20.3. 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
+-----------+-------------------+------------------------+-------------------+----------------+
| Interface | MAC Address       | Switch Port VLAN IDs   | Switch Chassis ID | Switch Port ID |
+-----------+-------------------+------------------------+-------------------+----------------+
| 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

裸机服务 hardware-inspection-extras 功能默认启用,您可以使用它来检索 overcloud 配置的硬件详情。有关 undercloud.conf 文件中的 inspection_extras 参数的更多信息,请参阅配置 Director

例如,numa_topology 收集程序就是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

要获得以上列出的信息,请使用裸机节点的 UUID 替换 <UUID> 来完成以下命令:

# openstack baremetal introspection data save <UUID> | jq .numa_topology

以下示例显示获取的裸机节点 NUMA 信息:
