SQL PI

Am I correct in assuming that the chart scale in SQL PI (seconds/s) is seconds per session?

  • Hi, 

    The seonds/s metric is seconds per second. It represents the number of seconds of db workload (cpu usage + wait time) per second (time).

    If you had a single CPU instance you would have 3600 seconds of compute available each hour. If you had queries using all of the CPU, it would average 1 second/s

    If additional SQL starts waiting on cpu or other resource, that graph starts to climb.

    In multi-core servers, you will have "core count" x 3600 seconds available each hour for CPU.

    There's also a support KB available here with additional explanations.
