Skywalking的性能损耗接近3%
一. Docker配置
- docker pull apache/skywalking-oap-server:9.4.0-java17
- docker pull apache/skywalking-ui:v9.4.0-java17
- docker pull elasticsearch:8.7.1
- docker pull kibana:8.7.1
docker run --name elasticsearch --network rootnet --ip 172.19.0.8 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx512m" -e xpack.security.enabled=false -d elasticsearch:8.7.1. 存储oap收集的数据docker run --name skywalking-oap --network rootnet --ip 172.19.0.9 --restart always -d -p 11800:11800 -p 12800:12800 --privileged=true -e TZ=Asia/Shanghai -e SW_STORAGE=elasticsearch -e SW_STORAGE_ES_CLUSTER_NODES=172.19.0.8:9200 -e SW_CLUSTER_INTERNAL_COM_HOST=172.19.0.9 -e SW_CLUSTER_INTERNAL_COM_PORT=11800 -e SW_CLUSTER=nacos -e SW_CLUSTER_NACOS_HOST_PORT=172.19.0.5:8848 -e SW_CLUSTER_NACOS_NAMESPACE=19a0fa32-ed2e-40f1-a1e1-aae8c81d8cf8 -e SW_CLUSTER_NACOS_USERNAME=nacos -e SW_CLUSTER_NACOS_PASSWORD=nacos -v /etc/localtime:/etc/localtime:ro apache/skywalking-oap-server:9.4.0-java17. (负责收集和处理来自Agent的数据，并将其存储到可选的存储系统中（例如Elasticsearch或TiDB）。因此，SkyWalking OAP可以看作是SkyWalking的数据集中器)docker run --name skywalking-ui --network rootnet --ip 172.19.0.10 --restart always -p 7099:8080 -d --privileged=true -e TZ=Asia/Shanghai -e SW_OAP_ADDRESS=[http://172.19.0.9:12800](http://172.19.0.9:12800) -v /etc/localtime:/etc/localtime:ro apache/skywalking-ui:v9.4.0-java17.docker run --name kibana -d --network rootnet --ip 172.19.0.11 -p 5601:5601 -v /usr/local/kibana/config/:/usr/share/kibana/config/ kibana:8.7.1. /usr/local/kibana/config下有两个配置文件
server.host: "0.0.0.0"
server.shutdownTimeout: "5s"
elasticsearch.hosts: [ "http://172.19.0.8:9200" ]
monitoring.ui.container.elasticsearch.enabled: true## Node command line options
## See `node --help` and `node --v8-options` for available options
## Please note you should specify one option per line
## max size of old space in megabytes
#--max-old-space-size=4096
## do not terminate process on unhandled promise rejection
--unhandled-rejections=warn- kibana中, 点击 discover, 点击 Create a data view. Index pattern 输入 sw_log
二. Java配置
- 配置agent.
-javaagent:/path/skywalking-agent.jar -Dskywalking.agent.service_name=user-api -Dskywalking.collector.backend_service=192.168.222.129:11800. user-api是当前服务的名称. 192.168.222.129:11800是oap服务grpc地址 - 配置日志传输.
添加依赖
<dependency>
<groupId>org.apache.skywalking</groupId>
<artifactId>apm-toolkit-logback-1.x</artifactId>
<version>{project.release.version}</version>
</dependency>logback-spring.xml如下
<!-- 传输到skywalking -->
<appender name="skywalking-log" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender">
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.mdc.TraceIdMDCPatternLogbackLayout">
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%X{tid}] [%thread] %-5level %logger{36} -%msg%n</pattern>
</layout>
</encoder>
</appender>
<root level="info">
<appender-ref ref="skywalking-log"/>
</root>效果图

不支持添加log字段. 日志模块完全可以使用ELK代替, 将TraceID复制出来后放在ELK中再查询. 将日志再传输至skywalking也会带来一定的损耗
