Hey Jobin,
Thanks for your perceptive question.
The reason is that the conduits for gathering CPU metering and memory
metering are quite different in ceilometer currently:
* cpu/cpu_util are derived by polling the libvirt daemon
* memory is derived from the compute.instance.exists

Thanks for putting this together Sandy,
if you have:
Time | Value
0 | 10
1 | 30

If your delta-pollster is down at 1 and 2, you restart at 3,
therefore at 4 you'll send 20 as usage (100 minus 80).
So you miss the delta between 10 (time 0) and 80 (time 3)
(therefore 70 for free!). If
Hi Yawei Wu,
The root of the confusion is the fact the cpu meter is reporting
the cumlative cpu_time stat from libvirt. This libvirt counter is
reset when the associated qemu process is restarted (an artifact
of how cpuacct works).
So when you stop/start or suspend/resume, a fresh qemu process
Not at all. It means the CPU time consumed is reset to 0, but
that's not an issue in itself, the API should be capable to
deal with that if you ask for the total usage.
Would that total usage be much more apparent if we started
metering the delta between CPU times on subsequent polling
I don't think (max - min) would suffice to give an accurate
measure of the actual CPU time used, as the counter may have
reset multiple times in the course of the requested duration.
It is, because /max in the API should be aware of the fact a
reset can occur and computes accordingly.
If your pollster is not running to compute delta and you have
no state stored, you'll miss a part of what has been used.
Would we have also have some 'misses' with the cumulative approach
when the ceilometer agent was down?
If I understood the (\Sigma local maxima)-first idea correctly,

Would we have also have some 'misses' with the cumulative approach

No, unless the counter resets several times while your agent is down.

Hi Vijaya,
I don't think a new nova command is needed for this use-case,
just add a simple custom script:
nova quota-update `nova quota-defaults $1 | tail
Isn't that just changing one custom limit with another ?

Florian,
The key point in the split between glance-api.conf, glance-registry.conf,
glance-cache.conf etc. is the glance application intended to consume that
config.
This follows directly from the naming:
bin/glance-api by default consumes glance-api.conf
bin/glance-registry by default
Yes, it does make perfect sense. Kind thanks for the explanation.
However, what is still unclear is what config iteems that pertain to

This is probably something we should document more
