What is necessary for creating custom applications in ZDX?

To create custom applications in Zscaler Digital Experience (ZDX), it is necessary to create at least one web probe. Web probes are essential as they monitor the performance of the defined applications by sending requests to them and capturing metrics such as response times and availability. This data is crucial for assessing the user experience and identifying potential issues with the application performance.

Without a web probe, the custom application cannot be monitored effectively, limiting the ability to gather insights needed for improvement and troubleshooting. This makes the requirement of at least one web probe a fundamental aspect of establishing custom applications in ZDX.

In contrast, having a minimum of two web probes is not a requirement and could be unnecessarily complex for the initial setup. Additionally, stating that there are no requirements for web probes neglects the need for performance monitoring. Claiming that custom applications cannot be created at all is incorrect as ZDX explicitly allows for the creation and monitoring of custom applications, given the establishment of the necessary probes.
