可以通过API接口监控和管理服务的提供者：

1.展示所有的提供者的注册信息：

http://localhost:7001/eureka/apps

返回结果如下

<application>
    <name>SPRING-CLOUD-PRODUCTER2-002</name>
    <instance>
    <instanceId>DESKTOP-PO54VO9:spring-cloud-producter2-002:8002</instanceId>
    <hostName>DESKTOP-PO54VO9</hostName>
    <app>SPRING-CLOUD-PRODUCTER2-002</app>
    <ipAddr>192.168.25.46</ipAddr>
    <status>UP</status>
    <overriddenstatus>UNKNOWN</overriddenstatus>
    <port enabled="true">8002</port>
    <securePort enabled="false">443</securePort>
    <countryId>1</countryId>
    <dataCenterInfo class="com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo">
    <name>MyOwn</name>
    </dataCenterInfo>
    <leaseInfo>
    <renewalIntervalInSecs>30</renewalIntervalInSecs>
    <durationInSecs>90</durationInSecs>
    <registrationTimestamp>1541665321451</registrationTimestamp>
    <lastRenewalTimestamp>1541665531526</lastRenewalTimestamp>
    <evictionTimestamp>0</evictionTimestamp>
    <serviceUpTimestamp>1541665321451</serviceUpTimestamp>
    </leaseInfo>
    <metadata>
    <management.port>8002</management.port>
    <jmx.port>53608</jmx.port>
    </metadata>
    <homePageUrl>http://DESKTOP-PO54VO9:8002/</homePageUrl>
    <statusPageUrl>http://DESKTOP-PO54VO9:8002/actuator/info</statusPageUrl>
    <healthCheckUrl>http://DESKTOP-PO54VO9:8002/actuator/health</healthCheckUrl>
    <vipAddress>spring-cloud-producter2-002</vipAddress>
    <secureVipAddress>spring-cloud-producter2-002</secureVipAddress>
    <isCoordinatingDiscoveryServer>false</isCoordinatingDiscoveryServer>
    <lastUpdatedTimestamp>1541665321451</lastUpdatedTimestamp>
    <lastDirtyTimestamp>1541665321427</lastDirtyTimestamp>
    <actionType>ADDED</actionType>
    </instance>
    </application>

**2.根据appid获取该实例的基本信息：**

http://localhost:7001/eureka/apps/SPRINGCLOUD-EUREKA-CLIENT-008

**3.设置覆盖状态,暂停应用实例，可以用来做强制实例下线**

接口地址：

http://localhost:7001/eureka/apps/appID/instanceID/status?value=OUT_OF_SERVICE

调用方式：PUT

demo：[http://127.0.0.1:7001/eureka/apps/SPRINGCLOUD-EUREKA-CLIENT-008/springcloud-eureka-client-008/status?value=OUT\_OF\_SERVICE][http_127.0.0.1_7001_eureka_apps_SPRINGCLOUD-EUREKA-CLIENT-008_springcloud-eureka-client-008_status_value_OUT_OF_SERVICE]

当提供者都 暂停后 此时消费者通过eureka调用提供者时掉不通的

**4.删除覆盖状态接口地址： /eureka/apps/appID/instanceID/status?value=UP**

调用方式：**DELETE**

接口说明：删除实例的覆盖状态 ， 可以恢复因设置了覆盖状态的实例上线

调用说明：

地址：[http://127.0.0.1:7001/eureka/apps/SPRINGCLOUD-EUREKA-CLIENT-008/springcloud-eureka-client-008\_2/status?value=UP][http_127.0.0.1_7001_eureka_apps_SPRINGCLOUD-EUREKA-CLIENT-008_springcloud-eureka-client-008_2_status_value_UP]

**5.服务下线**

接口地址： /eureka/apps/appID/instanceID

调用方式：DELETE

返回状态：HTTPCode: 200 为成功

接口说明：调用该接口，可以直接将服务下线。注意!!!下次心跳又会注册上来。
