遇到报错, 首先得先仔细读读人家给的出错信息. 而不是先怀疑是自己什么地方弄错了, 胡乱修改. 比如说, 遇到下面的报错:

LoadTestAgentResultsLateException    Results from agent ‘MSFT-XXXX,MSFT-XXXX‘ were not received in time to be included in the overall results for a sampling interval. To avoid this error, increase the sample rate, or decrease the load on this agent.

首先, 应该先看看你压的load是否合理, 如果合理, 那么降低sample rate.
