우선 연습하다 발생한 log들을 저장하기 위해 morgan 모듈을 설치하여
app,js에 이와같이 선언해주었습니다.
const logger = require('morgan')
app.use(logger('dev'));
artillery 모듈은 가상으로 사용자 수를 지정하여 서버에 과부하가 걸리는지 테스트합니다.
artillery 모듈을 설치하고 cpu-test.yaml 파일을 생성하여 이와 같이 작성했습니다.
config:
target: "http://localhost:8080" # host
phases:
- duration: 30 # 해당 초만큼 실행
arrivalRate: 3000 # 가상 사용자 수
scenarios:
- flow:
- get:
url: "/user" # setParam에서 넣은 ID
capture:
json:
as:
app.js에
app.get('/user', (req, res) => {
res.send('테스트');
});
이와 같은 api를 작성하였는데 해당 프로젝트가 아닌 다른 프로젝트에도 적용하여 테스트가 가능합니다.
모듈을 글로벌이 아닌 로컬에 설치하였기 때문에, json에 따로 명령어를 만들어주었습니다.
{

"version": "0.0.1",
"description": "트래픽 테스트",

"report": "./node_modules/.bin/artillery run -o loadbalancing-report cpu-test.yaml",
"pm2": "pm2 start app.js -i 0",
"kill": "pm2 kill"
}
}
아래의 명령어를 입력하여 서버를 테스트해보았습니다.
npm run artillery
npm run report
그러면 콘솔에 이러한 결과가 찍히게 됩니다.

Errors가 아니라 Codes : 200이 나와야 정상입니다.
의도적으로 서버에 과부하를 걸어준 것은 맞으나 고작 3000명에 터지는 서버라니..비실비실하군요...
어찌되었건 과부하 걸린 서버를 pm2를 이용하여 조금이나마 줄여보도록 하겠습니다.
pm2 모듈을 설치 후 실행시킬 건데요 명령어는 위에서 올린 package.json에 적어두었습니다.
npm run pm2 // 키기
npm run kill //끄기
pm2의 장점은 로드밸린성 최적화와 무중단으로 서버를 돌릴 수 있다는 장점이 있죠.
실행시켜보면
이제 이 상태로 다시 artillery를 실행시켜보겠습니다...
