NOC Display
A full-screen, low-chrome view of your dashboards designed for wall-mounted monitors in a Network Operations Centre. It cycles through your saved dashboards on a timer and visually escalates when alert counts climb.
The NOC Display reuses the same dashboards you build on the Dashboard (chapter 07) page. The difference is the presentation. Instead of editing widgets and digging into details, the NOC view is read-only, runs in fullscreen, hides operator chrome, and rotates through dashboards automatically. It is intended for an unattended TV-style display in the operations room.
When to Use This Page
Section titled “When to Use This Page”Use the NOC Display when you want a passive overview on a screen people walk past.
| Situation | Page |
|---|---|
| You are actively investigating something | Dashboard |
| You are editing widgets, rearranging layouts | Dashboard (Edit mode) |
| You want one screen to summarise the state of the network at a glance | NOC Display |
| You are mounting an appliance status board in a NOC, command centre, or office | NOC Display |
The Dashboard page has the full toolbar, side menu, and edit affordances. The NOC Display strips those out so the data fills the screen.
Layout
Section titled “Layout”The NOC Display is a single panel: a thin top toolbar and the active dashboard underneath.
+-------------------------------------------------------------+| < o o o o > [Rotate 60s] [Pause] ==== [Kiosk] | <- NOC Toolbar+-------------------------------------------------------------+| || || ACTIVE DASHBOARD (full size) || widgets render edge-to-edge || || |+-------------------------------------------------------------+The toolbar fades down to almost nothing in kiosk mode so the dashboard itself takes the whole screen.
Toolbar Controls
Section titled “Toolbar Controls”From left to right:
- Previous / Next arrows — manually step through your dashboards.
- Dashboard dots — one dot per dashboard, filled for the current one. They double as a position indicator during rotation.
- Rotate — start automatic cycling through your dashboards. When rotation is on, the button shows the interval (for example
60s) and the icon spins slowly. - Pause — appears only while rotating. Pause holds the current dashboard until you resume.
- Progress bar — appears below the rotation button while rotation is active and not paused. It fills up over the interval and resets on each switch.
- Alert indicator — appears in the centre of the toolbar when alert count is elevated, warning, or critical. It is hidden during normal operation.
- Settings cog — opens the NOC Settings modal (rotation interval).
- Kiosk / Exit — enter or leave fullscreen mode.
Rotation
Section titled “Rotation”Rotation cycles automatically through every dashboard on your account, in the order they appear in the side menu.
Press the rotate button to start. The display switches to the next dashboard each time the interval elapses. The progress bar shows time remaining in the current rotation. Press pause to hold on the current dashboard without leaving rotation mode; press it again to resume.
To change the interval, click the cog icon to open NOC Settings. The interval is set in seconds (10 to 600 seconds; the default is 60). The change applies immediately.
Tip. Build a small set of focused NOC dashboards — for example “Service Health”, “Firewall”, “Alarms”, “LLM Activity”. Rotating through four 8-widget dashboards is more useful than displaying one 30-widget dashboard that no-one can read from across the room.
Reordering Dashboards for Rotation
Section titled “Reordering Dashboards for Rotation”The rotation order follows the order of dashboards in the side menu. To change the order, open the dashboard list in the side menu and use the up/down arrows next to each entry — the same controls described in Dashboard (chapter 07).
Kiosk Mode
Section titled “Kiosk Mode”Kiosk mode is fullscreen presentation: the browser goes edge-to-edge, the cursor hides after a moment of inactivity, and the system asks the browser to keep the display awake.
Press the Kiosk button on the toolbar to enter. The page goes fullscreen, the side menu is dismissed, and the toolbar collapses to its minimal form. Press the Exit button (same place as Kiosk) or hit Escape on the keyboard to leave.
Kiosk mode and rotation are independent — you can rotate without kiosk, or kiosk without rotation. The typical NOC pattern is both at once: open the NOC Display, start rotation, then enter kiosk.
Keyboard Shortcuts
Section titled “Keyboard Shortcuts”The NOC Display listens for a small set of keys, designed so an operator can drive the wall display with a numeric keypad remote or a USB clicker.
| Key | Action |
|---|---|
| F11 | Toggle kiosk mode |
| Ctrl + K | Toggle kiosk mode |
| Escape | Exit kiosk mode |
| Left arrow | Previous dashboard |
| Right arrow | Next dashboard |
| Spacebar | Pause / resume rotation (only while rotating) |
Alert Escalation
Section titled “Alert Escalation”The NOC Display draws extra attention to the screen when the alert count rises. It is visual feedback designed for someone glancing across a room.
The escalation system reads the current alert count and maps it to one of four levels:
| Level | When it triggers | Visual effect |
|---|---|---|
| Normal | Alert count below the warning threshold | No badge, no border effect |
| Elevated | Alert count at or above the warning threshold (default 5) | Yellow badge in the toolbar; slow gentle pulse on the page border |
| Warning | Alert count at or above the critical threshold (default 10) | Orange badge; medium pulse |
| Critical | Alert count at or above 2x the critical threshold (default 20) | Red badge, red border, faster pulse |
The thresholds are tuned to be informative rather than annoying — there is no full-screen flash or strobe. A quiet pulse and a coloured edge are enough to draw attention without aggravating people working in the room.
When the alert level changes, the active dashboard does not switch. The widgets keep refreshing on their own schedule. Open Alarms (chapter 11) to investigate what triggered the elevation.
What the NOC Display Shows
Section titled “What the NOC Display Shows”The widgets on the screen come from whichever of your saved dashboards is currently active. The NOC Display does not have its own widget set.
A practical NOC layout typically includes:
- DHCP Service Health Score — single gauge summarising service quality.
- Traffic Flow — the Sankey diagram showing how much traffic the firewall is dropping vs accepting.
- Firing Alarms / Total Alarms — single numbers from the alarm engine.
- High Risk Alerts — LLM-flagged anomalies in the time range.
- Alert Feed — a scrolling real-time feed of anomaly alerts.
- Recent Anomaly Alerts or Top Risky MAC Addresses — table of devices worth investigating.
You can build this list inside an edit-mode dashboard on the Dashboard (chapter 07) page and then point the NOC display at it.
Refresh Cadence
Section titled “Refresh Cadence”Each widget refreshes on its own schedule, controlled from the originating dashboard.
The refresh interval set on the source dashboard’s toolbar continues to apply on the NOC Display — for example “every 30 seconds”. Switching dashboards (manually or via rotation) does not force a refresh; the new dashboard’s widgets render whatever data they last fetched until their next scheduled refresh.
If a widget is showing stale data when you walk up to the screen, opening the source dashboard and pressing the manual refresh button will update both views.
Differences from the Dashboard Page
Section titled “Differences from the Dashboard Page”| Feature | Dashboard | NOC Display |
|---|---|---|
| Toolbar | Full | Minimised; nearly invisible in kiosk |
| Side menu | Visible | Hidden in kiosk |
| Edit mode | Yes | No |
| Add / remove widgets | Yes | No |
| Time range picker | Yes | Inherits from dashboard |
| Refresh interval picker | Yes | Inherits from dashboard |
| Rotation | Yes (same engine) | Yes |
| Kiosk fullscreen | Yes (same engine) | Yes |
| Alert escalation visuals | No | Yes |
| Keyboard navigation | Standard | Arrow keys, spacebar, F11 |
| Intended use | Daily operator work | Wall display |
Both pages share the same dashboards under the hood. Switching between them is just a different presentation layer over the same widget data.
Setting Up a Wall Display
Section titled “Setting Up a Wall Display”A few practical notes for mounting the appliance dashboard on a TV.
- Choose a workstation or thin client with a wired Ethernet connection to the appliance network.
- Open a browser, log in as a dedicated NOC operator account (so the dashboards and rotation order are isolated from any individual operator’s preferences).
- Build or import the dashboards you want in rotation. Set their refresh interval to something reasonable (30 seconds to 1 minute is typical — see Dashboard, chapter 07).
- Navigate to the NOC Display page.
- Click the cog icon, set the rotation interval (for example 60 seconds).
- Press Rotate, then Kiosk.
- Use the operating system’s display sleep settings to keep the screen awake. The browser is asked to hold a wake-lock but a power-management policy at the operating-system level is more reliable.
Tip. Dedicate a separate user account for the wall display. Anyone editing dashboards on their own account does not disturb the wall layout. You can also export dashboards as JSON and import them into the NOC account from the Dashboard page.
Warning. Do not use a personal admin account for the wall display. The NOC station is typically physically accessible — pin it to a viewer-role account with no destructive permissions.
