Network Performance Monitoring
For early risers it often feels like the most productive time at the office is early in the morning before everybody else arrives. There is a nice quiet calm, no distractions and no interruptions so that focus can be maintained. It even feels like the internet runs faster in the morning before everybody else gets on. In most office there is a considerable difference in computer network speed during high load and low usage times. The reason for this is that most networks are underpowered and are not doing routine performance monitoring.
Performance monitoring can help the network divert critical resources from unimportant functions to more important ones. Image a busy weekday afternoon where everybody in the office is on the network doing work. At the same time that the finance department is performing important financial transactions someone is sending a funny email video to everybody in the office. The video could be a large file which when copied to everybody in the office bogs down the network and stops the financial transactions from going through.
In this scenario intelligent network performance monitoring can assure that network will not crash and that company will not lose money. The performance monitoring can recognize that firstly there is a high volume of traffic and the bandwidth is close to being maximized. Secondly is can identify that the video is a low priority transfer and the financial transaction is a high priority transfer. Network performance monitoring can tell available network hardware, like switches, routers and front-end applications, to divert the necessary resources to complete the financial transaction before the video upload.
performance monitoring can also give good insight into the health of a network and vulnerabilities to denial of service attacks. Radware, a high quality manufacturer of performance monitoring hardware, builds hardware that not only does performance monitoring but also load balancing, and network protection.
The importance of performance monitoring can be seen in more detail here. Ariel R

Network bandwidth usage?
I'm looking for a cheap (read free) network usage monitor that tracks usage per program, not just network card. Thanks!

hello i am a tybsc it student i want some help in my project.....?
my topic is a n/w monitoring system.The proposed project will be very useful to monitor the use of printer, internet and other shared resources in the network. it will be developed in java.Please send me some details about starting it.
details:
The modules of the proposed projects are
1. Printer Monitor: This module will monitor the usage of printer in the antire network. The commands sent to the printer will be displayed in an interface with source IP, User, command, no of pages, size etc.. These details will be logged and the logged details can be analysed using some preset values.
2. Internet Usage Monitor: In this module evrey request will be logged and displayed such as source IP, User, Destination IP/Address, Port, size etc. The band width usage of every user/ip can be extracted separately.
3. Network Usage monitor: This module will monitor the usage of network traffic.
4. User Monitor: This will monitor the user activities in the network such as login, logout etc.
5. Client Monitor: This will monitor the applications running on the client. CPU usage, Memory usage etc. in real time. By verifying this details the network administrator can determine upgrade requirements of client computers.

Programs report Double Bandwidth usage over a VPN?
Any idea why this is happening? Do VPN's actually use double the usage or is this some sort of mistake?
Just left Utorrent to download for a few minutes to get some statistics
What Utorrent reports:
Down: 15.4MB
Up: 0.286MB
I used two network usage monitoring programs Networx and Bitmeter.
What Networx Reports:
Down: 39MB
UP: 3.25MB
What Bitmeter Reports:
Down: 38.94MB
Up: 3.92MB
Statistics from my modem: (I disabled wireless and any other computing accessing the router and reset the statistics before doing this.)
Ethernet
Recieved: 3123159 Bytes (2.97MB)
Transmitted: 22473096 Bytes (21.43MB)
WAN
Recieved: 22420320 (21.38MB)
Transmitted: 3158832 (3.01MB)
Screenshot of modem statistics: http://img263.imageshack.us/img263/6910/modemstatistics.png
What does WAN mean? Should I add Ethernet and Wan up to get a total? Any idea why my modem is reporting that Ethernet has only received 2.97MB and Sent 21.43MB? Shouldn't it be the other way around?
Haha hope someone can help. :)
Thanks
