Reset instance "Statistics"
Hello,
Anyone knows how often these values get reset or if at all?
http://img.nux.ro/fK7-Selection_016.png
I'm interested in tracking some of these values, but on a monthly basis or so.

Marcus,
Thanks, I'll have to give this a bit of thought and try to explain it to our dev. :)

Well, you should be able to do metering. The network and disk stats
are basically counters like you'd get from an SNMP call to a switch.
You have to calculate the diff between reads.

Oh right.
Was hoping I can do some sort of metering with them, as there are no usage network stats in a basic/adv+sg zone.
Thanks for the clarification. I'll have to resort to something else.

They are stored in memory. There's no history. For KVM there was/is a
bug in cpu stats where it grabs an average since uptime.
https://issues.apache.org/jira/browse/CLOUDSTACK-8247?filter=-1
It should be do-able to reset this concurrent hashmap to zero via api
call if someone wants to add that feature.

Would there be a way to persist this in the DB?
I'd imagine being able to sort VMs by these stats could be handy (who uses most IO, network or graph such usages per period and so on).

ACS, clearly.Once Management service restart, the samples all gone.

To clarify, these stats are kept in which memory? ACS's? Libvirt's?

Lucian,
These values get collected every minute (controlled by global config vm.stats.interval) from the hypervisor.
These values do not seem to be persisted in DB. I guess there won't be a need to reset these.
