[ Database ] redis info 사용법 (Python 예제)

이번 포스팅에서는 redis info 명령에 대해서 알아보도록 하겠습니다.

 

< redis-cli >

 

info memory

 

 

< python >

 

- Python redis info 예제 코드 - 메모리 확인 

import redis

def connect_redis():

    try:

        conn = redis.StrictRedis(host=redis_info['host'], port=redis_info['port'], db=redis_info['db'])



    except Exception as e:

        print("DB connection error: ", e)

    return conn





def info_redis():

    conn = connect_redis()

    result = conn.info(section='memory')

    print(result)



info_redis()

 

 

- 결과
