Any test that exceeds the threshold for the following elements is stopped and assigned a Halted status:

• More than 10,000 unique transaction names

• More than 4,000 unique user data points

• More than 4,000 errors

To continue, try modifying your script.

• If you select or clear the Disable integration check box in the SiteScope configuration, but the agent continues to behave as it did before you made the change, restart the SiteScope service.
• If a monitor that you did not select appears in the monitor gallery, stop the load test, and reset the SiteScope agent and the SiteScope service.

For Dynatrace SaaS monitors, metrics are shown with a delay of approximately two minutes. This means that a load test that runs for less than three minutes may not display any metrics.

• The script size cannot exceed 200 MB.
• The maximum number of scripts that can be added to a load test is 100 for trial versions and 500 for non-trial versions.
• The maximum number of scripts that can be uploaded to a tenant is 500 for the trial versions and 30,000 for non-trial versions.

Script is stopped if it hangs for more than 10 minutes.

Transaction names cannot contain a comma.

The following limitations apply:

• Only Log runtime settings are supported. For details, see Runtime settings.
• The Copy runtime settings capability is not supported.
• Think time is always reported in the transaction response time as 0.
• NV (Network Virtualization) is not supported.
• Goal oriented scenarios are not supported.
• Synchronization functions, such as rendezvous points and GlobalWaitFor, are not supported.

• For the Silk Web browser-driven (SP Browser-driven) protocol:

  • To see the open browser-driven load test browsers, implement the test on a script level.
  • If the Load Generator is running as a service, the browser opens in another session in Windows. To see the browser, open it in an interactive RDP session. For details, see Run Vusers in an interactive RDP session.

If your script is configured to run with proxy settings that are inaccessible from outside your local network, LoadRunner Cloud may ignore RTS settings. Disable the proxy settings and run the test again.

If the issue persists, submit a service request.

Number of scripts

• NV Insights report. You can specify one script per test.
• TRT breakdown. You can specify up to five scripts per test.

Script type

Only Web HTTP/HTML, TruClient Mobile Web, TruClient Chrome, and TruClient Firefox scripts are supported.

TRT breakdown widgets and the NV Insights report are not generated.

Disable the proxy and run the test again.

• The network scenario is displayed as default scenario.
• Total throughput per transaction is not supported.
• The NV Insights report does not support scripts in which WinInet is enabled.

• Generating a WebPage Test report adds additional time (10 to 20 minutes after the last running Vuser is stopped) to your test run.

You can include a maximum of 10 snapshots per report.

When you export raw transaction data to a .csv file, the following limitations apply:

• Only transactions that passed are included.
• Transaction groups are not included.
• A maximum of 100 million entries can be stored.
• The data is retained for one week, after which it is automatically purged.

When you export raw error data to a .csv file, the following limitations apply:

• The report includes a column for transaction ID. This column is populated only for MDRV (VuGen) script protocols.
• A maximum of 500,000 entries can be stored.

• A log file is generated for each Vuser in a test run.

• The total size of all the log files included in an export cannot exceed 15 GB.

• For an on-premises load generator, the size of all the Vuser log files together cannot exceed 512 MB. For a cloud-based load generator, the maximum size is 1 GB. If these maximum values are exceeded, some of the log files for that load generator may not be included in the exported logs for a test run.

• A long test run with a large number of Vusers and unique transactions increases the amount of data, so that some of the Vusers may exceed the maximum log size.

The maximum number of metrics that can be exported to a report is 4,000.

Note: This limitation may be subject to changes in future releases of LoadRunner Cloud.

The maximum number of rows that can be exported to a CSV file is 750,000.

• The maximum number of tabs that you can open is 20.

• The maximum number of different metrics that can be displayed per tab is 1000.
