How to monitor network performance

[Akul]

Which is the best way to monitor the network performance? I don't know much about this, but i know various tools are available to monitor our network performance . Which is the best tool which gives most accurate statics of network connection bandwidth ? What you use?

Have you checked the Networking tab in Task Manager?

The Networking tab provides an indication of the network traffic for the connections on the local computer. It is useful as a quick reference for determining the amount of network bandwidth being consumed. When multiple network connections are being used, it allows easy comparison of the traffic for each connection.

If you have multiple networking cards on your computer, the chart displays a composite index of all networks, representing all network traffic.

In order to show a visible line on the graph for network traffic on any interface, the view automatically scales to magnify the view of traffic versus available bandwidth. So in a low traffic situation, the full height of the graph may represent only 5% of available bandwidth for the connection. When traffic increases beyond that level, the scaling will be reduced to give a less magnified view of the current traffic (for example, to display 10% of the total available bandwidth). The greater the percentage shown on the graph, the less is the magnification of traffic with respect to available bandwidth. The scaling factor is indicated on the graph. To disable scaling, on the Options menu, click Auto Scale to toggle the value.

I also don't like the task manager ,you should consider NetLimiter, it is great for that and it also allows you to limit bandwidth usage so that you can test your applications in reduced bandwidth scenarios.

There are plenty of network monitoring tools are available, just search on google my friend. WMI monitoring should get most of it. You should be able to get the rest via a windows script monitor. And APM also one of the best tool.
