Proxmox Datacenter Manager: One Pane Over Every Cluster

Description and use

PDM consolidates multiple Proxmox clusters into a single read‑only dashboard using scoped API tokens.

Managing multiple Proxmox clusters requires juggling several browser tabs, making it hard to get a unified view of resources and health.

PDM provides a unified, read‑only view of multiple Proxmox clusters, reducing browser tab clutter and improving monitoring efficiency.

Deploy PDM in a Debian 13 LXC container using the no‑subscription repository and install the proxmox-datacenter-manager-container-meta package.
Configure the container’s web UI on port 8443 and log in as root@pam.
For each Proxmox cluster, create a dedicated read‑only user (PVEAuditor for VE, Audit for PBS) and generate an API token.
In PDM, add each cluster as a remote by entering the node address, allowing certificate fingerprint pinning, and pasting the token.
Verify that each remote appears in the PDM remotes table and that the dashboard aggregates resources across all clusters.

PDM ships as Debian packages, so a plain Debian 13 LXC does the job (2 vCPU / 2 GB RAM is plenty).

On each cluster, create a dedicated user and a read-only token rather than handing PDM an admin login.

With both remotes connected, the dashboard finally aggregates every node, guest, and datastore across separate clusters.
