Summary
- The following test(s) were included in this test session.
|LABEL |Description |Start |End | |:-------------|:-----------|:-------------------|:-------------------| |TermAppISONFT |TermAppISO |2021-06-29 11:07:00 |2021-06-29 12:28:00 |
- For test TermAppISO/TermAppISONFT (test 1, from 2021-06-29 11:07:00 to 2021-06-29 12:28:00) and for outcome timeout, the following function(s) had response time(s) in excess of 1 second during the portion of the test where the load did not exceed the current production observed/projected peak.
| |Basename |Outcome | Count| Percent| Resp| StdDev| |:--|:--------------------------------|:-------|-----:|-------:|------:|------:| |2 |transaction_advice_response_1230 |timeout | 17| 0.122| 99.999| 0|
- In the above graph, the items labelled Include and Exclude indicate, respectively, the intervals that should be included or excluded in the resource analysis. The resource analysis applies a linear regression of the resources consumed per server classification onto the total request arrival rate for that interval. Note that the analysis regresses to the arrival rate for the interval, but the determination of the outcome relates to the departures for that interval. The intervals should be long enough so that these numbers are reasonably close to each other.
- The following table shows the full set of interval summary records obtained during the test. The Interval timestamp is the start time of the interval over which the metrics are summarised for that interval. A portion of the first metric record collected for each interval may relate to the previous interval. Long intervals or many intervals at the same load make this effect negligible.
- The table of summary records provides the value of the load against which resource measurements are correlated. The correlation is determined using the least-squares linear module regressing the interval resource measurement onto the interval test loads.
- Response time (
Resp
) in the table is the mean response time that an INSTANCE (device, customer, client, etc.) takes to complete a full cycle. A cycle is the set of states/actions that an INSTANCE undergoes from awakening from the idle state to the next time the same INSTANCE awakens from the idle state). The time for a cycle includes the idle time, the sum of all the individual response times of the functions/actions performed during the cycle of activity, and the think-times between the functions/actions performed during the cycle. - The Rate column shows the rate at which the INSTANCES exit the idle state, and hence, is the customer arrival rate measure in arrivals per second.
- The summary table (or possibly a cut-down version of the summary table) is used to join against the corresponding resource usage tables, and over which the respective resource linear models are determined. The linear models include coefficients of the intercept (which is interpreted as resource usage unrelated to the applied test load) and the slope of the line (which is interpreted as the increment in the resource usage for each unit increment of the test load. This slope coefficient, therefore, gives us a measure of the resource usage for each additional customer arrival per second.

- The following table is a cut down version of the full session summary table. The rows removed from the table are those that an inspection of the performance data and the observations made during the test indicate that they should not be included in the analysis. The primary reasons for excluding a row from the analysis include where the rows cover periods where the performance profile has changed for an identifiable reason unrelated to the test load (for example, interference in the test); a period where the test conditions were not met (for example, incorrect logging levels are set); periods where the applied load has saturated a component inducing an unacceptably high error rate, changing the profile of resource usage; etc.

- The following tables show estimates and projections of CPU usage for each class (by hosted function) of server where some confidence in these numbers is reasonable. A coefficient is determined reasonable by the significance of the respective class coefficient's p-value.
- Where there is some significant response of the resource utilisation to the applied load, and where there is some confidence in this correlation, an estimate of the resource usage can be determined for capacity planning and/or comparison purposes. Here, the column
Est Use @ 30.00/s
is the expected CPU usage at 30.00 requests per second. The columnEstimate
should be used as a factor to multiply by the transaction rate in order to estimate the resource usage required to support that transaction rate. The columnStd. Error
should be used to determine the confidence interval around the estimate:

- In some cases, it is possible to estimate with confidence the background workload on the various servers and server groups, the resource usage which is independent of the applied test load. The column
Estimate
indicates this. The columnStd. Error
should be used to determine a confidence interval:

- The following tables show estimates and projections of Network usage for each class (by hosted function) of server where some confidence in these numbers is reasonable. A coefficient is determined reasonable by the significance of the respective class coefficient's p-value.
- Where there is some significant response of the resource utilisation to the applied load, and where there is some confidence in this correlation, an estimate of the resource usage can be determined for capacity planning and/or comparison purposes. Here, the column
Est Use @ 30.00/s
is the expected Network usage at 30.00 requests per second. The columnEstimate
should be used as a factor to multiply by the transaction rate in order to estimate the resource usage required to support that transaction rate. The columnStd. Error
should be used to determine the confidence interval around the estimate:

Notes from the test
Landscape
- The analysis is performed for each test within the test session and for each unique Classification of a server in the collected Server landscape/Classification list. For each Interval the resources are summed across all the servers in that class. This means that the resource usage coefficients and projections are for the total resource usage across the Classification.

Performance
- For test TermAppISO/TermAppISONFT (Test 1, from 2021-06-29 11:07:00 to 2021-06-29 12:28:00), summary of response times by operation/function-outcome over the range of loads where the arrival rate did not exceed the observed or required peak target rate of 15.00 arrivals per second (this rate is as opposed to the projected/future peak rate). This cut-off time occured at 2021-06-29 11:38:00. The descriptive statistics mean, median and sd are calculated over the entire time-frame that the arrival rate did not exceed the target arrival rate, which includes any outliers caused by possible external influences (which are removed for the regression analysis).
