Chapter 13. Additional introspection operations

13.1. Performing Individual Node Introspection
Link kopieren

To perform a single introspection on an available node, run the following commands to set the node to management mode and perform the introspection: 

(undercloud) $ openstack baremetal node manage [NODE UUID]
(undercloud) $ openstack overcloud node introspect [NODE UUID] --provide

After the introspection completes, the node changes to an available state.

13.2. Performing Node Introspection after Initial Introspection
Link kopieren

After an initial introspection, all nodes should 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: 

(undercloud) $ for node in $(openstack baremetal node list --fields uuid -f value) ; do openstack baremetal node manage $node ; done
(undercloud) $ openstack overcloud node introspect --all-manageable --provide

After the introspection completes, all nodes change to an available state.

13.3. Performing Network Introspection for Interface Information
Link kopieren

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. The director enables LLDP data collection by default.

To get a list of interfaces on a node, run the following command: 

(undercloud) $ openstack baremetal introspection interface list [NODE UUID]

For example: 

(undercloud) $ openstack baremetal introspection interface list c89397b7-a326-41a0-907d-79f8b86c7cd9

Retrieving Hardware Introspection Details

The Bare Metal service hardware inspection extras (inspection_extras) is enabled by default to retrieve hardware details. You can use these hardware details to configure your overcloud. See Configuring the Director for details on the inspection_extras parameter in the undercloud.conf file.

For example, the numa_topology collector is part of these 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

Use the openstack baremetal introspection data save _UUID_ | jq .numa_topology command to retrieve this information, with the UUID of the bare-metal node.

The following example shows the retrieved NUMA information for a bare-metal node: 

{

    {
      "cpu": 1,
      "thread_siblings": [
