Hi everybody!
We are trying the new version of vmware vRops 6.7 and there are some metric compared with the previous version that are very confuse, one of them is the "memory usage".
In vRops 6.6 the metric "memory usage" is the "guest memory", that's ok. Now you read the release notes about 6.7
"
The Memory|Usage (%) metric of Virtual Machines considers memory usage from Guest OS perspective and not from hypervisor perspective.
In previous releases, the Memory|Usage (%) metric of virtual machines referred to the amount of memory that is actively used, as estimated by VMkernel based
on recently touched memory pages.
This was different from what you would see inside the Guest OS as a memory usage.
The formula of metric Memory|Usage (%) is now changed to (Memory|Utilization (KB) / Memory|Total Capacity (KB)) * 100. Here the newly introduced Memory|Utilization (KB) metric depends on the Guest OS metric,
which is provided through VMware Tools, and is available since vCenter Server 6.0 Update 1, ESXi 6.0 Update
"
One example comparing vROPSa 6.6 and 6.7 in my enviroment
I have a VM1 with 16384 MB Ram Memory Size
VM1--> vROPS 6.6
Memory usage-->21.79 %
Memory recommendation size--> 7413 MB RAM
Active guest memory-->3768 RAM
VM1-> vROPS 6.7
Memory usage-->87.54 %
Memory recommendation size--> 16777 MB RAM
Active guest memory-->3768 RAM
will this be the topic? Because the are a lot of difference between 7,4 GB and 16 GB in recommendations terms. I have to purchase a new hardware....
Best regards
