How to Install nload in Linux?

nload is a console-based application which monitors network traffic and bandwidth usage in real. It provides information about incoming and outgoing traffic using graphs, and additionally it provides information like current data transferring rate average data transferred, and minimum and maximum data transferred by the network. nload provides the facility to monitor more than one network device at a time. Now let’s see how to install nload on Linux system

Installation of nload:

To install nload on Debian based system like Ubuntu, Kali Linux use the following command:

sudo apt install nload 

To install nload On CentOS and RHEL use the following commands

yum install nload

To install nload on Fedora 22+ use the following command

dnf install nload

How to use of nload?

Now we have installed nload on the system, To use nload run the simple command:

nload

Alternatively, you can start the nload by specifying the network devices name like:

nload wlo1

Then you will see the output like

Key Shortcuts

• Left and Right arrow keys or Tab and Enter keys: By using these keys we can switch to other network devices.
• F2 key: To see the option window
• F5 key: To save current settings to the user’s config file.
• F6 key: To reload settings from the config files.

Options to use with nload

# 1: -m option

To see multiple network devices at the same time without graph use -m option. Use arrow keys to go to the next page and the previous page.

nload -m 

#2: -a period option

Use this option to set the length in seconds of the time window for average calculation.  The default is 300.

nload -a 400

#3: -t interval option

Use -t option to determines the refresh interval of the display in milliseconds.  The default value of the interval is 500.

nload -t 400

 Note: Specifying refresh intervals shorter than about 100 milliseconds makes traffic calculation very unprecise.

4) -u h|b|k|m|g  H|B|K|M|G option 

Use -u option to set the type of unit used for display of traffic number.

h/H = auto, b = Bit/s  B = Byte/s  , k = kBit/s   , K = KByte/s , m = MBit/s  , M = MByte/s , g = GBit/s, G = GByte/s

eg:

nload -u M wlo1

Then we can see all output parameters in MBytes/s

 To get more information about the nload use the help command:

nload --help
