| CpSyncedPages | The number of fsynced pages in the current checkpoint.
| CpWriteSpeed | The checkpoint write speed, in pages per second. The value is
averaged over the last 3 checkpoints plus the current one.
| CurrDirtyRatio | The current ratio of dirty pages (dirty vs total),
expressed as a fraction. The fraction is computed for each segment in the
current region, and the highest value becomes "current."
+| DirtyPages | Current number of dirty pages in memory.
| LastEstimatedSpeedForMarkAll | The last estimated speed of marking all clean
pages dirty to the end of a checkpoint, in pages per second.
+| LoadedPages | Current number of pages loaded in memory.
| MaxSize | The maximum in-memory region size in bytes.
| MarkDirtySpeed | The speed of marking pages dirty, in pages per second. The
value is averaged over the last 3 fragments, 0.25 sec each, plus the current
fragment, 0–0.25 sec (0.75–1.0 sec total).
+| PageReplacements | Number of times a page was replaced (evicted) from the
page cache.
+| PageCacheHits | Number of times a page was found in the page cache.
+| PageCacheMisses | Number of times a page was not found in the page cache and
had to be loaded from disk.
+| PageCacheHitRate | Page cache hit rate over the last 5 minutes.
+| PageAcquireTime | Distribution of page acquisition time in nanoseconds.
| SpeedBasedThrottlingPercentage | The fraction of throttling time within
average marking time (e.g., "quarter" = 0.25).
| TargetDirtyRatio | The ratio of dirty pages (dirty vs total), expressed as a
fraction. Throttling starts when this ratio is reached.
| ThrottleParkTime | The park (sleep) time for the write operation, in
nanoseconds. The value is averaged over the last 3 fragments, 0.25 sec each,
plus the current fragment, 0–0.25 sec (0.75–1.0 sec total). It defines park
periods for either the checkpoint buffer protection or the clean page pool
protection.
