Dynamic graphs and real-time statistics that show the activity on your various network interfaces can give you a great heads-up on your network's performance and bandwidth consumption. This is exactly what bmon provides for you , right in a terminal window.

From: Brian May Prev by Date: Re: hurd does NOT need /hurd; Next by Date: Re: Bandwidth monitoring GNOME System Monitor is a GNOME process viewer and system monitor with an attractive, easy-to-use interface, It has features, such as a tree view for process dependencies, icons for processes, the ability to hide processes that you don't want to see, graphical time histories of CPU/memory/swap usage, the ability to kill/renice processes needing root access, as well as the standard features Bandwidth in computer networking refers to the data rate supported by a network connection or interface. One most commonly expresses bandwidth in terms of bits per second (bps). The term comes from the field of electrical engineering, where bandwidth represents the total distance or range between the highest and lowest signals on the communication channel (band). Keeping control of our network is vital to prevent any program from overusing it and slows down the overall system operation. There are several network monitoring tools for different operating systems today. In this article, we will talk about 10 network monitoring tools for Linux that will run from a terminal, ideal for users who do not use GUI or for those who want to keep control of the This describes a Debian install of Bandwidth to monitor network activity on your LAN. There apparently is also a binary build you can run on Windows now. I have not used it, and do not know exactly how it works, I may download it and write a how-to for that as well. But for now this is a Linux only How-To. For disk I/O trending there are a few options. My personal favorite is the sar command from sysstat.By default, it gives output like this: 09:25:01 AM CPU %user %nice %system %iowait %steal %idle 09:35:01 AM all 0.11 0.00 0.01 0.00 0.00 99.88 09:45:01 AM all 0.12 0.00 0.01 0.00 0.00 99.86 09:55:01 AM all 0.09 0.00 0.01 0.00 0.00 99.90 10:05:01 AM all 0.10 0.00 0.01 0.02 0.01 99.86 Average: all Solarwinds offers a FREE Real-Time monitoring utility to track network usage/bandwidth within your network by interface. Easy to setup and manage using SNMP, Solarwinds' offering is amongst the best in terms of viewing inbound/outbound traffic on an interface level of any system setup with SNMP within your network.

Here are some nice tools in the Ubuntu repositories for command line network traffic monitoring: bmon - shows multiple interfaces at once. slurm - has nice colored graphs. tcptrack - A favorite. Tells how much bandwidth is being used and also what protocol (service/port) and destination the transmission is taking place to. NetHogs Linux Bandwidth Monitoring. Read More: Monitor Linux Network Bandwidth Using NetHogs. 13. iftop - Network Bandwidth Monitoring. iftop is another terminal-based free open source system monitoring utility that displays a frequently updated list of network bandwidth utilization (source and destination hosts) that passing through the network interface on your system. iftop is considered Debian Network Tools For Administrators. We are going to see some of the network monitoring and network traffic related tools available in Debian. BWM - BandWidth Monitor This is a very tiny bandwidth monitor (not X11). Can monitor up to 16 interfaces in the in the same time, and shows totals too. Installing BWM in debian #apt-get install bwm IPTraf is an open-source command-line network monitoring tool that allows monitoring of various network statistics such as TCP, UDP, Ethernet load, ICMP, etc. We can use it to view network usage of a processes running in Linux. Installation. IPTraf is included in the official repositories of the Ubuntu system.

Bandwidth usage tracking can be used to avoid both issues or help catch usage problem before it gets out of hand (expensive). There is a Cloud Control bandwidth monitor that you can consult, but it requires logging into your cloud control portal and your specific instance. vnstat, on the other hand, is local to your Server, and when combined
