    Hi,

    I want to find the lazywrites/sec.

    I read that the value should be less than 20 but when I ran below query

    select * from sys.dm_os_performance_counters

    where counter_name='Lazy writes/sec'

    cntr_value=49724 & cntr_type=272696576

    How to find value for lazywrites/sec. Is the cntr_value is the original value for lazywrites/sec or do I need to do any further calculations?

    You need further calculations (which a google search should turn up, I don't have code on hand), or instead go and look at the counters in perfmon instead.
