Logins per Second is over the threshold

  • Hello.

    I got this problem in my Production Environment.

    SQL Server Instance Logins per Second is 4 Logins/Sec, where the threshold is 2 Logins/Sec.

    Where do I start to solve this problem?

    Thanks for the advice.

  • Why is 2 logins/sec the threshold and is this a problem? What's normal for this server?

    Any guidance in deciding the threshold?

    I'm quite new in administration.

  • A threshold should be above what is normal for your server.

  • Unless there's a specific reason for it, 4 logins/sec isn't freaking me out. It's just an indication of load, not a problem.

  • How can I determine the 'normal threshold' for my server?

    Count of user login?

  • The only way to determine "normal" for any system is to measure it over time.

    Monitor it for a period of time, see what the particular counter you're interested in (logins/sec in this case) has as a range. That's 'normal' for your server.
