我昨天安装了Openstack Ceilometer。并且有一个名为c4371f8f-6e4b-41b0-8c2f-3857fe8e38a4的资源id。我使用ceilometer meter-list -q resource_id=c4371f8f-6e4b-41b0-8c2f-3857fe8e38a4来显示仪表。这是详细数据：

我使用ceilometer sample-list -q resource_id=c4371f8f-6e4b-41b0-8c2f-3857fe8e38a4 -m disk.write.bytes来查看disk.write.bytes。这是显示：

现在，问题来了。我想看看one of the disk.write.bytes的数据。这个shell是怎么写的？有人帮我吗？非常感谢！
ceilometer sample-list -q resource_id=c4371f8f-6e4b-41b0-8c2f-3857fe8e38a4 -m disk.write.bytes -l 1
-l 1或--limit 1将只返回一个结果
同时，您可以使用ceilometer --debug sample-list -q resource_id=c4371f8f-6e4b-41b0-8c2f-3857fe8e38a4 -m disk.write.bytes -l 1查看详细信息
