  • This feature does not support the Goal Oriented run mode.

  • When pausing is enabled, the following features are not supported:

    • Adding Vusers

Agent limitations

The following table lists limitations for agents.

Limitation Description Limitation
Federated users LoadRunner Cloud on-premises agents (such as load generators, Git agents, streaming agents, and monitors) do not support federated users.

Monitor limitations

The following table lists limitations for monitors.

Limitation Description Limitation
Monitor types You can only add one monitor type to a test definition.
SiteScope on- premises
  • 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.
SiteScope on-premises Docker integration Standard application monitors deployed during runtime are not supported.
Dynatrace SaaS

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.

AppDynamics

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.

Application Insights

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.

Script limitations

The following table lists limitations for scripts.

Limitation Description Limitation
LoadRunner scripts Scripts created with versions prior to LoadRunner 12.0 are not supported.
LoadRunner cross Vuser transactions Not supported.
LoadRunner mobile protocols Support for Mobile Application-HTTP/HTML, TruClient Native Mobile, TruClient Mobile Web.
Web HTTP/HTML Snapshots Not supported.
WinInet Network emulation is not supported when this feature is enabled.
Maximum values
  • 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.
SAP client The SAP client must be installed before running SAP GUI scripts; SAP can then start up manually without any scripting popups.
TruClient coded scripts Not supported.
TruClient scripts

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

TruClient Script Converter Supported for Windows only.
TruClient scripts created with Firefox .xpi Not supported.
TruClient scripts created with Internet Explorer Not supported.
Localized support LoadRunner Cloud supports scripts written in non-Latin alphabets. However, you still must use Latin characters for file and folder names.
Additional Vusers Adding additional Vusers is not supported if the test uses network emulation.
64-bit Replay 64-bit Replay of LoadRunner scripts is not supported.
Script names Script names cannot contain a comma (,) or a single quote (').
Transaction names

Transaction names cannot contain a comma.

Silk Performer protocol scripts

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.

Data file limitations

The following table lists limitations for the data files.

Limitation Description Limitation
Decompressed file size

A single decompressed .zip file cannot exceed 1.2 GB. This maximum size is fixed and cannot be extended. Larger files may cause long initialization time or failure to run load tests, due to low available disk space or high CPU usage.

Zip file size

By default, a single .zip file cannot exceed 50 MB. If your .zip file is larger than 50 MB, try removing some of the non-essential and extraneous files in order to reduce the file size. Should you have good reason for uploading larger files, submit a service request and your request will be considered.

Runtime setting limitations

The following table lists limitations for runtime settings (RTS).

Limitation Description Limitation
Proxy settings

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.

Run Vusers as a process This option in a script's runtime settings is ignored and Vusers always run as threads. To request enabling Vusers to run as a process, submit a service request.

Single user performance data limitations

The following table lists limitations for single user performance data.

Limitation Description Limitation

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.

Your script is configured to run with proxy settings that are inaccessible from outside your local network

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

Disable the proxy and run the test again.

If the issue persists, submit a service request.
NV Insights report limitations
  • 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.

Report limitations

The following table lists the limitations for (new) reports.

Limitation Description Limitation
Add Notes Text formatted in italics displays as regular font in the PDF.
Custom report

You can include a maximum of 10 snapshots per report.

Raw transaction data

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.
Raw error data

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.
Load generator log files
  • 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.

Exported reports
  • Exporting data to files for LoadRunner Analysis is not supported.

  • 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.

CSV files
