使用Actuator监控Spring Boot应用

我们都知道Spring Boot是一个用于快速开发Java Web的框架,不需要太多的配置即可使用Spring的大量功能。Spring Boot遵循着“约定大于配置”的原则,许多功能使用默认的配置即可。这样的做法好处在于我们不需要像使用Spring那样编写一大堆的XML配置代码,但过于简单的配置过程会让我们在了解各种依赖,配置之间的关系过程上带来一些困难。不过没关系,在Spring Boot中,我们可以使用Actuator来监控应用,Actuator提供了一系列的RESTful API让我们可以更为细致的了解各种信息。

server:
port: 80

management:
security:
enabled: false #关掉安全认证
port: 80
context-path: /monitor #actuator的访问路径
endpoints:
shutdown:
enabled: true

配置中关闭了安全认证的功能,如果需要开启这个功能的话还需引入spring-boot-starter-security依赖。除了使用Spring Security来开启监控路径安全认证外,还可以使用Shiro对监控路径进行权限控制。

监控的端口和应用一致,配置context-path/monitor,这样可以避免和自己应用的路径映射地址重复。

endpoints.shutdown.enabled: true提供了使用post请求来关闭Spring Boot应用的功能。

Actuator接口列表

Actuator提供了13个接口,可以分为三大类:配置接口、度量接口和其它接口,具体如下表所示:

HTTP 方法路径描述
GET/autoconfig提供了一份自动配置报告,记录哪些自动配置条件通过了,哪些没通过
GET/configprops描述配置属性(包含默认值)如何注入Bean
GET/beans描述应用程序上下文里全部的Bean,以及它们的关系
GET/dump获取线程活动的快照
GET/env获取全部环境属性
GET/env/{name}根据名称获取特定的环境属性值
GET/health报告应用程序的健康指标,这些值由HealthIndicator的实现类提供
GET/info获取应用程序的定制信息,这些信息由info打头的属性提供
GET/mappings描述全部的URI路径,以及它们和控制器(包含Actuator端点)的映射关系
GET/metrics报告各种应用程序度量信息,比如内存用量和HTTP请求计数
GET/metrics/{name}报告指定名称的应用程序度量值
POST/shutdown关闭应用程序,要求endpoints.shutdown.enabled设置为true
GET/trace提供基本的HTTP请求跟踪信息(时间戳、HTTP头等)

接口使用示例

autoconfig

/metrics接口提供的信息进行简单分类如下表:

分类前缀报告内容
垃圾收集器gc.已经发生过的垃圾收集次数,以及垃圾收集所耗费的时间,适用于标记-清理垃圾收集器和并行垃圾收集器(数据源自java.lang.management. GarbageCollectorMXBean)
内存mem.分配给应用程序的内存数量和空闲的内存数量(数据源自java.lang. Runtime)
heap.当前内存用量(数据源自java.lang.management.MemoryUsage)
类加载器classes.JVM类加载器加载与卸载的类的数量(数据源自java.lang. management.ClassLoadingMXBean)
系统processors、instance.uptime、uptime、systemload.average系统信息,例如处理器数量(数据源自java.lang.Runtime)、运行时间(数据源自java.lang.management.RuntimeMXBean)、平均负载(数据源自java.lang.management.OperatingSystemMXBean)
线程池thread.线程、守护线程的数量,以及JVM启动后的线程数量峰值(数据源自 java.lang .management.ThreadMXBean)
数据源datasource.数据源连接的数量(源自数据源的元数据,仅当Spring应用程序上下文里存在 DataSource Bean 的时候才会有这个信息)
Tomcat 会话httpsessions.*Tomcat的活跃会话数和最大会话数(数据源自嵌入式Tomcat的Bean,仅在使用嵌入式Tomcat服务器运行应用程序时才有这个信息)
HTTPcounter.status.、gauge.response.多种应用程序服务HTTP请求的度量值与计数器

HTTP的计数器和度量值需要做一点说明。counter.status后的值是HTTP状态码,随后是所请求的路径。举个例子,counter.status.200.metrics 表明/metrics端点返回 200(OK) 状态码的次数。

HTTP的度量信息在结构上也差不多,却在报告另一类信息。它们全部以gauge.response开头,表明这是HTTP响应的度量信息。前缀后是对应的路径。度量值是以毫秒为单位的时间,反映了最近处理该路径请求的耗时。

这里还有几个特殊的值需要注意。root路径指向的是根路径或/star-star代表了那些Spring认为是静态资源的路径,包括图片、JavaScript和样式表,其中还包含了那些找不到的资源。这就是为什么你经常会看到counter.status.404.star-star,这是返回了HTTP 404 (NOT FOUND)状态的请求数。

/metrics接口会返回所有的可用度量值,但你也可能只对某个值感兴趣。要获取单个值,请求时可以在URL后加上对应的键名。例如,要查看空闲内存大小,可以向/metrics/mem.free发一个GET请求。

定制Actuator

修改接口ID

每个Actuator接口都有一个ID用来决定接口的路径,比方说,/beans接口的默认ID就是beans。比如要修改/beans/instances,则设置如下:

1
2
3
endpoints:
beans:
id: instances

启用和禁用接口

虽然Actuator的接口都很有用,但你不一定需要全部这些接口。默认情况下,所有接口(除了/shutdown)都启用。比如要禁用 /metrics 接口,则可以设置如下:

1
2
3
endpoints:
metrics:
enabled: false

如果你只想打开一两个接口,那就先禁用全部接口,然后启用那几个你要的,这样更方便。

1
2
3
4
endpoints:
enabled: false
metrics:
enabled: true
