I'm looking for a way of how to meter the number of running instances (per
Currently, the Sum value in ceilometer statistics command's output is
confusing, mostly because the high number of notifications generated by nova
for each instance. As a result, also the graph in Resource Usage view does not
seem really useful at least for 'instances' meter.
(See https://bugs.launchpad.net/ceilometer/+bug/1396257 for this problem)
So, what is the correct way? Should I group the statistics output by
ceilometer statistics -m instance -q 'timestamp>2014-12-03T00' -g resource_id
and just count the number of resources in this output, which should (?) be the
number of running instances?
