Ceilometer CLI, e.g.

ceilometer sample-list --query "resource=INSTANCE_ID;meter=cpu_util"

The Gnochi CLI probably achieves the same.

If you prefer, there is also the Ceilometer or Gnocchi API.

The list of existing meters is documented.

How long has your instance been running? Samples are taken every ten minutes by default. Apart from that, all I can say is that it worked for me.

I don't know enough about the internals of Ceilometer and Gnocchi (the latter being the component that manages the accumulated samples) to help you troubleshoot this.
