Dear all,
When we monitor one of our machines, we noticed that there was one vm that
was constantly giving a error of memory usage. But when we took a look at
it, there is actually nothing wrong with it. Now we looked furhter then
that. We looked at the API of the machine and noticed something very
strange:
<statistic
href="/api/vms/3b9aa245-75ff-42e8-b921-1c9ce61826bf/statistics/b7499508-c1c3-32f0-8174-c1783e57bb08"
id="b7499508-c1c3-32f0-8174-c1783e57bb08"><name>memory.used</name><description>Memory
used (agent)</description><values
type="INTEGER"><value><datum>*-944892806*
</datum></value></values><type>GAUGE</type><unit>BYTES</unit>
It's a negative...
What could be the problem?
Kind regards,
koen

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
