measuring concurrent users

  • Hi all

    I would like to get peoples thoughts on how they currently measure concurrent database users. Do you:

    a) consider each SPID a concurrent user?

    b) only "active" or running SPIDS (partaking in a user transaction)?

    c) use the "transactions/sec" counter average?

    d) avg logins per sec perf counter?

    e) avg num of user connections perf counter?

    f) active transactions perf counter?

    Cheers

  • When considering concurrent users of a database I go with number of SPIDS as this is the number of connections open to the database at the time. However if you are talking about concurrent transactions "transactions/sec" counter average is a good way to get the best average but this is server wide which may be what you were after anyway.

  • I go with spids too. Its not 100% of course, but for my purposes doesnt matter. Even that is a swag depending on how the apps are managing their connections.
