Can monitor up to 16 interfaces in the in the same time, and shows totals too. This is a very tiny bandwidth monitor (not X11). A number of people have asked for the modified program and its source, so I have created this page. The original program was released under the GPL. Peter Anvin, and I (Brian Towne) modified it somewhat to better suit my needs.
Bwbarīwbar is a small C-based program for Linux-based machines which produces bandwidth usage statistics for a network interface.
Various output modes exist including an interactive curses interface,lightweight HTML output but also formatable ASCII output. It supports various input methods for different architectures. HTTP, TCP, UDP, ICMP, VPN, and P2P traffic are color coded.īmon is a portable bandwidth monitor and rate estimator running on various operating systems. Furthermore, each ip address’s utilization can be logged out at intervals of 3.3 minutes, 10 minutes, 1 hour or 12 hours in cdf format, or to a backend database server. Charts are built by individual IPs, and by default display utilization over 2 day, 8 day, 40 day, and 400 day periods. BandwidthdīandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization.
The greater the capacity, the more likely that greater performance will follow, though overall performance also depends on other factors, such as latency. 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).īandwidth represents the capacity of the connection. One most commonly expresses bandwidth in terms of bits per second (bps). Bandwidth in computer networking refers to the data rate supported by a network connection or interface.
