Errors tab

The Errors tab provides error information at the aggregate and test level.

At each level, the Performance dashboard groups errors into categories. See the next section, Error Categories, for more information.

An analysis of errors is also shown in the Analysis tab.

Error categories

The Performance dashboard groups errors into these categories:

HTTP

The test had a HTTP 4xx (client error) or 5xx (server error) response status code.

Refer to the World Wide Web Consortium website for more information about HTTP response codes.

Network

The test returned an error code excluding these codes:

  • 15001 – User Script Processing Failed
  • 30500 – Text Match Failed
  • 31000 – Timeout Exceeded

Timeout

The test returned an error code 31000 – Timeout Exceeded.

The transaction failed because the end-to-end response time of the transaction exceeded the current limits. The default timeout limits are 2 minutes per page and 5 minutes per transaction.

User script

The test returned an error code 15001 – User Script Processing Failed.

The required elements for the next user script action were not available on the page. This is typically a CSS locator.

Content match

The test returned an error code 30500 Text Match Failed.

The content match condition defined for this page or object was not met. This is usually due to the appearance of an error page or a site change.

Viewing aggregate information

In the aggregate view, the Errors tab lists the total number of errors for all tests in this dashboard by category.
