OPCP - How to see the node inventory

Objective

This guide explains how to view the hardware inventory, consumed resources, and available resources on an OVHcloud On-Prem Cloud Platform (OPCP) using:

• Grafana: real-time infrastructure monitoring
• NetBox: physical and logical inventory
• OpenStack Horizon: Ironic inventory via Horizon
• OpenStack CLI: Ironic inventory via CLI

Prerequisites

• Being an administrator of the OPCP infrastructure and have access to the administration interface admin.dashboard.
• OpenStack CLI configured with the required permissions (clouds.yaml or environment variables).

Instructions

1. Inventory and monitoring via Grafana

Grafana provides a real-time monitoring view and allows you to easily track changes in your OPCP infrastructure.

1.1 Access the Home dashboard

1. Log in to the administration URL admin.dashboard.
2. Click Grafana.
3. Click Dashboards and search for the OpenStack overview dashboard.

You should see a dashboard similar to the following image:

1.2 Understanding the OpenStack overview dashboard

The dashboard allows you to visualize:

• OpenStack service status: Service status
• Resource usage: Resource usage
• A detailed view of the Keystone service: Keystone
• A detailed view of the Ironic service: Ironic
• A detailed view of the Nova service: Nova
• A detailed view of the Neutron service: Neutron
• A detailed view of the Cinder service: Cinder
• A detailed view of the Glance service: Glance

1.3 Understanding and using the Ironic section

We will focus on the "Ironic" section, as this is where you can see the status of the different nodes.

This section allows you to view:

• Total number of nodes: Total enrolled Ironic nodes
• Number of available nodes not in maintenance: Available Ironic nodes
• Number of nodes in error: Error Ironic nodes
• List of nodes in error or maintenance: List of failed and maintenance nodes
• Number of allocated nodes: Allocated Ironic nodes
• Number of waiting nodes: Waiting Ironic nodes
• Number of nodes in maintenance: Maintenance Ironic nodes

2. Hardware and logical inventory with NetBox

NetBox is the reference tool for managing the physical, network, and logical inventory of your infrastructure.

The NetBox inventory is automatically populated; no manual action is required to add or modify nodes.

2.1 Access NetBox

1. Log in to the administration URL admin.dashboard.
2. Click NetBox.

2.2 View the node inventory

In Devices, you can see the complete list of equipment in your OPCP rack (nodes, network equipment, etc.).

You can:

• use the quick search to find an item by name;
• use Filters for advanced searches.

For example, you can list all non-production nodes by applying the following filters:

• Status: Decommissioned, Inventory, Failed, Planned
• Role: server

You can save the search to reuse it later.

3. OpenStack Horizon – Ironic UI

3.1 Access the Ironic interface

1. Log in to the administration URL admin.dashboard
2. Click Horizon
3. Click Admin
4. Click System, then Ironic Bare Metal Provisioning

3.2 List all nodes

In Ironic Bare Metal Provisioning, you can see all nodes.

You can filter nodes by their status, for example: Provisioning State = failed.

4. Resource status via OpenStack CLI

The OpenStack CLI allows you to obtain the real-time status of allocated and available resources.

4.1 List all nodes

openstack baremetal node list

Example output:

+--------------------------------------+----------------+--------------------------------------+-------------+--------------------+-------------+
| UUID                                 | Name           | Instance UUID                        | Power State | Provisioning State | Maintenance |
+--------------------------------------+----------------+--------------------------------------+-------------+--------------------+-------------+
| 88830859-5b16-4935-8f41-d381b754cbe5 | SERVER-1       | None                                 | power off   | available          | False       |
| 726bb7e9-3b20-4a44-99d7-2af747983781 | SERVER-2       | None                                 | power off   | available          | False       |
| af711edf-a579-491e-b474-3c03639ed99b | SERVER-3       | 83b7083b-bbdd-4327-941c-ee91197818c5 | power on    | active             | False       |
+--------------------------------------+----------------+--------------------------------------+-------------+--------------------+-------------+

4.2 Filter nodes

You can filter results using --provision-state to view nodes in a specific state, or --maintenance to view nodes in maintenance.

All available filters can be found using --help.

Example output:

$ openstack baremetal node list --provision-state "clean failed"
+--------------------------------------+----------------+---------------+-------------+--------------------+-------------+
| UUID                                 | Name           | Instance UUID | Power State | Provisioning State | Maintenance |
+--------------------------------------+----------------+---------------+-------------+--------------------+-------------+
| 37f96160-16cf-47e6-8bee-0ee42a59fafe | SERVER-1       | None          | power off   | clean failed       | False       |
| 5678b6ff-1909-466f-857a-c8818a5ecd61 | SERVER-2       | None          | power off   | clean failed       | False       |
| cf5ee1ce-913a-4bff-a343-c391d8b3b667 | SERVER-3       | None          | power off   | clean failed       | False       |
+--------------------------------------+----------------+---------------+-------------+--------------------+-------------+

$ openstack baremetal node list --maintenance
+--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+
| UUID                                 | Name         | Instance UUID                        | Power State | Provisioning State | Maintenance |
+--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+
| 4e1108e1-3049-46fc-adb5-b27ba607710d | SERVER-4     | 9b972076-2c58-496b-9690-0f1b40d54660 | None        | deploy failed      | True        |
+--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+

4.3 Node details

To retrieve all information about a node, for example to identify the last error and understand why the deployment failed:

openstack baremetal node show <node-id>
