Errors

This tab contains details of the HTTP request errors.

• Warning: For more information about various topics affecting this subject, such as Filter by Zone, Population or Virtual User, see General information about test results.

General information

The number of errors displayed varies depending on the zone, Population and Virtual User selected during filtering. If the "Storage capacity exceeded" warning message displays, it indicates that the actual number of errors recorded during the test exceeds the number of errors displayed. By default, the maximum number of error details stored is 20,000.

Increasing the maximum number of stored errors will have an impact on NeoLoad performance.

• To change the error detail storage capacity limit

1. Stop NeoLoad.
2. Open the <install-dir>/conf/Controller.properties file in a text editor.
3. In the [Results]category, change the value of the max.errors.store.count key. The default value is 20000.
4. Re-start NeoLoad and repeat the load test.
