Buffer Cache Washes

This section reports:

A buffer is considered “dirty” when the data page it represents in a data cache includes changes that Adaptive Server has not written to disk. A buffer is considered “clean” when the data page it represents it is a copy of the data on disk.

The number of dirty buffers includes those already in I/O due to writes being started at the wash marker.

The “Recovery Management” section of sp_sysmon reports how many times the housekeeper wash task was able to write all dirty buffers for a database. See“Recovery Management”.
