4.6. 查看云使用量措施

流程

1. 为 Telemetry 创建一个 YAML 文件，如 ceilometer-environment.yaml。
2. 在 ceilometer-environment.yaml 文件中，将 cmt 添加到 LibvirtEnabledPerfEvents 参数。如需更多信息，请参阅 /usr/share/openstack-triple-heat-templates/puppet/services/nova_libvirt.yaml。

3. 使用此 YAML 文件部署 overcloud。使用 <existing_overcloud_environment_files> 属于现有部署一部分的环境文件列表替换：

    #!/bin/bash
   
     openstack overcloud deploy \
     --templates \
     <existing_overcloud_environment_files> \
     -e  /home/stack/ceilometer-environment.yaml \
     ...

4. 验证 Compute 节点上的 Gnocchi 中是否启用了 cpu_l3_cache。

   $ sudo -i
   # docker exec -ti ceilometer_agent_compute cat /etc/ceilometer/gnocchi_resources.yaml | grep cpu_l3_cache
   //Verify that cpu_l3_cache is enabled for Telemetry polling.
   # docker exec -ti ceilometer_agent_compute cat /etc/ceilometer/polling.yaml  | grep cpu_l3_cache
   //If cpu_l3_cache is not enabled for Telemetry, enable it and restart the service.
   # docker exec -ti ceilometer_agent_compute echo "        - cpu_l3_cache" >> /etc/ceilometer/polling.yaml
   # docker exec -ti ceilometer_agent_compute pkill -HUP -f "ceilometer.*master process"

   注意

   更改容器镜像中的设置不会在重新引导后保留。

5. 在此 Compute 节点上启动客户端实例后，监控 CMT 指标：

   (overcloud) [stack@undercloud-0 ~]$ openstack metric measures show --resource-id a6491d92-b2c8-4f6d-94ba-edc9dfde23ac cpu_l3_cache
