Hello all:
I am a little confused with the output of sys.dm_os_performance_counters DMV.
For example, when it comes to the Buffer cache hit ratio, I am used to seeing a value expressed as a percentage. The cntr_value in the DMV is a bigint value.
If the cntr_value for the Buffer cache hit ratio is "7003" should I interpret that to mean that the Buffer cache hit ratio is 70.03%?
Here is sample of the output for your reference:
object_name counter_name instance_name cntr_value cntr_type
SQLServer:Buffer Manager Buffer cache hit ratio 7003 537003264
