Jaeger란 무엇인가?

Jaeger 실습

1) Jaeger 서버

- jaeger 다운로드 및 압축 해제

wget https://github.com/jaegertracing/jaeger/releases/download/v1.66.0/jaeger-2.3.0-linux-amd64.tar.gz

tar zxvf jaeger-2.3.0-linux-amd64.tar.gz

- 폴더 이동 후 실행

cd jaeger-2.3.0-linux-amd64

./jaeger

- 클라이언트에서 접속 가능하도록 bind address 환경 변수 변경

export JAEGER_LISTEN_HOST=0.0.0.0

- 16686포트로 접속

2) 백엔드(Spring) 서버

- Spring Boot 애플리케이션에서 Jaeger 분산 추적 시스템을 설정하는 코드 작성

JaegerConfig.java

package com.example.jaeger.config;

import io.jaegertracing.Configuration;
import io.jaegertracing.internal.JaegerTracer;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

@Component
public class JaegerConfig {
    @Bean
    public JaegerTracer jaegerTracer() {
        Configuration.SamplerConfiguration samplerConfig = Configuration.SamplerConfiguration.fromEnv().withType("const").withParam(1);

        Configuration.SenderConfiguration udpSender = Configuration.SenderConfiguration.fromEnv().withAgentHost("[Jaeger Server IP]");

        Configuration.ReporterConfiguration reporterConfig= Configuration.ReporterConfiguration.fromEnv().withLogSpans(true).withSender(udpSender);

        Configuration config = new Configuration("My Project").withSampler(samplerConfig).withReporter(reporterConfig);

        return config.getTracer();
    }
}

핀포인트(Pinpoint)란?

실습 방법

1) 저장소 및 Web 서버 설정

1. 자바 설치

apt update

apt install -y openjdk-8-jdk

2. HBase 다운로드 및 압축 해제

wget https://archive.apache.org/dist/hbase/1.2.7/hbase-1.2.7-bin.tar.gz

tar zxvf hbase-1.2.7-bin.tar.gz

3. HBase 환경 변수 수정

vi ./hbase-1.2.7/conf/hbase-env.sh

------------------------------------------------------

# 28번 라인 수정
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

# 44, 47, 48 라인 주석 처리 
# export HBASE_OPTS="-XX:+UseConcMarkSweepGC"
# export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -XX:Per    mSize=128m -XX:MaxPermSize=128m -XX:ReservedCodeCacheS    ize=256m"
# export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_    OPTS -XX:PermSize=128m -XX:MaxPermSize=128m -XX:Reserv    edCodeCacheSize=256m"

4. HBase 실행

./hbase-1.2.7/bin/start-hbase.sh

• HBase 마스터와 리전 서버를 시작. 이 과정에서 ZooKeeper도 함께 시작됨(기본적으로 HBase 1.2.7은 번들 ZooKeeper 포함).

5. HBase 테이블 생성 스크립트 다운로드 및 테이블 생성

wget https://raw.githubusercontent.com/pinpoint-apm/pinpoint/master/hbase/scripts/hbase-create.hbase

./hbase-1.2.7/bin/hbase shell ./hbase-create.hbase

6. Pinpoint Collector 다운로드 및 실행

wget https://github.com/pinpoint-apm/pinpoint/releases/download/v2.3.3/pinpoint-collector-boot-2.3.3.jar

nohup java -jar -Dpinpoint.zookeeper.address=localhost pinpoint-collector-boot-2.3.3.jar > collector.log 2> collector-error.log &

7. Pinpoint Web 다운로드 및 실행

wget https://github.com/pinpoint-apm/pinpoint/releases/download/v2.3.3/pinpoint-web-boot-2.3.3.jar

nohup java -jar -Dpinpoint.zookeeper.address=localhost pinpoint-web-boot-2.3.3.jar > web.log 2> web-error.log &

8. 8080 포트로 Pinpoint Web 접속

2) Agent 설정

1. 자바 설치

apt update

apt install -y openjdk-17-jdk

2. Pinpoint Agent다운로드 및 압축해제

wget https://repo1.maven.org/maven2/com/navercorp/pinpoint/pinpoint-agent/3.0.1/pinpoint-agent-3.0.1.tar.gz

tar zxvf pinpoint-agent-3.0.1.tar.gz

3. Pinpoint Agent 환경 설정에서 collector IP 주소 변경

vi ./pinpoint-agent-3.0.1/profiles/release/pinpoint.config

----------------------------------------------------

#23번 라인 수정
profiler.transport.grpc.collector.ip=[Pinpoint Collector IP Adress]

4. Pinpoint Agent와 함께 배포한 백엔드 서버(java) 실행

java -jar \
  -javaagent:/root/pinpoint-agent-3.0.1/pinpoint-bootstrap-3.0.1.jar \
  -Dpinpoint.agentId=my-project \
  -Dpinpoint.applicationName=spring-server \
backend-ver-SNAPSHOT.jar
