Hi, I'm trying to retrieve the last samples of ceilometer in order to have the instantaneous values of the diferent metrics but the most recents samples I manage to have are one hour old. It seems that ceilometer looks for the samples in OldSamples objects when I ask for ceilometer.sample_list(request, meter_name=u'cpu'). Can anybody help me to find the last samples of ceilometer measured ? (I have configured ceilometer to record the measures every minute) Thx for your help

It seems that MongoDB does not register the samples instantaneously. The one hour latency may thus come from the RPC publisher, but I still can't find where these samples are stored during this hour and how to reduce this latency. Any lead or start of lead ? Thanks

Ok, I've just found out that I hadn't the same timezone configuration on my computer (UTC+0100) and on openstack (UTC). So I actually had the last samples but it was the timestamp field that was wrong. Thus I've changed the timezone of openstack from the dashboard (in Parameters) and in the /etc/openstack-dashboard/local_settings.py file. Nevertheless I still have a wrong timestamp associated to my samples and I don't know how to modify it...
