Chapter 19. Additional introspection operations 19.1. Performing individual node introspection To perform a single introspection on an available node, run the following commands to set the node to management mode and perform the introspection: After the introspection completes, the node changes to an available state. 19.2. Performing node introspection after initial introspection After an initial introspection, all nodes enter an available state due to the --provide option. To perform introspection on all nodes after the initial introspection, set all nodes to a manageable state and run the bulk introspection command: After the introspection completes, all nodes change to an available state. 19.3. Performing network introspection for interface information Network introspection retrieves link layer discovery protocol (LLDP) data from network switches. The following commands show a subset of LLDP information for all interfaces on a node, or full information for a particular node and interface. This can be useful for troubleshooting. Director enables LLDP data collection by default. To get a list of interfaces on a node, run the following command: For example: To view interface data and switch port information, run the following command: For example: Retrieving hardware introspection details The Bare Metal service hardware-inspection-extras feature is enabled by default, and you can use it to retrieve hardware details for overcloud configuration. For more information about the inspection_extras parameter in the undercloud.conf file, see Configuring the Director . For example, the numa_topology collector is part of the hardware-inspection extras and includes the following information for each NUMA node: RAM (in kilobytes) Physical CPU cores and their sibling threads NICs associated with the NUMA node To retrieve the information listed above, substitute <UUID> with the UUID of the bare-metal node to complete the following command: The following example shows the retrieved NUMA information for a bare-metal node:
