When a ZDX custom application is configured with the type set to'Network', the administratorwill not get Disk I/O metricsfor users. Disk I/O metrics relate to local client device performance and are not part of network-type application probes which focus on network latency, server response, and other network-centric measurements.

The study guide notes that Disk I/O is part of endpoint-level monitoring and is not collected by network-type probes, unlike metrics such as Server Response Time or ZDX Score which are network related.
