sentinel-报fetch-metric解决方法

  sentinel报fetchmetric解决方法  1.今天在本地搭建sentinel，发现发送请求后，在sentinel控制台监控不到发送的请求，查看sentinel控制后发现报如下错误： 2021-02-2514:31:58.024ERROR26384---[pool-2-thread-1]c.a.c.s.dashboard.metric.MetricFetcher:fetchmetrichttp://10.11.13.82:8720/metric?startTime=1614234702000&endTime=1614234708000&refetch=falseerrorjava.net.SocketException:Permissiondenied:nofurtherinformationatsun.nio.ch.SocketChannelImpl.checkConnect(NativeMethod)~[na:1.8.0_281]atsun.nio.ch.SocketChannelImpl.finishConnect(UnknownSource)~[na:1.8.0_281]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvent(DefaultConnectingIOReactor.java:171)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvents(DefaultConnectingIOReactor.java:145)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor.execute(AbstractMultiworkerIOReactor.java:348)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.conn.PoolingNHttpClientConnectionManager.execute(PoolingNHttpClientConnectionManager.java:194)[httpasyncclient-4.1.3.jar!/:4.1.3]atorg.apache.http.impl.nio.client.CloseableHttpAsyncClientBase$1.run(CloseableHttpAsyncClientBase.java:64)[httpasyncclient-4.1.3.jar!/:4.1.3]atjava.lang.Thread.run(UnknownSource)[na:1.8.0_281]2021-02-2514:31:58.964ERROR26384---[pool-2-thread-1]c.a.c.s.dashboard.metric.MetricFetcher:fetchmetrichttp://10.11.13.82:8720/metric?startTime=1614234709000&endTime=1614234715000&refetch=falseerrorjava.net.SocketException:Permissiondenied:nofurtherinformationatsun.nio.ch.SocketChannelImpl.checkConnect(NativeMethod)~[na:1.8.0_281]atsun.nio.ch.SocketChannelImpl.finishConnect(UnknownSource)~[na:1.8.0_281]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvent(DefaultConnectingIOReactor.java:171)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvents(DefaultConnectingIOReactor.java:145)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor.execute(AbstractMultiworkerIOReactor.java:348)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.conn.PoolingNHttpClientConnectionManager.execute(PoolingNHttpClientConnectionManager.java:194)[httpasyncclient-4.1.3.jar!/:4.1.3]atorg.apache.http.impl.nio.client.CloseableHttpAsyncClientBase$1.run(CloseableHttpAsyncClientBase.java:64)[httpasyncclient-4.1.3.jar!/:4.1.3]atjava.lang.Thread.run(UnknownSource)[na:1.8.0_281]2021-02-2514:31:59.504ERROR26384---[pool-1-thread-1]c.a.c.s.d.client.SentinelApiClient:HTTPrequestfailed:http://10.11.13.82:8720/jsonTree?type=rootjava.net.SocketException:Permissiondenied:nofurtherinformationatsun.nio.ch.SocketChannelImpl.checkConnect(NativeMethod)~[na:1.8.0_281]atsun.nio.ch.SocketChannelImpl.finishConnect(UnknownSource)~[na:1.8.0_281]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvent(DefaultConnectingIOReactor.java:171)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvents(DefaultConnectingIOReactor.java:145)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor.execute(AbstractMultiworkerIOReactor.java:348)[httpcore-nio-4.4.6.jar!/:4.4.6]atorg.apache.http.impl.nio.conn.PoolingNHttpClientConnectionManager.execute(PoolingNHttpClientConnectionManager.java:194)[httpasyncclient-4.1.3.jar!/:4.1.3]atorg.apache.http.impl.nio.client.CloseableHttpAsyncClientBase$1.run(CloseableHttpAsyncClientBase.java:64)[httpasyncclient-4.1.3.jar!/:4.1.3]atjava.lang.Thread.run(UnknownSource)[na:1.8.0_281]2021-02-2514:31:59.505ERROR26384---[nio-8080-exec-7]c.a.c.s.d.client.SentinelApiClient:Errorwhenfetchingitemsfromapi:jsonTree->rootjava.util.concurrent.ExecutionException:java.net.SocketException:Permissiondenied:nofurtherinformationatjava.util.concurrent.CompletableFuture.reportGet(UnknownSource)~[na:1.8.0_281]atjava.util.concurrent.CompletableFuture.get(UnknownSource)~[na:1.8.0_281]atcom.alibaba.csp.sentinel.dashboard.client.SentinelApiClient.fetchItems(SentinelApiClient.java:374)[classes!/:na]atcom.alibaba.csp.sentinel.dashboard.client.SentinelApiClient.fetchResourceOfMachine(SentinelApiClient.java:441)[classes!/:na]atcom.alibaba.csp.sentinel.dashboard.controller.ResourceController.fetchResourceChainListOfMachine(ResourceController.java:70)[classes!/:na]2.这个是因为sentinel发送客户端心跳失败了，查看了我的本地ip地址发现sentinel获取的ip地址不对，所以在配置文件中指点一下clientIp，我的配置如下：server:port:8401spring:application:name:cloudalibab-sentinel-servicecloud:nacos:discovery:server-addr:localhost:8848sentinel:transport:dashboard:localhost:8080port:8719clientIp:localhostmanagement:endpoints:web:exposure:include:'*'3.在次重启sentinel控制台和微服务，发现不会报错了，服务接口也成功监控到了 -全文完-
