For what purpose does the 'Text contains' option serve in Synthetic monitoring?

The 'Text contains' option in Synthetic monitoring is used to define specific text or content that must be present in the response returned from a monitored application or webpage. This is essential for validating that the application is functioning as expected. By setting this criterion, users can ensure that specific keywords, phrases, or content appear in the response, which typically indicates that the application is not only running but also delivering the right information to users. For example, if you expect a confirmation message as part of a user workflow, using the 'Text contains' option allows you to verify that the message is indeed present, offering a reliable way to assess the health and performance of web services or applications.

Other options, such as specifying the format of the response, indicating acceptable status codes, or determining the time of the response, are focused on different aspects of monitoring and do not pertain to content validation in the same manner. The emphasis on actual content presence is crucial in ensuring that user experiences meet their expectations, validating functional correctness rather than solely monitoring performance metrics.
