Statistics
Statistics graphs can be plotted in the User Paths tab.
Available statistics are:
- Average duration: Average response time
- Maximum duration: Maximum response time
- Minimum duration: Minimum response time
- Elements/s: Number of elements per second
- Throughput: Number of megabytes received from server
- Average TTFB: Average time to first byte
- Maximum TTFB: Maximum time to first byte
- Minimum TTFB: Minimum time to first byte
- Errors: Number of elements flagged as errors
- Errors/s: Number of elements flagged as errors per second
- Error rate: Number of elements flagged as errors out of the total number of executions
For Transactions only, 2 additional graphs are available:
- Duration (percentiles): allows to plot a percentile graph displaying the Transaction duration values recorded during a test.
This graph is used to determine the value of the i-th percentile of Transactions durations, where i goes from 0.1 to 0.99. This may reveal, for example, that 80% of the response times for web page P were under 5 seconds.
- Duration (scatter): allows to plot a scatter graph displaying the Transaction duration values recorded during a test.
This may reveal, for example, that the specific period when a given Transaction duration was above a given limit was mostly during the first hour of the test.
about scatter graphs:
They can only be drawn on an empty panel or over another scatter graph.
The number of points for the whole duration of the test is fixed at 3600 for x axis and 1800 for y axis. These values are configurable in the scatter.domain.resolution and scatter.range.resolution properties of the controller.properties file.
