Using the Interface Overview Dashboard

You use the Interface Overview Dashboard to get a consolidated view of device interfaces and system instances, with real-time and historical performance metrics across various measurement categories. Within the dashboard, you monitor operational health, identify performance bottlenecks, and generate insights for capacity planning and troubleshooting. You do this by first selecting a dashboard tab and then by viewing and interpreting the dashboard panels that highlight key measurements for operations.

When navigating directly to this dashboard, use the filter menus at the top to select a specific interface by name. You can also navigate to this dashboard by clicking on a hyperlinked interface name in one of the other dashboards, like the Device Overview Dashboard.

The following dashboard tabs on this dashboard organize performance data into multiple categories:

Network

You use this tab for detailed visibility into interface-level performance and health, enabling you to identify congestion, packet loss, and interface errors.

This tab includes the following panels:

Status

This panel shows the administrative status and operational status of the interface. The administrative status is the state the interface was configured in. The operational status is the actual operational state of the interface. For both statuses, the values are either Up or Down.

Interface Details

This panel shows metadata for the selected interface, including the interface instance, device name, interface name, description, alias, and status.

Interface Table

This panel displays a table of interfaces and their current performance data. Each row includes the following columns:

Interface Inbound and Outbound Bandwidth

This panel displays inbound and outbound bandwidth trends for the selected interface over time. Bandwidth values are displayed as a rate in bits per second and are automatically scaled, for example, to Mb/s or Gb/s. Use this panel to identify traffic patterns, usage spikes, and saturation points.

Average Inbound Bandwidth Usage

This gauge shows the average inbound bandwidth rate received by the interface for the selected time range. The value is displayed in bits per second and is automatically scaled, for example, to Mb/s or Gb/s.

Average Outbound Bandwidth Usage

This gauge shows the average outbound bandwidth rate transmitted by the interface for the selected time range. The value is displayed in bits per second and is automatically scaled, for example, to Mb/s or Gb/s.

Packet Discards

This panel displays the number of packets discarded by the interface over time. Use it to identify persistent or intermittent interface issues that may impact network reliability.

Packet Errors

This panel displays the number of packet errors detected by the interface over time. Use it to identify persistent or intermittent interface issues that may impact network reliability.

CPU Utilization

You use this tab to monitor processing load across device instances and check if system performance remains within acceptable thresholds.

This tab includes the following panels:

CPU Instances

This panel consists of a table that lists the CPU instances for the selected device. The table includes the following columns:

CPU Utilization

This panel displays device CPU utilization trends over time. Use it to identify sustained loads or abnormal spikes.

Current CPU Utilization (%)

This panel displays current CPU utilization. Use it for quick status assessments.

Instance List

This panel shows a table containing all instances of the selected device and selected metrics for each instance. The table includes the following columns:

Memory Usage

You use this tab to identify memory consumption patterns across instances and support proactive resource management.

This tab includes the following panels:

Memory Usage Metrics

This panel consists of a table that shows memory-usage metrics for each instance. The table includes the following columns:

Memory Usage

This panel displays memory utilization over time at the device level. Use it to identify sustained loads or abnormal spikes.

Current Memory Utilization

This panel displays current memory utilization. Use it for quick status assessments.

Instance List

This panel shows a table containing all instances of the selected device and selected metrics for each instance. The table includes the following columns:

System

You use this tab to view high-level operational statistics reflecting overall device stability and usage.

This tab includes the following panels:

System Instances

This panel consists of a table that shows system metrics for each instance. The table includes the following columns:

Users

This panel displays the number of users over time.

Uptime

This panel displays system uptime over time.

Processes

This panel displays the number of processes over time.

Instance List

This panel shows a table containing all instances of the selected device and selected metrics for each instance. The table includes the following columns:

Disk Usage

You use this tab to track storage consumption and availability, which can help prevent outages due to disk exhaustion.

This tab includes the following panels:

Disk Usage Metrics

This panel consists of a table that shows disk-usage metrics for each instance. The table includes the following columns:

Disk Usage

This panel displays disk utilization trends over time. Use it to identify sustained loads or abnormal spikes.

Current Disk Utilization

This panel displays current disk utilization. Use it for quick status assessments.

Instance List

This panel shows a table containing all instances of the selected device and selected metrics for each instance. The table includes the following columns:
