I'm currently looking for network monitoring off our production network uplink but it runs on fiber optics cable. My peek throughput is around 150mb/s to 200mb/s. Can Netprobe handle that amount of traffic and what kind of hardware I'm looking into in order to support it.

Thanks

Derek

Also, which linux would be recommended to run the netprobe on? Redhat 9.0/Fedora 1,2,3/FreeBSD 5.2,5.3?

Network Probe should be able to handle approximately 70-100.000 packets per second. To do some memory/performance tests, start it from command line with the "-loadtest" parameter, and give us the results. As long as the traffic is not very diversified, it should run very well without memory problems.

I recommend at least a 2 GHz CPU with 1 GB of RAM. We've done successfully tests on both RedHat, Fedora and FreeBSD on medium scaled networks, but it does not matter which distribution you choose (but from my personal point of view I would recommend Fedora Core with a 2.6 kernel).

Network Probe is primarly used to monitor traffic between local segments and the Internet. Your WAN is not very likely using over 150-200 Mbit/s, so Network Probe should work very well for that purpose.

Does Network probe works better on Linux system compare to windows 2003 because less overhead on OS? Is the same hardware requirement applies to Windows platform?

Expect a slightly less CPU usage on Linux systems. However, I recommend using the client from a remote, Windows system. Java applets generally have better performance under Windows.
