OpenStack Juno : How to use Ceilometer
2015/02/07 |
|
How to use the OpenStack Metering Service (Ceilometer).
This example is based on the environment like follows.
|
+------------------+ | +------------------------+
| [ Control Node ] | | | [ Network Node ] |
| Keystone |10.0.0.30 | 10.0.0.50| DHCP,L3,L2 Agent |
| Glance |------------+------------| Metadata Agent |
| Nova API |eth0 | eth0| Ceilometer Services |
| Neutron Server | | | |
+------------------+ | +------------------------+
eth0|10.0.0.51
+--------------------+
| [ Compute Node ] |
| Nova Compute |
| L2 Agent |
| Ceilometer-Compute |
+--------------------+
|
| [1] | After configuring Configure Ceilometer#1, Configure Ceilometer#2, Configure Ceilometer#3, if configuration of them are done normally, the command of follows answers without errors like follows. |

| [2] | It's possible to monitor Compute Service (Nova) now. Try to create and start an instance, and next, input the command meter-list again, then meters are loged like follows. |
