In most of metrics, I see "Aggregate of all instance" metric. For example: virtual disk - " IOPS | Aggregate of all instance".
Does anybody know what is this metric? Looks like it's not sum of IOPS of all virtual disks.
Anybody know it?
@wilber8222 I had the same question and found your post through google. I think its a SUM of all the instances... from my internal investigation... but that it very unscientific. Would love to know the definitive answer. In some instances it appears to be more of an average, and others it look more like a sum of all instances. By definition of the word Aggregate... it should be the SUM of all parts.
It's when you have several sibling instances of the same metric type.
Each of the instances will be checked individually.
Useful for checking children properties like CPU(n), attached Data Stores, File Systems etc.
Hey Guys, I too am confused as to what this metric is, can we get some clarification from VMware please? I have seen scenarios where neither a sum or average equates to the aggregate metric.
I would like to now as well. somone that know?
It is strange that you dont find it on this page Virtual Machine Metrics (vmware.com)
