The same servers are presented under three filtered lists — **Web**, **Mail** and **DNS** — based on their capabilities. ![Web servers](https://doc.puq.info/uploads/images/gallery/2026-06/embedded-image-yzikthtf.png) Each row carries live **CPU / RAM / Disk / Load** bars, the panel‑OK probe, the Hestia version & OS, the group, the capacity used/max, and per‑row actions (open Server Actions, refresh status, sync, edit, delete). ## Capabilities decide the pools A node's **Web / Mail / DNS** capability flags decide which list it appears in and which roles can be placed on it. See **Add web / mail / DNS servers** for the editor and **Deployment & Segmentation → Server segmentation** for how to design your topology. ![Mail servers](https://doc.puq.info/uploads/images/gallery/2026-06/embedded-image-twhxky1a.png) DNS servers are independent and attached to groups (one server can serve many groups): ![DNS servers](https://doc.puq.info/uploads/images/gallery/2026-06/embedded-image-ni2clyu3.png) ## Open a server → Server Actions Clicking a server's open/manage action takes you to the **Server Actions** page for that node — a full per‑node management console (live config, group‑config drift, PHP versions, file‑manager installs, system services, Hestia users & packages, IPs, maintenance, logs). That page is documented next.
