The Service Performance report summarizes the validity
of the run, summarizes the data most significant to the run, shows
the response trend of the slowest 10 service calls in the test, the
server health depending on requests, and graphs the response trend
of each service calls for a specified interval.
Overall page
The Overall page provides the
following information:
- A progress indicator that shows the state of the run.
- The first bar graph indicates the percentage of successful
service calls during the run.
- The second bar graph indicates the percentage of verification
points with a Pass status for the run.
Summary page
The Summary page summarizes the
most important data about the test run, so that you can analyze the
final or intermediate results of a test at a glance.
The Run Summary
table displays the following information:
- The number of virtual users that are active and the number of
virtual users that have completed testing. These numbers are updated
during the run.
- The elapsed time. This is the total duration of the run, which
is displayed in hours, minutes, and seconds.
- The location and name of the test.
- The results for the computer and for all computers. To see summary
results for individual computers, click the computer name in the Performance Test Runs view.
- The status of the run. This can be Initializing Computers, Adding
Users, Running, Performing Execution History Data Transfer, Stopped,
or Complete.
- The total number of virtual users emulated during the test.
The Call Summary section displays the following information:
- The percentage of verification points with a Pass status.
- The total number of verification points with a Fail status.
- The total number of verification points with an Error status.
- The total number of attempted service calls.
- The total number of successful service calls.
- The total number of service calls that produced a timeout.
The Bytes Summary section displays the following information:
- The minimum, maximum, and average number of bytes sent and received
for each call in the run.
- The byte rate per second for the run.
- The total number of bytes sent and received for the run.
Response Time Results page
The Response Time
Results page shows the average response of the service calls in the
test as the test progresses. With this information, you can evaluate
system response during and after the test. The delay between the moment
a service call is invoked and the moment the corresponding message
return is received, determines the
Response times.
The bar chart shows the average response time of each service call.
Each bar represents a service call that was invoked during the test.
As you run the test, the bar chart changes, because the response times
are updated dynamically during the run.
The table that follows
the bar chart provides the following additional information for each
service call:
- The minimum response time during the run.
- The average response time during the run. This matches the information
in the chart.
- The maximum response time during the run.
- The standard deviation response time during the run.
Response Time vs. Time Summary page
The
Response vs. Time Summary page shows the average response trend as
graphed for a specified interval. You set the Statistics
sample interval value in the schedule, as a schedule property.
Measurements that are located in the tests determine the Response
times. Response time measurements can be automatically generated
between the last input action before a service call and the corresponding
message return event.
The line graph shows the average response
time for all measurements during the run. Each point on the graph
is an average of what has occurred during that interval. The table
that follows the graph lists one number: the total average response
time for all measurements in the run.
Response Time vs. Time Details page
The
Response vs. Time Details page shows the response trend as graphed
for a specified interval. You set the Statistics sample
interval value in the schedule, as a schedule property.
The delay between the moment a service call is invoked and the moment
the corresponding message return is received determines the Response times.
The line graph shows the average response
time of each measurement for a specified interval. A separate line
represents each measurement.
The table under the graph provides
the following additional information for each response time measurement:
- The minimum response time during the run.
- The average service call response time during the run. This is
similar to the graph, but the information in the table includes the
entire run.
- The maximum service call response time during the run.
- The standard deviation service call response time during the run.
Data Volume page
The Data Volume page provides
details about the volume of data that is sent to and received from
the service. You set the
Statistics sample interval value in the schedule, as a schedule property.
- The Sent and Received line graph shows
the total bytes sent and received per interval.
- The Received Summary table lists, for each
call, the received volume rate (bytes per second) for the entire run,
the minimum and maximum received bytes per interval, and the average
number of bytes received for each call.
- The Sent Summary table table lists, for
each call, the sent volume rate (bytes per second) for the entire
run, the minimum and maximum sent bytes per interval, and the average
number of bytes sent for each call.
Call Throughput page
The Call Throughput
page provides an overview of the frequency of service calls that are
being transferred per interval. You set the
Statistics
sample interval value in the schedule, as a schedule property.
- The line graph shows the calls that are started and ended per
interval. Ended calls can be: success, fail, or timeout.
- The Performance Summary table table lists
the details of the number of call starts, successes, failures or timeouts
for each call and for the run.
Resources page
The Resources page shows all
resource counters that are monitored during the schedule run.
