红帽全球峰会17.3. 执行网络内省以查看接口信息
网络内省会从网络交换机获取链路层发现协议 (LLDP) 数据。以下命令可显示某个节点上所有接口的某个 LLDP 信息子集，或显示某个节点和接口的全部信息。这对故障排除非常有用。director 默认会启用 LLDP 数据收集。
要获取节点上的接口列表，请运行以下命令：
(undercloud) $ openstack baremetal introspection interface list [NODE UUID]例如：
(undercloud) $ openstack baremetal introspection interface list c89397b7-a326-41a0-907d-79f8b86c7cd9
+-----------+-------------------+------------------------+-------------------+----------------+

+-----------+-------------------+------------------------+-------------------+----------------+
| p2p2 | 00:0a:f7:79:93:19 | [103, 102, 18, 20, 42] | 64:64:9b:31:12:00 | 510 |
| p2p1 | 00:0a:f7:79:93:18 | [101] | 64:64:9b:31:12:00 | 507 |
| em1 | c8:1f:66:c7:e8:2f | [162] | 08:81:f4:a6:b3:80 | 515 |
| em2 | c8:1f:66:c7:e8:30 | [182, 183] | 08:81:f4:a6:b3:80 | 559 |
+-----------+-------------------+------------------------+-------------------+----------------+要查看接口数据和交换机端口信息，请运行以下命令：
(undercloud) $ openstack baremetal introspection interface show [NODE UUID] [INTERFACE]例如：
(undercloud) $ openstack baremetal introspection interface show c89397b7-a326-41a0-907d-79f8b86c7cd9 p2p1

+--------------------------------------+------------------------------------------------------------------------------------------------------------------------+获取硬件内省详细信息
Bare Metal 服务的硬件检查额外功能 (inspection_extras) 会默认启用，以获取硬件详细信息。您可以使用这些硬件详细信息来配置 overcloud。请参见配置 Director，详细了解 undercloud.conf 文件中的 inspection_extras 参数。
例如，numa_topology 收集程序就是这些硬件检查额外功能的一部分，包括每个 NUMA 节点的以下信息：
- RAM（单位为 KB）
- 物理 CPU 内核数和同级线程数
- 和 NUMA 节点关联的 NIC
使用 openstack baremetal introspection data save _UUID_ | jq .numa_topology 命令并提供裸机节点的 UUID 以获取这些信息。
以下示例显示获取的裸机节点 NUMA 信息：
