SpringBoot整合sigar实现服务端监控,第1张

SpringBoot整合sigar实现服务端监控 sigar简介
  • Sigar全名是System Information Gatherer And Reporter，中文名是系统信息收集和报表的开源工具，它用来从许多平台收集系统和处理信息
  • sigar可以运行的平台：Linux，Windows，Mac OSX
  • https://github.com/hyperic/sigar/
  • 依赖汇编文件下载地址：https://sourceforge.net/projects/sigar/files/sigar/1.6/

由于sigar采集的信息时通过底层C语言来执行的，所以需要以下对应的依赖文件【依赖文件依据平台而定】

依赖文件下载地址：

Windows ：sigar-amd64-winnt.dll或sigar-x86-winnt.dll

Linux ：libsigar-amd64-linux.so或libsigar-x86-linux.so

MacOX ：libsigar-universal64-macosx.dylib或libsigar-universal-macosx.dylib

  • sigar可以搜集的信息

CPU信息：包括基本信息（vendor、model、mhz、cacheSize）和统计信息（user、sys、idle、nice、wait）
文件系统信息：包括Filesystem、Size、Used、Avail、Use%、Type
事件信息：类似Service Control Manager
内存信息：物理内存和交换内存的总数、使用数、剩余数；RAM的大小
网络信息：包括网络接口信息和网络路由信息
进程信息：包括每个进程的内存、CPU占用数、状态、参数、句柄
IO信息：包括IO的状态，读写大小等
服务状态信息
系统信息：包括 *** 作系统版本，系统资源限制情况，系统运行时间以及负载，JAVA的版本信息等

springboot整合sigar使用【以Linux系统为例】
  1. 首先pom.xml引入依赖包

    org.fusesource

  1. 通过controller写个demo

  1. ResourcePoolMonitorInfoclass文件内容
@Data
@NoArgsConstructor
@AllArgsConstructor
public class ResourcePoolMonitorInfo {
    
    private String ip;
    
    private String memTotal;
    
    private String memUsed;
    
    private String memUsedRate;
    
    private String memFree;
    
    private String memFreeRate;
    
    private String cpuCore;
    
    private String cpuUseRate;
    
    private String cpuSysRate;
    
    private String cpuIdleRate;
    
    private String cpuTotalRate;
}
  1. 将libsigar-amd64-linux.so或libsigar-x86-linux.so两个文件部署到linux下/usr/lib目录下

可以通过System.getProperty("java.library.path");查看java库的安装路径


5. 请求：http://ip:port/monitor 查看响应内容

  1. 返回指标与linux top命令比较

内存指标对比：
memTotal 对标 top中Mem total
memUsed对标 top中Mem used
memUsedRate对标 top中Mem used/total * 100
memFree对标 top中Mem free
memFreeRate对标 top中Mem free/total * 100
CPU指标对比：
cpuUseRate对标CPU中 us
cpuSysRate对标CPU中 sy
cpuIdleRate对标CPU中 id
cpuTotalRate = us + sy

另一种资源监控框架oshi介绍
  • OSHI.是一个基于JNA的免费的本地 *** 作系统和Java的硬件信息库。它不需要安装任何额外的本机库
  • 通过API可以获取到： *** 作系统版本、进程、内存和CPU使用情况、磁盘和分区、设备、传感器等信息

总结

Sigar 与OSHI都能够实现服务端资源监控，但是由于sigar是无法直接获取到 *** 作系统资源，所以需要通过C语言的汇编文件获取，从而 *** 作步骤会比较麻烦，相比于OSHI直接引入jar就可以获取硬件资源，若使用个人推荐OSHI
