+title: Proxmox
+description: Proxmox Configuration
+---
+
+The Proxmox connection is configured in the `proxmox.yaml` file. See [Create token](#create-token) section below for details on how to generate the required API token.
+
+```yaml
+url: https://proxmox.host.or.ip:8006
+token: username@pam!Token ID
+secret: secret
+```
+
+## Services
+
+Once the Proxmox connection is configured, individual services can be configured to pull statistics of VMs or LXCs. Only CPU and Memory are currently supported.
+
+### Configuration Options
+
+- `proxmoxNode`: The name of the Proxmox node where your VM/LXC is running
+- `proxmoxVMID`: The ID of the Proxmox VM or LXC container
+- `proxmoxType`: (Optional) The type of Proxmox virtual machine. Defaults to `qemu` for VMs, but can be set to `lxc` for LXC containers
+
+#### Examples
+
+For a QEMU VM (default):
+
+```yaml
+- HomeAssistant:
+  icon: home-assistant.png
+  href: http://homeassistant.local/
+  description: Home automation
+  proxmoxNode: pve
+  proxmoxVMID: 101
+  # proxmoxType: qemu # This is the default, so it can be omitted
+```
+
+For an LXC container:
+
+```yaml
+- Nginx:
+  icon: nginx.png
+  href: http://nginx.local/
+  description: Web server
+  proxmoxNode: pve
+  proxmoxVMID: 200
+  proxmoxType: lxc
+```
+
+## Create token
+
+You will need to generate an API Token for new or an existing user. Here is an example of how to do this for a new user.
+
+1.  Navigate to the Proxmox portal, click on Datacenter
+2.  Expand Permissions, click on Groups
+3.  Click the Create button
+4.  Name the group something informative, like api-ro-users
+5.  Click on the Permissions "folder"
+6.  Click Add -> Group Permission
+    - Path: /
+    - Group: group from bullet 4 above
+    - Role: PVEAuditor
+    - Propagate: Checked
+7.  Expand Permissions, click on Users
+8.  Click the Add button
+    - User name: something informative like `api`
+    - Realm: Linux PAM standard authentication
+    - Group: group from bullet 4 above
+9.  Expand Permissions, click on API Tokens
+10. Click the Add button
+    - User: user from bullet 8 above
+    - Token ID: something informative like the application or purpose like `homepage`
+    - Privilege Separation: Checked
+11. Go back to the "Permissions" menu
+12. Click Add -> API Token Permission
+    - Path: /
+    - API Token: select the Token ID created in Step 10
+    - Role: PVE Auditor
+    - Propagate: Checked
