验证操作

验证遥测服务的操作。这些步骤仅包含镜像服务的计量器，以减少混乱。与 Ceilometer 集成的其他服务的环境包含更多的计量器。

注意

在控制器节点上执行以下步骤。

注意

以下使用 Gnocchi 验证数据。或者，可以使用 file:// 发布者将数据临时发布到文件后端。

1. 激活 admin 凭证以访问仅管理员可用的 CLI 命令

   $ . admin-openrc
   

2. 列出可用的资源及其计量器

   $ gnocchi resource list  --type image

3. 从镜像服务下载 CirrOS 镜像

   $ IMAGE_ID=$(glance image-list | grep 'cirros' | awk '{ print $2 }')
   $ glance image-download $IMAGE_ID > /tmp/cirros.img
   

4. 再次列出可用的计量器，以验证镜像下载的检测

   $ gnocchi measures show 839afa02-1668-4922-a33e-6b6ea7780715
   +---------------------------+-------------+-----------+
   | timestamp                 | granularity |     value |
   +---------------------------+-------------+-----------+
   | 2017-01-26T15:35:00+00:00 |       300.0 | 3740163.0 |
   +---------------------------+-------------+-----------+
   

5. 删除先前下载的镜像文件 /tmp/cirros.img

   $ rm /tmp/cirros.img
