Siemens U3585-J-Z125-8-76 1, SM2 monitoring system manual DAB report, Write 1/S

SM2 reports	DAB report
RD HIT (%)	Percentage of read operations without disk access.
	SM2 compares the number of read operations for which disk access
	was not required (as the data to be read was already in the cache)
	with the total number of read operations in all subareas or files
	served by the DAB cache.
WRITE (1/S)	Number of write operations per second to all subareas or files
	served by the DAB cache
WR HIT (%)	Percentage of write operations in which data was written to the
	cache in relation to the total number of write operations to all
	subareas or files served by the DAB cache
OVER (1/S)	Number of failed attempts to use the DAB cache per second due to
	an overload

Note

While the SM2 DAB report contains the data of the last monitoring cycle, the BS2000 command /SHOW-DAB-CACHING supplies the READ, WRITE and HIT values since the DAB buffer was set up. The values of the DAB report and those of the SHOW-DAB- CACHING command cannot therefore be compared directly.
