[Openstack] ceilometer unable to collect compute.node.cpu.* data

Hi all,

I attempt to collect compute.node.cpu as the following link mentions:

http://docs.openstack.org/developer/ceilometer/measurements.html#compute-nova

I set:

compute_monitors = ComputeDriverCPUMonitor

in /etc/nova/nova.conf and restart nova-compute, nova-scheduler,
ceilometer-agent-notification, ceilometer-api, ceilometer-collector.

>From ceilometer-agent-notification's log, I can see agent transform and
publish data samples compute.node.cpu.*

What's more, from ceilometer database, I can see all the meters
compute.node.cpu.*

mysql> select * from meter;

+----+---------------------------------+------------+-----------+

| id | name                            | type       | unit      |

+----+---------------------------------+------------+-----------+

| 39 | compute.node.cpu.frequency      | gauge      | MHz       |

| 41 | compute.node.cpu.idle.percent   | gauge      | %         |

| 38 | compute.node.cpu.idle.time      | cumulative | ns        |

| 45 | compute.node.cpu.iowait.percent | gauge      | %         |

| 42 | compute.node.cpu.iowait.time    | cumulative | ns        |

| 36 | compute.node.cpu.kernel.percent | gauge      | %         |

| 44 | compute.node.cpu.kernel.time    | cumulative | ns        |

| 37 | compute.node.cpu.percent        | gauge      | %         |

| 43 | compute.node.cpu.user.percent   | gauge      | %         |

| 40 | compute.node.cpu.user.time      | cumulative | ns        |


However, when I type

ceilometer meter-list

It shows nothing about compute.node.cpu.*, so I wonder what's wrong with my
steps.
