Resolution: 1). What is a Collection period and how do we define it? Is it the start time of a transaction to the end time of that transaction?
A Collection period is the time frame over which statistics are collected, in rolling window format. Collection period length is the same as the length of rolling window. E.g., The default rolling window length is 5 minutes so the statistics collection period will be 5 minutes. The Start time and End time of the collection period is displayed as output of the onBindingOperationStats() method. You are able to configure a rolling window length by invoking the "changeMonitoringConfig" method of the Service Microagent.
2). What are hits?
According to product documentation, hits are the "Number of execution responses for last period".
3). What is last period?
Last period means last collection period / last rolling window period. In simple terms, the number of execution responses sent between Start time and End time of output.
4). What is Avg. Response Time?
Average Response Time is calculated using following formula:
AVGERAGE-RESPONSE-TIME = (SUM_OF_RESPONSE_TIMES) / HITS Where, SUM_OF_RESPONSE_TIMES = Sum of responce times of all the responses sent during collection period HITS = Count of the responses sent during collection period (or total number of responses sent during collection period).
