Aha, that's OK, mix also works
As you have MP v6, you will have the additional Analysis details in the Alert description - that will give you the Top 5 VMs for memory allocation on that Host.
And you also have the MP Right-Sizing Reports.
I'd suggest run the Oversized VMs report against the VMs on that Host (you can add them individually to the report scope). That will tell you if you can safely reduce the memory allocation to any of those VMs.
And if you reduce the memory allocation overall for the host, then you will reduce the memory pressure. And you'll know that your environment is right-sized
