This metric provides a distribution of . Distribution buckets and ranges are configurable. For more information, see .
Percentile metrics provide a means to quantify the quality of service customers are receiving based on the response time that a fixed percentage (usually 95 percent) of users receive. These metrics are commonly referred to as 95th Percentile metrics. The exact percentage the system uses is configurable by the user.
This metric provides a numeric value that represents the upper level of achieved by the desired percentage of events.
To calculate this metric, the system uses a statistical method involving standard deviation rather than tracking each individual event in memory (that approach would be prohibitive in terms of processing requirements and memory consumption).
This metric illustrates the amount of overhead that is present in messages generated by servers providing a Web service. It can be helpful in determining whether an operation should be optimized because it is requiring too much overhead.
The first part of the calculation determines the size in bytes of the SOAP overhead in the SOAP response. This can be calculated by subtracting the HTTP header size and the size of the SOAP body from the size of the entire HTTP response. What remains is the size of the SOAP overhead portion of the response in bytes
