Das "Garbage collection"-Protokoll einer JVM ist wie folgt formatiert:
1. Jede Zeile steht für einen einzelnen Garbage Collection-Vorgang, der mit dem Zeitstempel beginnt.
2. Die Vorher- und Nachher-Größen der verschiedenen Speicherbereiche in der JVM werden als "MemoryArea : BeforeSize->AfterSize(AllocatedSize)" angezeigt, wobei MemoryArea eines von PSYoungGen, ParOldGen oder Metaspace ist.
3. Wenn "MemoryArea:" weggelassen wird, steht es für die Vorher- und Nachher-Größe des gesamten Speichers der JVM.
4. Jede Zeile enthält die für den Vorgang benötigte Zeit in Sekunden.

Fasse das folgende Protokoll zusammen und notiere alle wichtigen Anomalien:

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. 

Summarize the following log and note any significant anomalies:

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.
1. Das Protokoll enthält 47 GC-Vorgänge in einem 36-Minuten-Intervall von 7:00 Uhr bis 7:36 Uhr am 30. März 2023 UTC.
2. Die GC-Operationen beginnen mit etwa einer pro Minute und dauern jeweils weniger als fünf Sekunden, aber nach 7:23 Uhr dauern sie plötzlich etwa 30 Sekunden und treten zweimal pro Minute auf. Mit anderen Worten: Zu Beginn nehmen die GC-Vorgänge nur einen kleinen Teil der JVM-Zeit in Anspruch, später jedoch fast die gesamte Zeit.
3. Die GC-Operationen in dieser zweiten Periode führen zu einer sehr geringen Verringerung der gesamten Speichergröße und der Speicherbereiche PSYoungGen, ParOldGen und Metaspace. Dieses Verhalten ist nach 7:26:51 Uhr besonders ausgeprägt.
4. Dies deutet darauf hin, dass viel Zeit mit GC-Operationen verbracht wurde, ohne dass etwas dabei herauskam.
5. Die Gesamtspeichergröße wächst zunächst langsam von 49,5 GB auf 52,3 GB, erreicht aber im zweiten Zeitraum einen Höchststand von etwa 78 GB.
6. Die Größe des zugewiesenen Speichers ist während der zweiten Periode der GC-Operationen auf 82 GB festgelegt, was auf eine äußere Grenze hindeutet.
7. Ich empfehle, den maximal zugewiesenen Speicher über das Limit von 82 GB hinaus zu erhöhen, wenn möglich zu verdoppeln, und die JVM neu zu starten.
