Data model for Proxmox

This extension is dedicated to Proxmox, the server virtualization platform that automates the management of virtual machines. It enhances iTop's CMDB by modelizing Proxmox elements that are not part of iTop's default CIs (Clusters, Storage, Containers…) and by adding attributes to some of the existing devices (Servers, Virtual Machines). Combined with the Data collector for Proxmox, it allows Proxmox administrators to fetch in iTop the key elements of their Proxmox infrastructure.

When installed on iTop, the extension creates or enhances a set of classes dedicated to or related to Proxmox virtualization environments:

• Creations
  • Proxmox clusters
  • Proxmox High Availability groups
  • Proxmox containers
  • Proxmox disks
  • Proxmox storage
  • Proxmox storage type
  • Link High Availability groups / servers

• Enhancements
  • Servers
  • Virtual Machines

None

The extension can only be installed on iTop 3.2.0 and above, where Virtualization Management has been activated.

Use the Standard installation process for this extension.

No specific configuration is required.

A Proxmox cluster is a group of physical servers that are pooled together and share resources to provide an overall fault tolerant system for hosting virtual machines and containers.

Enter the Class name in the Quick create area to create a new object, then fill out the form and press the Create button.

This tab provides overall figures on the virtual machines and containers hosted by the cluster.

• Impacts: A Proxmox cluster impacts the nodes that belong to it.
• Depends on: N/A

The class Server is used in iTop to document Proxmox nodes. The Proxmox datamodel extension enriches the server attributes, brought by iTop standard datamodel, with a few meaningful attributes that are documented in a Proxmox environment. These can of course be reused for non-Proxmox servers.

This tab provides global figures on the virtual machines and containers hosted by the node.

• Impacts: A Proxmox node impacts the HA groups to which it belongs, depending to the redundancy parameters that have been defined for each of the groups.
• Depends on: It simply depends on its Proxmox cluster.

A HA Group is a subset of nodes linked together in order to provide a high-availability environment for resources hosted on the nodes, including virtual machines and containers.

• Impacts: A Proxmox HA Group impacts the virtual machines and the containers it hosts.
• Depends on: It depends on the different nodes that look after it, thus offering redundancy.

A Virtual Machine is the virtual equivalent of a Server. It is hosted either on an Hypervisor, on a Farm in the vSphere world or on a Node in the Proxmox world. The Proxmox datamodel extension enriches the virtual machine attributes, brought by iTop standard datamodel, with a few meaningful attributes that are documented in a Proxmox environment. These can of course be reused for non-Proxmox VMs.

* The extension is making the virtual host NOT mandatory.

• Impacts: a Virtual Machine impacts the software intances running on it, the Application Solutions which this VM is part of and all the contacts (Persons, Teams) directly linked to the VM.
• Depends on: from a Proxmox standpoint, a Virtual Machine depends on the HA Group to which it belongs.

A Proxmox container is a lightweight virtualisation solution based on LXC (Linux Containers) technology. It allows you to create and manage isolated environments that share the host system's Linux kernel, unlike traditional virtual machines that emulate hardware and require their own operating system.

• Impacts: a Proxmox container impacts the software intances running on it, the Application Solutions which this container is part of and all the contacts (Persons, Teams) directly linked to the container.
• Depends on: from a Proxmox standpoint, a container depends on the HA Group to which it belongs.

This typology class enables administrators to type the Proxmox Storages in alignment with Proxmox pre-defined types.

Proxmox storage refers to the spaces in which Proxmox will store backups, virtual disks, bootable ISOs, etc. A wide range of storage types are supported, the simplest being an regular directory, while the most complex uses redundant systems such as Ceph.

Proxmox disk simply documents the hardware disks hosted within Proxmox nodes, i.e. servers.
