Basic Usage and Configuration

Getting Started with Nload

Launch nload with the simple command:

nload

The application automatically detects available network interfaces and begins monitoring the first active interface. The default display shows two graphs: incoming traffic (Incoming) on top and outgoing traffic (Outgoing) below. Current transfer rates appear alongside each graph, along with average rates calculated over the configured time window.

Graph interpretation requires understanding the scale indicators and measurement units. The horizontal axis represents time progression, while vertical scaling adjusts automatically based on traffic volume. Peak values and current rates are clearly labeled, enabling quick assessment of network utilization patterns.

Statistical information includes current transfer rates, average calculations over specified time periods, and minimum/maximum values observed during the monitoring session. These metrics provide comprehensive insight into network behavior patterns and help identify both peak usage periods and baseline activity levels.

Interface-Specific Monitoring

Monitor specific network interfaces by specifying the interface name:

nload eth0

Common interface naming conventions in Ubuntu 24.04 include predictable network interface names such as:

• enp0s3 for Ethernet interfaces
• wlp2s0 for wireless interfaces
• lo for loopback interface

List available interfaces using:

ip link show

Switch between multiple interfaces during runtime using left and right arrow keys when nload is running. This navigation capability enables monitoring of complex network configurations without restarting the application.

Real-world scenarios for interface-specific monitoring include troubleshooting specific connection problems, monitoring wireless versus wired traffic patterns, and analyzing traffic distribution across multiple network adapters in server environments.

Command-Line Options and Parameters

Display multiple devices simultaneously using the multi-device view:

nload -m

This option shows traffic statistics for all detected interfaces without displaying graphs, providing a comprehensive overview of system-wide network activity.

Configure the time window for average calculations:

nload -a 600

The -a parameter sets the averaging period in seconds, defaulting to 300 seconds. Longer periods provide more stable averages but respond more slowly to traffic changes.

Adjust refresh intervals using the -t option:

nload -t 1000

This parameter controls display update frequency in milliseconds, with 500 milliseconds as the default. Shorter intervals provide more responsive displays but may impact system performance and calculation accuracy.

Customize measurement units with -u and -U options:

nload -u M -U G

Unit options include:

• h: automatic scaling
• b: bits per second
• k: kilobits per second
• m: megabits per second
• B: bytes per second
• K: kilobytes per second
• M: megabytes per second
