# Detailed Node

**Detailed Node** is a deep-dive view of a single device. Open it from **TB Nodes > Detailed Node**, or by clicking a device name in [All Nodes](/maas-documentation/monitoring/all-nodes.md).

Select a host from the dropdown (or use `?hostid=XXXX` in the URL) to load its full detail.

## Sections

Each section can be **collapsed by clicking its title**. Collapsed sections stop refreshing — useful if you only want to watch one thing.

### System Status

Per-host HA states, CPU, RAM, disk, reboot and license flags. Includes time-series charts for CPU, RAM, disk, and per-application CPU with a **2h / 6h / 24h / 7d / 30d / 90d** range selector.

### Call Statistics

Active calls, call legs, CPS, and an incoming/outgoing breakdown. Includes Call Legs and CPS charts with their own range selector (2h / 6h / 24h / 7d / 30d / 90d).

The **7d view** overlays the current week against the previous three weeks for quick week-over-week comparison. **30d and 90d** show the full period as a flat trend line.

### Firewall (ProSBC only)

Active firewall alarms — DDoS, scheduling, high-CPU, etc.

### NAPs

Per-NAP call legs, CPS, MOS quality, and availability. One row per NAP.

### NAP Trends

A configurable chart showing selected NAPs and metrics — inbound and outbound call legs and CPS — over time. Pick NAPs from the dropdown, choose metrics, set the range. Your selections persist across page reloads.

### Adapters (TMG only)

Per-adapter status, HA state, and CPU.

### TDM Lines (TMG only)

DS3, E1/T1, and STM1 interface status.

### Problems

All active triggers on this device, with severity.

***

## Refresh Behavior

* Short time ranges (≤24h) refresh quickly; longer ranges refresh less often because trend data barely moves minute-to-minute.
* Refresh pauses when the tab is backgrounded or when a section is collapsed.
* Returning to the tab (or expanding a section) triggers an immediate catch-up fetch — you never see stale values.

## Deep Linking

Add `&hostid=XXXX` to the URL to open a specific device directly. Clicking a host name from [All Nodes](/maas-documentation/monitoring/all-nodes.md) does this automatically.
