Load and performance testing threshold violations

    Question

  • hi,

    i have been getting threshold violations while running load test at first it were just minimum like 12 but later kept on increasing till 36 but all were under threshold value 100.

    All of them related to memory(80%) and idle disk(20%).

    Please help me in solving this errors.

  • Hi Shobha59,

    Could you share us the errors about the threshold violations in your load test result?

    If possible, please have a look at this article to understand the threshold violations and the default threshold rules http://msdn.microsoft.com/en-us/library/ms404694(v=vs.80).aspx

    For example:

    There are two types of thresholds: warning and critical. A message notifies you if the threshold rule is violated. If the value in your load tests results is higher than the default value of warning and critical in some Counters, you will get Threshold violations. You can view threshold violations when you analyze a load test run.

    Like the following document/thread I met before:

    https://social.msdn.microsoft.com/Forums/en-US/f04fa311-0ddb-4697-853e-be1bcb5d24a7/threshold-violations

    Generally if the value is more than the default value, generally it means that it met a bottleneck like this document:

    https://ecanarys.wordpress.com/2012/08/24/troubleshooting-load-test-threshold-violations/

    So one idea is that you could improve your server machine's performance/configurations, or use the more reasonable load test parameters like few v-users or others.
