Priority based throttling testing

(0) ShareShare

Posted on by 10

Hi all,,

I have a question regarding the priority based throttling: https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/data-entities/priority-based-throttling

Is there a way to actually enforce a throttling scenario in a D365 machine  so it can be tested (I`m using an Azure hosted VM with PU37)?  

I have an external application that`s programmed to handle the 429 HTTP status code that should be returned by the D365 server in this scenario, so i`m trying to find a way to actually overload the server so I can test my external app`s code.

i`ve tried changing the throttling related properties in the WebCofig file to some very low numbers in order for the server gets easily overloaded, but without success:

<add key="Aos.ThrottledSchedulerMemoryReservationLimit" value="10" />

<add key="Aos.ThrottledSchedulerSqlCpuReservationLimit" value="10" />

 Also I`ve tried to configure the IIS CPU throttling setting, by setting a 1% limit, but this eventually made the response very slow but never returned a 429 status.

https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-8/iis-80-cpu-throttling-sand-boxing-sites-and-applications  

Any other ideas how to achieve this?

    I got an answer on the MS 'Finance and Operations Insider Program' yammer group:

    https://www.yammer.com/dynamicsaxfeedbackprograms/#/threads/show?threadId=863798655729664

    This feature is not supported for the cloud hosted one box environments yet (only telemetrics are provided), so we can`t have a real life test scenario.

    The best we can do at this point is simply to call a dummy api that returns a 429 HTTP status. (example Fake JSON API | Mocki).

    So if anyone wants to test his code before the official feature launch in April this year this way is an alternative.
