Netbox Plugin - Integrate Proxmox and Netbox

Proxbox

Proxbox is a NetBox plugin that synchronizes Proxmox infrastructure data into NetBox. It keeps your DCIM up-to-date with real Proxmox clusters, nodes, virtual machines, containers, backups, and Firecracker micro-VM inventory used by the NMS Cloud runtime.

What It Does

Proxbox discovers and syncs the following from Proxmox into NetBox:

• Clusters and Nodes — Proxmox cluster name, mode (cluster/standalone), quorum status, node count, and Proxmox VE version. Each node includes online status, IP address, CPU usage, memory usage, and uptime at sync time. Optionally link to NetBox Cluster and Device objects.
• Virtual Machines — VM status, resources, and configuration
• Containers (LXC) — Container details and settings
• Firecracker Cloud inventory — Host pools, host-agent VMs, image templates, and provisioned micro-VMs exposed separately from QEMU/LXC for NMS Cloud provisioning
• VM Snapshots — Point-in-time snapshots for recovery
• VM Backups — Backup jobs and restore points
• Storage — Datastores and storage content
• Network Interfaces and IPs — Network interfaces and IP addresses assigned to VMs and containers
• Backup Routines — Backup job definitions from Proxmox
• Replications — Replication job status and configuration

Note: All metrics (CPU, memory, uptime, etc.) are captured as point-in-time snapshots at sync time, not continuous monitoring.

Sync runs on-demand from the NetBox UI or scheduled automatically via NetBox's job system.

Additional Optional Plugins

Proxbox can be extended with standalone companion plugins. Install only the plugins you need; netbox-proxbox remains the base plugin and must be enabled before any companion plugin. The infrastructure inventory plugins declare netbox-proxbox>=0.0.18 as a dependency, and netbox-packer follows the same operational conventions for the Proxbox plugin family.

Package	NetBox plugin	What it adds
netbox-pdm	netbox_pdm	Inventories Proxmox Datacenter Manager endpoints and the PVE/PBS remotes managed by PDM. It links PDM remotes back to Proxbox Proxmox endpoints and, when installed, netbox-pbs backup servers.
netbox-pbs	netbox_pbs	Inventories Proxmox Backup Server infrastructure, including PBS servers, datastores, backup snapshots, and scheduled job history.
netbox-ceph	netbox_ceph	Adds read-only Ceph cluster inventory for Proxmox-managed Ceph: clusters, daemons, OSDs, pools, filesystems, CRUSH rules, flags, and health checks.
netbox-packer	netbox_packer	Tracks HashiCorp Packer image definitions and build execution records for Proxmox VM templates and image-factory workflows.

For a standard NetBox virtualenv install, activate the NetBox environment and install the packages you want:

source /opt/netbox/venv/bin/activate
pip install netbox-pbs netbox-pdm netbox-ceph netbox-packer

Enable the selected plugins in netbox/netbox/configuration.py. Keep netbox_proxbox first. If you enable netbox_pdm, enable netbox_pbs before it because PDM can link to PBS server records.

PLUGINS = [
    "netbox_proxbox",
    "netbox_pbs",
    "netbox_pdm",
    "netbox_ceph",
    "netbox_packer",
]

Run migrations for the selected plugins, preserving the same order:

cd /opt/netbox/netbox
python3 manage.py migrate netbox_proxbox
python3 manage.py migrate netbox_pbs
python3 manage.py migrate netbox_pdm
python3 manage.py migrate netbox_ceph
python3 manage.py migrate netbox_packer
python3 manage.py collectstatic --no-input
sudo systemctl restart netbox netbox-rq

For netbox-docker, add the selected packages to plugin_requirements.txt, enable the matching plugin module names in configuration/plugins.py, rebuild, and run migrations:

netbox-pbs
netbox-pdm
netbox-ceph
netbox-packer

docker compose build
docker compose up -d
docker compose exec netbox /opt/netbox/netbox/manage.py migrate

Requirements

• NetBox 4.5.8, 4.5.9, or 4.6.x
• Verified with NetBox v4.5.8, v4.5.9, v4.6.0, and official v4.6.1
• Python 3.12+
• Proxmox VE 7.x, 8.x, or 9.x (PVE 9 requires VM.GuestAgent.Audit on the API role; see "Troubleshooting" below for the PVE 9 auth checklist)
• Proxbox API backend as a separately deployed service (see below)

Quick Start

Choose the installation path that matches your NetBox deployment:

• Standard NetBox install (venv on host): follow steps below.
• NetBox Docker install (netbox-docker): use the Docker-specific workflow in Installing the Plugin in Docker-Based NetBox Deployments.

1. Install the plugin into your NetBox virtual environment (host/venv deployment):

   cd /opt/netbox/netbox
   git clone https://github.com/emersonfelipesp/netbox-proxbox.git
   source /opt/netbox/venv/bin/activate
   pip install -e ./netbox-proxbox
   

2. Enable the plugin in netbox/netbox/configuration.py:

   PLUGINS = ["netbox_proxbox"]
   

3. Run migrations and collect static files:

   python3 manage.py migrate netbox_proxbox
   python3 manage.py collectstatic --no-input
   sudo systemctl restart netbox
   

4. Install the Proxbox API backend:

   mkdir -p /opt/proxbox-api
   cd /opt/proxbox-api
   python3 -m venv venv
   source venv/bin/activate
   pip install proxbox-api
   uvicorn proxbox_api.main:app --host 0.0.0.0 --port 8800
   

   Or use Docker (the published image runs nginx on port 8000 inside the container, in front of uvicorn):

   docker run -d --name proxbox-api -p 8800:8000 emersonfelipesp/proxbox-api:latest
   

   HTTPS with mkcert (optional): the backend also publishes emersonfelipesp/proxbox-api:latest-mkcert (and :<version>-mkcert). nginx terminates TLS there (mkcert certs) on PORT (default 8000); add more certificate names or IPs with MKCERT_EXTRA_NAMES (comma- or space-separated). Example:

   docker run -d --name proxbox-api-tls \
     -p 8800:8000 \
     -e MKCERT_EXTRA_NAMES='proxbox.backend.local' \
     emersonfelipesp/proxbox-api:latest-mkcert
   

   Point your NetBox ProxBox API endpoint at https://<host>:8800 (or your mapped port). Trust the mkcert root on clients if needed; see the proxbox-api README for build flags, CAROOT, and details.

5. Configure endpoints in NetBox:

   • Go to Plugins > Proxbox
   • Create a Proxmox API endpoint (your Proxmox host URL and token). The Proxmox user/token must hold a role with Datastore.Audit, Sys.Audit, VM.Audit, VM.Monitor, and VM.GuestAgent.Audit. VM.GuestAgent.Audit is required on Proxmox VE >= 9 for the backend to pull VM IPs through the QEMU guest agent — without it, VMs sync but their IP addresses are missing from NetBox. See the proxbox-api docs Required Proxmox role privileges for the pveum role add command.
   • Create a NetBox API endpoint (your NetBox URL and token)
   • Create a ProxBox API endpoint (the backend from step 4)

6. Run your first sync:

   Click Full Update on the Proxbox home page. Progress appears in real-time.

NetBox Docker Install Option

If your NetBox runs with netbox-community/netbox-docker, install the plugin through the Docker plugin files in your NetBox Docker project:

1. Add plugin requirements to plugin_requirements.txt (PyPI or Git):

   netbox-proxbox
   # or
   # netbox-proxbox @ git+https://github.com/emersonfelipesp/netbox-proxbox.git
   

2. Enable the plugin in configuration/plugins.py:

   PLUGINS = ["netbox_proxbox"]
   

3. Rebuild and restart NetBox:

   docker compose build
   docker compose up -d
   

4. Run migrations in the NetBox container:

   docker compose exec netbox /opt/netbox/netbox/manage.py migrate
   

For complete Docker installation instructions, validation checks, and Git/source install examples, see docs/installation/3-installing-plugin-docker.md.

Scheduled Sync

Proxbox sync jobs run on NetBox's default RQ queue. A standard NetBox installation already ships a netbox-rq systemd service that runs:

manage.py rqworker high default low

Check whether it is running before doing anything else:

sudo systemctl status netbox-rq

If it is active (running), you have nothing extra to configure — Proxbox jobs will be picked up automatically.

If the service is inactive or missing, enable it:

sudo systemctl enable --now netbox-rq

The unit file is provided by NetBox at contrib/netbox-rq.service in the NetBox repository. If you need to create it manually, copy it from there and run:

sudo systemctl daemon-reload
sudo systemctl enable --now netbox-rq

Upgrading from an older Proxbox release? Jobs used to be enqueued on the netbox_proxbox.sync queue. The stock netbox-rq service does not listen to that queue, so old-style jobs will not run. New jobs always use default and are picked up without any changes.

Schedule a sync

1. In NetBox, go to Proxbox > Schedule Sync.
2. Choose one or more sync types (All, Devices, VMs, Storage, etc.).
3. Optionally set a Schedule at time and a Recurs every interval in minutes (e.g. 1440 for daily).
4. Click Schedule.

Track job status under Proxbox > Sync Jobs or Operations > Background Jobs.

Job timeout

Proxbox sync jobs default to a 7200-second (2-hour) RQ wall-clock limit (PROXBOX_SYNC_JOB_TIMEOUT). NetBox's default RQ_DEFAULT_TIMEOUT is only 300 s, which would kill long syncs. No configuration is needed unless your syncs routinely take longer than two hours; if they do, override the constant in netbox_proxbox/jobs.py.

Troubleshooting

Symptom	Likely cause	Fix
Job stays pending	No RQ worker running, or worker not listening to default queue	Start/restart manage.py rqworker
Job stays running for a long time	Proxbox API is still syncing or stream is slow	Check the job Log tab; wait or inspect the backend
Job errored: JobTimeoutException	RQ wall-clock limit exceeded	Increase PROXBOX_SYNC_JOB_TIMEOUT in netbox_proxbox/jobs.py
VM IP addresses stay empty after upgrade	The separate proxbox-api backend is too old, is on the v0.0.13/v0.0.14 agent-flag warning window, existing VMs still lack proxmox_vm_id, or the Proxmox role lacks guest-agent privileges	Check the FastAPI card warning on the Proxbox home page. Run proxbox-api >= 0.0.13 at minimum; if the warning references PR #156, install a backend build containing that fix or the next fixed backend release. Then run Full Update so existing VMs get proxmox_vm_id before the IP-address stage runs. For PVE 9, also confirm VM.GuestAgent.Audit.
HTTP 401 Authentication failed! against Proxmox VE 9.x	A stale stored token is overriding fresh password credentials, or the role is missing PVE 9 permissions	On the Proxmox endpoint edit page, tick "Clear stored API token on save" (and/or "Clear stored password on save") to wipe the unused secret. The form rejects rows that end up with neither a password nor a complete (token name, token value) pair. Confirm the role on Proxmox grants Datastore.Audit, Sys.Audit, VM.Audit, and on PVE 9 also VM.GuestAgent.Audit. The plugin now surfaces the upstream PVE 9 error message in the UI instead of "Unknown error.", which makes "no such realm" / "expired token" / "missing privilege" failures self-diagnosing.

Switching credentials cleanly (PVE 9 friendly)

The Proxmox endpoint edit form preserves the stored password and token value when you submit blank masked fields — that is intentional for partial edits. When you genuinely want to switch auth modes (for example, password → token or vice versa, or rotate a leaked secret), tick the matching "Clear stored …" checkbox so the unused credential is wiped on save. Clearing the token always clears both token name and token value together so the row never persists in a half-token state.
