Hi Experts ,

Does anyone knows why some counters values are different in performance monitor and sys.dm_os_performance_counters . and how can I make them equal.
For example buffer cache hit ratio is almost 100 in performance monitor but in DMV is different . or Checkpoint pages/sec  is  0  in performance monitor and in DMV is more than 80000.

Regards

Please give us an example (screenshot).
Also confirm that you are watching for the same instances in both counters.

Ok, now I see what you are talking about.
They are on different scale. For example for Buffer cache hit ratio, in SQL Server you get the number of pages in buffer cache and in Performance Monitor you get the percentage used.
