JVM의 "가비지 컬렉션" 로그 형식은 다음과 같습니다:
1. 각 줄은 타임스탬프에서 시작하는 단일 가비지 수집 작업을 나타냅니다.
2. JVM에서 서로 다른 메모리 영역의 이전과 이후 크기는 "MemoryArea : BeforeSize->AfterSize(AllocatedSize)"로 표시되며, 여기서 MemoryArea는 PSYoungGen, ParOldGen 또는 Metaspace 중 하나입니다.
3. "MemoryArea:"가 생략된 경우, 전체 JVM 메모리의 이전과 이후 크기를 나타냅니다.
4. 각 줄에는 연산에 걸린 시간(초)이 표시됩니다.

다음 로그를 요약하고 중요한 이상 징후를 기록합니다:

1. 로그에는 2023년 3월 30일 오전 7시부터 오전 7시 36분까지 36분 간격으로 47개의 GC 작업이 기록되어 있습니다(UTC 기준).
2. GC 작업은 대략 1분에 한 번씩 시작하여 각각 5초 미만이 걸리지만 오전 7시 23분 이후에는 갑자기 각각 약 30초가 걸리며 1분에 두 번 발생합니다. 즉, 처음에는 GC 작업이 JVM 시간의 일부를 차지하지만 나중에는 거의 모든 시간을 차지합니다.
3. 이 두 번째 주기의 GC 작업으로 인해 전체 메모리 크기와 PSYoungGen, ParOldGen 및 메타스페이스 메모리 영역이 매우 약간 감소합니다. 이 동작은 오전 7시 26분 51초 이후에 특히 심합니다.
4. 이는 GC 작업에 많은 시간이 소요되었지만 결과는 거의 없었음을 나타냅니다.
5. 총 메모리 크기는 처음에 49.5GB에서 52.3GB로 천천히 증가하지만 두 번째 기간에는 약 78GB로 최대가 됩니다.
6. 할당된 메모리 크기는 GC 작업의 두 번째 주기 동안 82GB로 고정되어 외부 한계를 나타냅니다.
7. 할당된 최대 메모리를 82GB 제한 이상으로 늘리고 가능하면 두 배로 늘린 후 JVM을 다시 실행하는 것이 좋습니다.
The "Garbage collection" log of a JVM is formatted as follows:
1. Each line represents a single garbage collection operation starting at the timestamp. 
2. The before and after sizes of different memory areas in the JVM are shown as  "MemoryArea : BeforeSize->AfterSize(AllocatedSize)" where MemoryArea is one of PSYoungGen, ParOldGen, or Metaspace. 
3. If the "MemoryArea:" is omitted, it represents the before and after size of the entire JVM's memory. 
4. Each line has the time taken for the operation in seconds.

1. The log has 47 GC operations over a 36-minute interval from 7:00 AM to 7:36 AM on 30th March 2023 UTC. 
2. The GC operations start at roughly one per minute and take less than five seconds each, but after 7:23 AM, they abruptly take about 30 seconds each and occur twice a minute. In other words, initially, GC operations take up a small fraction of the JVM time, while later, they take up almost all of its time.
3. GC operations in this second period result in a very slight decrease in the total memory size and the PSYoungGen, ParOldGen, and Metaspace memory areas. This behavior is especially acute after 7:26:51 AM.
4. This indicates much time spent in GC operations with little result.
5. The total memory size initially slowly grows from 49.5GB to 52.3 GB, but in the second period maxes out at around 78 GB. 
6. The allocated memory size is fixed at 82 GB during the second period of GC operations, indicating an outer limit.
7. I recommend increasing the maximum allocated memory beyond the 82 GB limit, doubling it if possible, and re-running the JVM.
