gnocchi plicy 옵션 

gnocchi archive-policy create -d points:10,granularity:0:01:00,timespan:0:10:00 -m sum -m std -m count -m min -m mean -m max -m rate:mean (생성 명령어)

d <DEFINITION>

1. timespan – 메트릭이 집계를 유지하는 시간
2. Granularity – 메트릭의 시간 간격 세분화
3. points – 리소스값 갯수를 제한하여 기록한다.

-> point 갯수 10개로 고정 1분 간격으로 metric 기록

1. sum – metric의 총 값을 계산
2. std – 표준 편차 계산 – 메트릭 값 , 날짜
3. min – 최소값 선택 You can use this aggregation method for numbers, dates, times, and durations
4. max – 최대값 선택 You can use this aggregation method for numbers, dates, times, and durations.
5. count – 선택한 특성의 값을 가진 레코드 수를 계산 모든 데이터 유형에 대해 이 집계 방법을 사용가능 이 집계는 시스템 값이 있는 레코드 수 메트릭을 구성 요소에 추가하여 적용
6. rate:mean – cpu %로 계산하기 위한 값으로 전환해주는 옵션
