Thanks for the quick respons, but there is no memcached running on that VM.

Do you have memcached running in this vm?
I heard about this issue with memcached, but never tested memcached in
my oVirt environment. You get the real usage value with
memory.used = memory.installed + memory.used

Guys,
these values are usually a result of overcommitment mechanism usage.
For example, if KSM is effective, it will free a lot of memory pages,
and total-free-committed becomes negative.
This was reported in https://bugzilla.redhat.com/show_bug.cgi?id=977758
and the engine is using memFree reported by vdsm, which is more accurate.
The API reports the old version due to backwards compatibility.

Thanks a lot for the information.

and the engine is using memFree reported by vdsm, which is more accurate.
The API reports the old version due to backwards compatibility.
I just had a look at the bugzilla report and the RHEV documentation
which says "Current memory in bytes used by the virtual machine.".
So this means, the reported values are totally useless for monitoring
memory usage of a virtual machine if KSM is active. I would expect to
get the memory usage of a virtual machine and not how much memory is
consumed on the hypervisor (this is pretty useless information for me).
Is it planned to report the memory usage in a virtual machine in the API
as well?

Hi,
I'm interested in the very same question.
Additionally I don't see any way how this would
break backwards compatibility.
In contrary, in 3.4 some other values in the API change
in a not backward compatible way, which actually do what they
are supposed to do, so even if it would break compatibility
this wouldn't clearly be a "no go" as it is done in other parts
of the API too.
In case you don't know which values I mean:
I talk about the JSON implementation.
I think the old value is pretty useless and needs to be fixed.
So I don't see how a fix to this value should break any compatibility.
I would be very interested in seeing the actual code which relies on
negative values of consumed ram inside a vm. What would you do with it?

hello rene
it's during testing check_rhev3 that we found this issue
do you see a workaround for this?
At the moment I can only set the memory usage to 0 and add comments to
the documentation that vm memory usage is the usage of the vm on the
host, but not the memory usage in the vm (which I thought it was).
This issue was reported once to me, and check_rhev3 has a calculation of
the memory usage if it's negative in version 1.3, but this only solved
the issue accidentally for this specific vm of this user. As Doron
explained me in previous mail what this memory usage value really means,
I'll revert the commit from
https://github.com/ovido/check_rhev3/issues/10
and set the memory usage to 0 if negative.
I never saw this issue in my environments or on customer sides, as we
normally always monitor vms using agents in the vm and not using
check_rhev3 for vms. I use it on some test machines in my environments,
but have KSM disabled, as it consumes too much CPU load when having
databases running in vms.
Workaround is to get the memory usage from polling agents which are
running directly in the vm like check_mk, snmp, nrpe,... until I can
receive the memory usage in the vm via REST-API and add it to
check_rhev3.

René

consumed on the hypervisor (this is pretty useless information
for me).
Is it planned to report the memory usage in a virtual machine
in the API
as well?

Guys,
these values are usually a result of overcommitment mechanism usage.
For example, if KSM is effective, it will free a lot of memory pages,
and total-free-committed becomes negative.
This was reported in https://bugzilla.redhat.com/show_bug.cgi?id=977758
and the engine is using memFree reported by vdsm, which is more accurate.
The API reports the old version due to backwards compatibility.
