Linux 명령어 - systemd-cgtop 서비스 그룹별 모니터링

Linux 명령어 - systemd-cgtop 서비스 그룹별 모니터링 

 

 

 

이번 포스팅에서는 리눅스에서 서비스 그룹별로 모니터링에 대해서 알아보도록 하겠습니다.

 

 

Linux systemd-cgtop 서비스 그룹별 모니터링

 

 

systemd에 의해서 실행된 서비스들을 그룹별로 CPU 사용량, 메모리 사용량, 프로세스 개수 등을 실시간으로 간편히 모니터링할 수 있습니다.

 

 

# systemd-cgtop

 

 

systemd-cgtop 명령어를 입력하면 아래의 내용과 같이 실시간으로 모니터링할 수 있습니다.
