First of all, your program is going to write logs
Log logs to help you analyze the problem, logging only "parameter errors" such as the log is not helpful to solve the problem
Don't rely on exceptions, exceptions only deal with places you don't think about.
To record key parameters such as time of occurrence, execution time, log source, input parameter, output parameter, error code, exception stack information, etc.
environment support, because the client is using the Filebeat software, it does not rely on the Java environment, so do not need to install

From the discovery page, you can interactively explore the data for ES. Each document in each index that matches the selected index pattern can be accessed. You can submit search queries, filter search results, and view document data. You can also see the number of documents that match the search query and get the field valu
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 Lo

. Connect to Kibana with Elasticsearch
before you start using Kibana, you need to tell Kibana which Elasticsearch index you want to explore. The first time you visit Kibana, you are prompted to define an index pattern to match the names of one or more indexes.

Logstash + Kibana log system deployment configuration
Logstash is a tool for receiving, processing, and forwarding logs. Supports system logs, webserver logs, error logs, and application logs. In short, it includes all types of logs that can be flushed.
Typical use cases (ELK ):
Elasticsearch is used as the storage of background data, and kibana is used for front-end report presentation. Logstash acts as a
