Get started in three steps
Installation takes less than 2 minutes. Panellium runs as a WHM plugin — no external services, no agents.
Download the plugin
Download the Panellium WHM plugin installer. It's a standard cPanel plugin package — compatible with WHM on CentOS, AlmaLinux, and CloudLinux.
wget https://panellium.com/dl/install.sh
Run the installer
Execute the installer as root. It registers the plugin with WHM, creates the data directory, and configures log collection.
bash install.sh
Open in WHM
Log into WHM and find Panellium in the sidebar under Plugins → Resource Observability. The dashboard loads immediately with live data from your server.
