##### SUMMARY
In my environment, I use 2 zones.

However, in the "x" zone, the metrics part presents a problem when displaying disk and network data.

While in zone "y" all data is shown normally.

Do you have any specific connectivity tests to do?

In principle, the zone settings are identical, the only difference is the following:

Zone X
System VM's -> KVM (The only KVM it has are the two SystemVM)
Zone X environment uses VMware vSphere Client version 6.7.0

Zone y uses the system VM and entire environment with vSphere Client version 7.0.3.01700

##### Remembering that the disk and network metrics just do not appear in the problem area, but the CPU and memory metrics work normally.

Zone X:

Zone Y:

El issue no menciona archivos, pruebas ni puntos de entrada. Empieza reproduciendo la metrics view en las dos zonas y comparando los entornos VMware vSphere 6.7.0 y 7.0.3.01700, centrándote en por qué faltan los datos de disco y red mientras aparecen la CPU y la memoria. Se considera terminado cuando se haya identificado y corregido la causa para que los cuatro tipos de métricas se muestren en zone X.
