Open Stack

Hi there

I'm facing a strange ceilometer-api behavior. While I can query 
ceilometer-api for "meter-list"/"sample-list" (or even openstack usage 
show) very fast, it looks like ceilometer cli (or api) struggles with 
"ceilometer statistics" gettting always a timeout

[user1 at ubuntu ~]$ ceilometer statistics -q 
"project=6294315f9df1491fa9345701d2642c96;timestamp>2016-06-20T14:30" -m 
vcpus --period 60
b'Gateway Timeout (HTTP 504)'

Would you happen to know why? Any idea/clue?

Thanks.
J
