Spring Boot集成syslog快速入门Demo

1.什么syslog？

Syslog-ng是由Balabit IT Security Ltd.维护的一套开源的Unix和类Unix系统的日志服务套件。它是一个灵活的、可伸缩的系统日志记录程序。对于服务器日志集中收集，使用它是一个不错的解决方案。syslog-ng (syslog-Next generation) 是syslog的升级版

Syslog-ng主要特性有：

支持SSL/TSL协议
支持将日志写入数据库中,支持的数据库有MySQL, Microsoft SQL (MSSQL),Oracle, PostgreSQL, and SQLite.
支持标准的syslog协议
支持filter、parse以及rewrite
支持更多的平台
更高的负载能力

2.环境准备

docker-compose.yml

version: '3.6'services:syslog:image: lscr.io/linuxserver/syslog-ng:latestcontainer_name: syslog-ngports:- 514:5514/udp- 601:6601/tcp- 6514:6514/tcpvolumes:- ./data/config:/config- ./data/log:/var/log #optionalrestart: unless-stopped

run

docker-compose -f docker-compose.yml up -d

down

docker-compose -f docker-compose.yml down

3.代码工程

实验目的

实现将springboot应用日志发送到syslog-ng

}
