流程

1. 列出现有的 Telemetry 警报：

   # openstack alarm list
   +--------------------------------------+--------------------------------------------+----------------------------+-------------------+----------+---------+
   | alarm_id                             | type                                       | name                       | state             | severity | enabled |
   +--------------------------------------+--------------------------------------------+----------------------------+-------------------+----------+---------+
   | 922f899c-27c8-4c7d-a2cf-107be51ca90a | gnocchi_aggregation_by_resources_threshold | iops-monitor-read-requests | insufficient data | low      | True    |
   +--------------------------------------+--------------------------------------------+----------------------------+-------------------+----------+---------+

2. 要列出分配给资源的计量，请指定资源的 UUID。例如：

   # openstack metric resource show 22592ae1-922a-4f51-b935-20c938f48753
