Device Trend

Home > Select Project > Device Status > Usage Status

In Usage Status, you can check the data related to the device status change in real time. It provides visual metrics for devices and interfaces, allowing you to immediately identify changes in the network performance.

Basic screen and settings

1. In the top option bar Time selection, select the query time point. It displays the most recent 10 minutes of data based on the selected time.

2. In the top option bar Select Manager, select the NMS manager that collects data to check the usage status.

3. In the Device selection area, select the device or specific interface to analyze.

   Selection	View displayed
   Device only	Device level view (all interface trends)
   Device > Interface	Interface level view (single interface details)

4. Check the usage status of the selected device or interface.

Summary and Interface Info tabs

When you select a device, the Summary tab and the Interface Info tab appear in the details area on the right.

Item	Description
Summary tab	Device dashboard made up of widgets. You can move, resize, or hide widgets
Interface Info tab	Interface list table. Click a row to go to that interface's details

The Summary tab consists of fixed widgets that are always shown and one widget for each item registered to the device.

Table | Summary tab widgets

Item	Description
Device visualization	Device name, port layout, and switching the interface display format
Interface status card	Number of Total, Link Up, Link Down, and Admin Down interfaces
Peak Throughput card	Interface with the highest throughput
Throughput chart	Total Throughput, Inbound Throughput, Outbound Throughput
Top N table	Interfaces ranked by maximum throughput, daily and for the last 10 minutes
OID widget	One per OID registered in the device's SNMP Polling. An OID tag appears before the title
Calculated Metric widget	One per calculated metric created for the device. A Calc tag appears before the title

• Fixed widgets can be moved and resized but not hidden.

• Even if the interface traffic (AllInterfaces) OID is not registered for the device, throughput widgets keep their place and show a registration guide inside the widget.

• Hiding a widget does not stop data collection. The widget is only removed from the screen.

Widget management

The widget layout of the Summary tab is saved per device, and all users in the same project see the same layout. Changing the layout requires the project edit role. Without it, you cannot move or hide widgets; you can only register OIDs, add calculated metrics, and change the chart display type.

Editing directly on the screen

1. Drag a widget to move it, or drag its corner to resize it.

2. To hide a widget, click the icon at the top right of the widget and select Hide from screen. Right-clicking the widget opens the same menu.

   • Selecting Change display type in the same menu opens the Chart Setting window.

3. Click the Save layout button that appears with the Not saved indicator next to the device name at the top of the screen. To return to the previous state, click the Revert layout button.

• If you select another device or move to the Interface Info tab without saving, a window asks whether to discard your changes.

• If another user saved the layout of the same device first, the message Another user changed the layout. appears. Click the View new layout button to load the latest layout. If you save in this state, a window asks whether to overwrite it.

Using the widget management window

Click the Manage widgets button at the top right of the Summary tab. Right-clicking an empty area without widgets also opens the widget management window.

Item	Description
Layout	Scaled-down editing area of the Summary tab. Drag widgets to move or resize them, or click × on a box to hide it
List	Registered items, split into the OID and Calculated Metric tabs. Provides a status filter (All, Shown, Hidden) and search
Show on screen switch	Turn off to hide, turn on to show again. A widget shown again is added to the bottom of the layout
Unregister button	Unregisters the OID from the device or deletes the calculated metric

1. Change the widget layout and visibility in the Layout area and the list. Changed items are marked Not applied, and the number of unapplied changes appears at the bottom.

2. Click the Apply button. The changes are applied to the Summary tab and saved immediately. To return to the state before editing, click the Revert button.

   • Clicking the Reset layout button returns to the default layout with no hidden widgets. This change is also saved only when you click Apply.

Adding items

• On the OID tab, click Add OID to select an OID from the OID catalog and register it to the device. You can create an OID that is not in the catalog on the same screen.

• On the Calculated Metric tab, click Add Calculated Metric to create a calculated metric for the current device.

• Added items are registered immediately, regardless of the Apply button, and appear as widgets at the bottom of the layout.

Caution

Unregister cannot be undone. If you register the same OID again, its previous position and hidden state are not restored. An OID used in a formula of the device's calculated metric cannot be unregistered, and the affected calculated metrics are listed.

Interface display format

When you select a device, you can choose the interface display format.

Item	Description
Device	Arranges and displays the ports in the same layout as the front panel of the actual equipment
