監(jiān)控和管理端點(diǎn)
端點(diǎn)名 | 描述 |
---|---|
autoconfig | 所有自動配置信息( positiveMatches :運(yùn)行的, negativeMatches 未運(yùn)行組件) |
auditevents | 審計(jì)事件 |
beans | 所有Bean的信息 |
configprops | 所有配置屬性 |
dump | 線程狀態(tài)信息 |
env | 當(dāng)前環(huán)境信息 |
health | 應(yīng)用健康狀況 |
info | 當(dāng)前應(yīng)用信息 |
metrics | 應(yīng)用的各項(xiàng)指標(biāo) |
mappings | 應(yīng)用@RequestMapping映射路徑 |
shutdown | 關(guān)閉當(dāng)前應(yīng)用(默認(rèn)關(guān)閉) |
trace | 追蹤信息(最新的http請求) |
heapdump | 下載內(nèi)存快照 |
http://localhost:8083/info 讀取配置文件application.properties的 info.*屬性
在InfoProperties 讀取
application.properties :
info.app.version=v1.2.0info.app.name=abc
在GitProperties 獲取git.properties 的信息
info.app.version=v1.2.0info.app.name=abc#遠(yuǎn)程關(guān)閉開啟endpoints.shutdown.enabled=true #訪問:http://localhost:8083/shutdown 關(guān)閉服務(wù)

org.springframework.boot.actuate.health 包下對于所有的健康狀態(tài)檢查例如:RedisHealthIndicator ,當(dāng)有redis的starter 時(shí)候就會檢查
{ status: "DOWN", //狀態(tài) diskSpace: { status: "UP", total: 395243941888, free: 367246643200, threshold: 10485760 }, rabbit: { status: "DOWN", error: "org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect" }, redis: { status: "UP", version: "4.0.9" }, db: { status: "UP", database: "MySQL", hello: 1 }}
自定義health
•自定義健康狀態(tài)指示器
•1、編寫一個(gè)指示器 實(shí)現(xiàn) HealthIndicator 接口
•2、指示器的名字 xxxxHealthIndicator
•3、加入容器中
import org.springframework.boot.actuate.health.Health;import org.springframework.boot.actuate.health.HealthIndicator;import org.springframework.stereotype.Component;@Componentpublic class MyAppHealthIndicator implements HealthIndicator {? @Override public Health health() {? //自定義的檢查方法 //Health.up().build()代表健康 return Health.down().withDetail("msg","服務(wù)異常").build(); }}
