During the test run, you can add widgets from the gallery to the dashboard to display real-time data detailing the results of your load test. This topic describes LoadRunner Cloud's former dashboard. For the new enhanced dashboard, see Dashboard.
You can also access the results after the test has completed.
Note: Before you run your load test, check that your monitor or monitoring tool is up and running and that LoadRunner Cloud is connected to it. For details, see Monitors.
Where do I find it?
Navigate to the Load Tests page, select a test, and navigate to the Runs tab.
Navigate to the Results page.
For a selected test run, click (more options) and select Dashboard.
Switch off the New Dashboard & Report toggle .
Add a custom snapshot of a dashboard widget to the report
You can save a snapshot of a widget for a specific filter, split, and time period and display it in the report for the run.
To add a snapshot:
- Navigate to Results > Dashboard for a specific run.
- Zoom to a specific time frame in the test run.
- Configure what data is displayed in a widget.
- Click in the widget header to save the snapshot.
For details on viewing and configuring snapshots, see Preview the snapshot in the report.
You can configure a load test to enable you to pause the schedule while the test is running. This gives you more control over the test's workload.
You can pause the scheduling multiple times during a test run, but the total pause time cannot exceed the maximum time that you set in the General settings. To enable schedule pausing, select the load test's General settings > Pause scheduling up to check box. For details, see Pause scheduling.
- To pause scheduling when viewing an active test run in the dashboard, click the Pause scheduling button on the toolbar. A counter displays the available time that the schedule can been paused during the run.
- To resume, click .
In the test run's report, the Pause Scheduling table displays the pause and resume instances that occurred during the run. For details, see Report.
You can dynamically increase or decrease the number of running Vusers during the test run. In order to modify the number of running Vusers, make sure you have the Add Vusers option selected in the test's General settings. For details, see Add Vusers.
To change the number of running Vusers during a test run:
- Click to open the Change Load dialog box.
For any script displayed, changed the number of current users to the new number you want. You cannot exceed the maximum number of users displayed.
Example: For any of the scripts listed you can enter any number between 0-20.
When you remove Vusers, you are actually suspending them. If you later decide to add more Vusers, the suspended Vusers are added first.
If the script was created using VuGen, enable the Simulate a new user on each iteration option (Runtime Settings > Browser Emulation) to allow you to resume suspended Vusers during a test run.
Suspended Vusers will run a vuser_end() action at the conclusion of the test. This may cause unexpected behavior in the test results.
Note: You cannot change the load for scripts that contain rendezvous points.
Evaluate a test's status
During a test run, the test summary contains gauges displaying the current value of the following metrics:
The total number of Vusers either running in the test or in the initialization stage.
|Suspended Vusers||The number of Vusers that have been suspended during the test with the Change load feature.|
|Throughput||The amount of data received from the server every second.|
|Transactions per second||The number of transactions completed per second.|
|Hits Per Second||The number of hits (HTTP requests) to the Web server per second.|
|Failed Vusers||The number of Vusers that have stopped running or have stopped reporting measurements due to server or script error.|
|Failed Transactions||The number of transactions that did not successfully complete.|
|Successful transactions||The number of transactions that have completed successfully.|
|Errors||The number of script errors.|
After a test run, the test summary contains general information about what happened during the test:
|Date & Time||
Date and time the test ended.
The duration of a test, including ramp up and tear down.
|API Vusers||A Vuser emulates a user's actions at the network API level. For example, HTTP requests and responses without rendering the UI.|
|UI Vusers||A virtual user that emulates a user's actions on the UI level. For example, a button click. Since the UI is rendered for each Vuser, these Vusers consume significantly more processing resources.|
Toggle between the various analytics:
The status of the test.
Note: If you selected General Settings > Group Transactions when you configured the load test, SLAs are calculated on the transaction groups and not on individual transactions. This means that a test can have a status of Passed, even though an individual transaction may have failed.
The notification area alerts you to the problems that were found during the test run in the following categories:
Lists transactions that broke the defined SLA threshold.
Indicates an SLA warning has occurred.
Indicates an SLA warning has been detected. Drill down on geographies to view it.
Measurements that significantly changed their behavior.
Indicates an anomaly has occurred.
Indicates an anomaly has been detected. Drill down on geographies and scripts to view it.
What does it tell me about my test?
Each measurement is listed by rank, illustrating the likelihood that it caused the anomaly.
The likelihood that a measurement caused the anomaly is determined by three criteria:
Shows the number of errors encountered while running the scripts in the test. Click the number, to display a list of the errors.
From the list, you can:
Lists scripts, for each load generator, that had any of the following problems:
To add this information as a widget on the dashboard, click .
Lists warnings about the number of script errors encountered during a load test that could not be sent to Splunk.
Note: This tab is displayed only for load tests that have been configured to stream script errors to Splunk.
From the Results page, the feature enables you to group your load tests by the following columns:
- Test name
- Triggered by
You can also use the date picker to specify a date range to display load tests run for that period.
Change how time is displayed in your results
You can view results in test or clock time.
When you change the time format, all measurements, including SLA warnings and anomalies, are displayed in the selected format.
- Test time. Time is displayed according to the duration of the test. For example, if you run a test for 20 minutes, 10:00 refers to ten minutes into the test run.
- Clock time. Time is displayed according to the server time during the test run. For example, 10:00 refers to 10:00 a.m.
