By default ironic-inspector listens on, port can be changed in configuration. Protocol is JSON over HTTP.

Start Introspection

POST /v1/introspection/<UUID> initiate hardware introspection for node <UUID>. All power management configuration for this node needs to be done prior to calling the endpoint (except when Setting IPMI Credentials).

Requires X-Auth-Token header with Keystone token for authentication.

Optional parameters:

  • new_ipmi_password if set, ironic-inspector will try to set IPMI password on the machine to this value. Power credentials validation will be skipped and manual power on will be required. See Setting IPMI credentials for details.
  • new_ipmi_username provides new IPMI user name in addition to password set by new_ipmi_password. Defaults to current ipmi_username in node driver_info field.


  • 202 - accepted introspection request
  • 400 - bad request
  • 401, 403 - missing or invalid authentication
  • 404 - node cannot be found

Get Introspection Status

GET /v1/introspection/<UUID> get hardware introspection status.

Requires X-Auth-Token header with Keystone token for authentication.


  • 200 - OK
  • 400 - bad request
  • 401, 403 - missing or invalid authentication
  • 404 - node cannot be found

Response body: JSON dictionary with keys:

  • finished (boolean) whether introspection is finished
  • error error string or null

Ramdisk Callback

POST /v1/continue internal endpoint for the ramdisk to post back discovered data. Should not be used for anything other than implementing the ramdisk. Request body: JSON dictionary with at least these keys:

  • cpus number of CPU
  • cpu_arch architecture of the CPU
  • memory_mb RAM in MiB
  • local_gb hard drive size in GiB
  • interfaces dictionary filled with data from all NIC's, keys being interface names, values being dictionaries with keys:
    • mac MAC address
    • ip IP address
  • ipmi_address IP address of BMC, may be missing on VM
  • boot_interface optional MAC address of the NIC that the machine PXE booted from either in standard format 11:22:33:44:55:66 or in PXELinux BOOTIF format 01-11-22-33-44-55-66.
  • error optional error happened during ramdisk run, interpreted by ramdisk_error plugin
  • logs optional base64-encoded logs from the ramdisk
  • block_devices optional block devices information for root_device_hint plugin, dictionary with keys:
    • serials list of serial numbers of block devices.


This list highly depends on enabled plugins, provided above are expected keys for the default set of plugins. See Plugins for details.


This endpoint is not expected to be versioned, though versioning will work on it.


  • 200 - OK
  • 400 - bad request
  • 403 - node is not on introspection
  • 404 - node cannot be found or multiple nodes found

Response body: JSON dictionary. If Setting IPMI Credentials is requested, body will contain the following keys:

  • ipmi_setup_credentials boolean True
  • ipmi_username new IPMI user name
  • ipmi_password new IPMI password

Error Response

If an error happens during request processing, Ironic Inspector returns a response with an appropriate HTTP code set, e.g. 400 for bad request or 404 when something was not found (usually node in cache or node in ironic). The following JSON body is returned:

    "error": {
        "message": "Full error message"

This body may be extended in the future to include details that are more error specific.

API Versioning

The API supports optional API versioning. You can query for minimum and maximum API version supported by the server. You can also declare required API version in your requests, so that the server rejects request of unsupported version.


Versioning was introduced in Ironic Inspector 2.1.0.

All versions must be supplied as string in form of X.Y, where X is a major version and is always 1 for now, Y is a minor version.

  • If X-OpenStack-Ironic-Inspector-API-Version header is sent with request, the server will check if it supports this version. HTTP error 406 will be returned for unsupported API version.
  • All HTTP responses contain X-OpenStack-Ironic-Inspector-API-Minimum-Version and X-OpenStack-Ironic-Inspector-API-Maximum-Version headers with minimum and maximum API versions supported by the server.
