启动

# /apache-skywalking-apm-incubating/bin

./startup.sh

 

客户端使用

默认情况下skywalking会加载/apache-skywalking-apm-incubating/agent/config/agent.config文件,也可以手动指定

 

jvm

java -javaagent:/apache-skywalking-apm-incubating/agent/skywalking-agent.jar 

     -Dskywalking.agent.service_name=trace-api 

     -Dskywalking.collector.backend_service=localhost:11800 

     -jar xxxx.jar

 

javaagent agent包路径

skywalking.agent.service_name 服务名称

skywalking.collector.backend_service 采集信息的服务地址 agent.config配置了就可以不用指定

agent.config配置

# The agent namespace

# agent.namespace=${SW_AGENT_NAMESPACE:default-namespace}

 

# The service name in UI

agent.service_name=${SW_AGENT_NAME:Your_ApplicationName}

 

# The number of sampled traces per 3 seconds

# Negative number means sample traces as many as possible, most likely 100%

# agent.sample_n_per_3_secs=${SW_AGENT_SAMPLE:-1}

 

# Authentication active is based on backend setting, see application.yml for more details.

# agent.authentication = ${SW_AGENT_AUTHENTICATION:xxxx}

 

# The max amount of spans in a single segment.

# Through this config item, skywalking keep your application memory cost estimated.

# agent.span_limit_per_segment=${SW_AGENT_SPAN_LIMIT:300}

 

# Ignore the segments if their operation names start with these suffix.

# agent.ignore_suffix=${SW_AGENT_IGNORE_SUFFIX:.jpg,.jpeg,.js,.css,.png,.bmp,.gif,.ico,.mp3,.mp4,.html,.svg}

 

# If true, skywalking agent will save all instrumented classes files in `/debugging` folder.

# Skywalking team may ask for these files in order to resolve compatible problem.

# agent.is_open_debugging_class = ${SW_AGENT_OPEN_DEBUG:true}

 

# Backend service addresses.

collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:127.0.0.1:11800}

 

# Logging level

logging.level=${SW_LOGGING_LEVEL:DEBUG}

 

手动追踪

pom添加

   <dependency>

      <groupId>org.apache.skywalking</groupId>

      <artifactId>apm-toolkit-trace</artifactId>

      <version>${skywalking.version}</version>

   </dependency>

 

java代码

    @GetMapping

    @Trace

    public String rest(String msg) {

        ActiveSpan.tag("args", "{msg:" + msg + "}");

        return helloService.say(msg);

    }

 

logback日志集成

pom添加

<dependency>

   <groupId>org.apache.skywalking</groupId>

   <artifactId>apm-toolkit-logback-1.x</artifactId>

   <version>{project.release.version}</version>

</dependency>

 

logback-spring.xml配置

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">

            <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout">

                <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%tid] [%thread] %-5level %logger{36} -%msg%n</Pattern>

            </layout>

        </encoder>

    </appender>

 

 

默认情况下输出TID: N/A 所以不用紧张
