  Hi everybody , I need your help please :

  I want to create a graph to show the progression of the "buffer cache hit ratio" for last 7 days (a week).

  Until now I use this script (actual moment ) :

  SELECT CAST(

  (

  SELECT CAST (cntr_value AS BIGINT)

  FROM sys.dm_os_performance_counters

  WHERE counter_name = 'Buffer cache hit ratio'

  )* 100.00

  /

  (

  SELECT CAST (cntr_value AS BIGINT)

  FROM sys.dm_os_performance_counters

  WHERE counter_name = 'Buffer cache hit ratio base'

  ) AS NUMERIC(6,3)

  )
