During a routine check, an administrator observes that several VMs are reporting high memory usage in VMware Aria Operations. They need to verify if the high memory usage is due to memory contention. What actions should be taken in VMware Aria Operations to verify this?

To verify if high memory usage is due to memory contention, the administrator should check the memory usage and ballooning metrics in VMware Aria Operations. Ballooning occurs when the hypervisor reclaims memory from a virtual machine due to memory contention, and monitoring these metrics can help identify whether the VMs are experiencing memory pressure or being forced to swap memory.
