring, but it greatly reduces the performance of index write and aggregate requests. So the Logstash template defines a field called a "multi-field" (Multi-field) type, and sets the field to not enable the word breaker. That is, when you want to get the aggregated result of the URL field, do not use "url" directly,
