Reading the output of sys.dm_os_performance_counters

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
