User's load

Posted on by Morten Jes Lehrmann 700

What are the possibilities of measuring single user's load, e.g. CPU and disk usage, executed batch'es etc. in Dynamics AX2009 and 3.0. I can see that "Online time" per standard is logged but this is not enough for our purpose.

 Any 3.party solution maybe? Or possibly simple solutions?

Kind regards,

    It's a treaky question because a "user load" can be considered as:
    • DBMS load (in case of "heavy" queries) related to a DBMS working process used by the user session
    • AOS CPU load related to the AOS thread that runs the user's session server application code (AOS starts a separate thread per user session)
    • AOS memory load related to the [AOS thread that runs the] user's session
    • Client CPU load (should be considered in case you run DAX clients on a Terminal Server)
    • Client memory load (also related to a Terminal Server if any)
    • Network bandwidth consumed by a client-server communication
    AOS CPU load is one of the simpliest to determine. There's an article Which user loads AOS' CPU? (in Russian) that explains one of the solutions. The idea is based on the fact that AOS starts a separate thread for each user session so you can start Microsoft QuickSlice utility (or any other process monitor that shows per-thread process CPU load), find out which thread loads CPU most and note it's thread id, then go to Windows Application Event Log and look for a recent AOS event logged upon a session start where that thread id is mentioned. The event will also contain the DAX user id. Another solution is to use a customization for the Users Online form (you have to register on the forum to download the attachment).

    Very interesting suggesions. However, they may be hard to use to solve my issue because I need an automatic gathering of data for a monthly internal recharge of cost of our AX installation based on user's load on the system.

    Well then... you can customize your application to log some statistics automatically, f.e. start stats collection in Info.startupPost() (see The order of events when you start) and periodically dump them in Info.watchDog(). But note that AX3.0 doesn't support impersonation for batch jobs so you'll also have to customize RunBaseBatch class to log stats for batch job submitted by users (see createdByUserId variable).
