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.

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
Status	Displays the interface status as a list

For equipment without physical port information, the message There is no collected interface port information. is displayed instead of the frame, and the entry point for the port layout settings is not exposed either.

Port layout settings

In the Device format, you can adjust the port layout displayed on the screen to match the actual equipment.

1. Click the icon. The Port Layout Settings window opens.

2. Select the equipment specification in the Frame area.

   Item	Description
   Width	Number of ports one row holds. 24 ports or 48 ports
   Height	Number of frame rows. 1 to 3
   SFP port	Adds 4 extra port slots on the right of each row

3. Drag a port, or click a port and then click the position to move it to, to change its location.

4. Click the Apply button to save. To revert, click the Cancel button.

   • To return to the default layout, click the Restore default layout button.

Note

If the frame capacity is insufficient, the message {count} ports are left outside the frame. Increase the width or height. is displayed. When all ports are placed, the number of placed ports and remaining slots is displayed.

Note

In the Status format, or when there are no physical ports to edit, the port layout settings button is displayed as disabled and the reason is shown in a tooltip.

Usage Status - Device

When a device is selected, the overall interface traffic trends for that device are displayed in a line chart.

Chart panels

Panel	Description
Total Throughput	Total throughput of all interfaces combined, displayed across the full width of the screen
Inbound Throughput	Inbound traffic per interface, with each interface displayed as a separate line
Outbound Throughput	Outbound traffic per interface
Top N (Daily)	Interface ranking table based on maximum daily throughput
Top N (10 min)	Interface ranking table based on maximum throughput in the last 10 minutes

Top N table columns

Column	Description
Interface	Interface name
Today / Recent 10 Min	Maximum throughput (in bps) for the period
Current	Current throughput (in bps)

Note

The Top N table is sorted in descending order by throughput, allowing you to quickly identify interfaces with the highest traffic.

Private MIB widget

If a custom OID (Private MIB) is configured for the device, an additional widget is displayed.

Item	Description
Display condition	When OIDs other than AllInterfaces are configured
Widget content	Custom metric charts by OID

Private MIB chart customization

Click the icon at the top right of the Private MIB widget to open the Chart Setting window. The Chart Setting window consists of three areas.

Area	Description
Chart Preview	Preview of how the chart appears with the current settings
OID Information	Detailed information about the OID
	OID: Target OID to collect (for example, 1.3.6.1.4.1.9.6.1.101.1.8.0) MIB Info: MIB module and symbol information (for example, CISCOSB-MIB::rlCpuUtilDuringLastMinute) Node Type: MIB node type (for example, Integer32, Counter64) Description: OID description defined in the MIB file
Chart Setting	Setting options such as chart type and unit

Chart Setting options

Set the Chart Setting options: Time Range, Chart Type, and Unit.

Time Range

Option	Description	Available charts
Recent 30 Min	Displays the last 30 minutes of data as a time series	Line, Bar
Latest	Displays only the most recent value	Text, Table

Note

When you change the Time Range, the available Chart Types change automatically.

When Time Range is Recent 30 Min	Line	Time series line chart. Suitable for trend analysis
	Bar	Time series bar chart. Suitable for comparison by interval
When Time Range is Latest	Text	Displays the latest value as large text. Suitable for monitoring a single metric
	Table	Displays the values in a table. Suitable for comparing multiple index values

Unit

Unit	Description	Usage example
Count	Plain number (default)	Number of packets, number of sessions
Byte	Automatic conversion in byte units (KB, MB, GB)	Memory usage, file size
Bit	Automatic conversion in bit units (Kb, Mb, Gb)	Storage capacity

When you select Severity as the Unit, you can map numeric values to meaningful status labels.

Default Severity settings

Value	Label
0	Normal
1	Warning
2	Critical

How to set Severity

1. Select Severity from the Unit dropdown.
