Network: Monitor Outgoing Bandwidth Latency / Jitter

There are several tools you can use to monitor outgoing bandwidth, latency, and jitter on a Unix or Linux system. Some of the most commonly used tools include:

1. ping: The ping command is a simple utility that sends ICMP echo requests to a remote host and measures the time it takes for the host to respond. ping can be used to measure the latency and jitter of a network connection.

Here’s an example of how to use ping:

The -c option specifies the number of echo requests to send (in this case, 10). Replace remote-host with the hostname or IP address of the remote host you want to measure the latency and jitter of.

2. traceroute: The traceroute command is a utility that traces the route of packets from your system to a remote host. traceroute can be used to measure the latency of a network connection.

Here’s an example of how to use traceroute:

Replace remote-host with the hostname or IP address of the remote host you want to measure the latency of.

3. iperf: The iperf command is a tool that can be used to measure network performance, including bandwidth, latency, and jitter. iperf requires both a client and a server to be run.

Here’s an example of how to use iperf:

Replace remote-host with the hostname or IP address of the iperf server.

4. bwm-ng: The bwm-ng command is a bandwidth monitor that provides real-time statistics about network usage.

Here’s an example of how to use bwm-ng:

The -o plain option specifies that the output should be in plain text format, the -t 1000 option specifies the update interval (in milliseconds), the -T rate option specifies that the output should be in rate format (i.e., bits or bytes per second), and the -u bits option specifies that the output should be in bits.
