SpringBoot之actuator

在springBoot中集成actuator可以很方便的管理和监控应用的状态。

暴露的Restful接口有：

HTTP方法路径描述鉴权
GET /autoconfig 查看自动配置的使用情况 true
GET /configprops 查看配置属性，包括默认配置 true
GET /beans 查看bean及其关系列表 true
GET /dump 打印线程栈 true
GET /env 查看所有环境变量 true
GET /env/{name} 查看具体变量值 true
GET /health 查看应用健康指标 false
GET /info 查看应用信息 false
GET /mappings 查看所有url映射 true
GET /metrics 查看应用基本指标 true
GET /metrics/{name} 查看具体指标 true
POST /shutdown 关闭应用 true
GET /trace 查看基本追踪信息 true

其中有不少请求需要鉴权才能访问，由于我们的应用基本都是在通过Nginx暴露给外网的，我们可以在配置文件禁用鉴权拦截。

# 禁用actuator管理端鉴权
management.security.enabled=false
# 启用shutdown   host:port/shutdown
endpoints.shutdown.enabled=true
# 禁用密码验证
endpoints.shutdown.sensitive=false

通过访问http://IP:port/metrics可以得到类似如下信息：

如果只关心某部分参数可以使用：http://IP:port/metrics/mem来查看特定参数的值

{"mem":373311}
