KPI Graph comparison view includes comparison graphs of major performance indicators of the selected test results. It allows the quick comparison of every test run performance outcome.
To select KPI Graph Comparison View, click KPI Graphs (a) on the toolbar. Single to four-panel layouts can be selected by clicking the Layout drop-down (b).
Each graph (c) will display one of six KPI counters for every selected result.
Users curve
Starting in v6.1, each graph will also have the User curve for every selected test result. Due to this improvement, the User's graph is no longer necessary and was removed.
- Req/Sec - The number of requests being sent per second.
- Avg. Response(s) - The average response time of the sent requests. Every data point on the response time graph reflects the average value during the checkpoint intervals. If no responses were received between two data points, the response time could not be determined, so such data points are skipped to reflect an accurate response time curve.
- KB Received/Sec - The number of kilobytes currently received per second.
- Errors/Sec - The number of errors currently received per second.
- Pending Requests - The number of currently pending requests. Pending requests are issued, but StresStimulus has not yet received a response. Generally, a higher number of pending requests indicates a slower server response. This parameter can be used to gauge performance change in several test runs.
To select which graph to display in a panel, click the drop-down (d) above it.
Each graph depicts one curve for every test run. For example, if you select three test results, each graph will display three curves, as shown in the figure.
Info: Each graph supports the full range of graph and curve commands described in the Graph Commands section.
Curve grid (e) located under the graph panels, shows the following additional information about each curve.
Visible | Whether the curve is currently visible. Click the checkbox to hide/unhide the curve. |
Indicator | The name of the curve. |
Color | The curve color and point shape. |
Range | The current value range. The y-value of each point corresponds to a percent of the range. |
Min | Minimum value of the curve - datapoint aggregation (Sortable) |
Max | Maximum value of the curve - datapoint aggregation (Sortable) |
Avg | Average value of the curve - datapoint aggregation (Sortable) |
Last | The last value of the curve - datapoint aggregation (Sortable) |
| Warnings | Number of threshold violation warnings (Sortable) |
| Errors | Number of threshold violation errors (Sortable) |
| Missed Goals | Number of missed goals (Sortable) |
