@jayakarteek from what I understood so far, there will always be a mismatch.
For instance, the way it is implemented so far, if a VM uses a service
offering that provides 1000 MHz; and if CPU cap is not used, it (the VM) can
use up to the real CPU of the host. If real CPU on the host is 2000 MHz, then
it would show 200% of usage. Unless we want this behavior, the use of
CPUCounter seems a better approach to avoid having an inconsistent POJO in the
code. You said it might not be ideal because the CPUCounter (per its
documentation) does not seem to consider the amount of virtual CPU allocated in
MHz while calculating usage, right?
I just started this discussion because of the POJO that has an attribute
that sometimes is set using percentage values and some other as continuous
values. My goal was to highlight this and maybe discuss some solution.
I was reading the documentation link you sent, what are the differences
between âcpuentitlementâ and âreservedCapacityâ; I mean, I can read the
description of the parameters
> cpuentitlement is computed based on an ideal scenario in which all
virtual machines are completely busy and the load is perfectly balanced across
all hosts
but the description for me seems different from what I can understand from
"entitlement" when I read "CPU entitlement" I think of CPU power that the CPU
is entitled and may not be using or getting for one or other reason. However,
the description may sound like something else (this value being based on the
load of hosts/clusters).
Would not one of these two configurations have the CPU in MHz allocated
for the VM?
