Network Monitoring Tools

Hi, i want to know which software is good for monitoring all network resourses like Traffic, CPU, Memory & Disk space utilization/server, others...
I already googled for these softwares but also I need your comments.
I dont mind if it is freeware or no, i want to know what are my options.

Thanks

Check out the GFI product suite
Or there is NetIQ for extensive monitoring of server vital signs
Or you could use MRTG or PRTG to monitor all sorts of things including disk space and CPU via the SNMP counters (presuming you enable them all on your machines)
Or you could go for a solution such as Openview
All depends on what your budget is and what you actually want...

Another good one i have used it Solarwinds Orion. Its relatively simple to setup and quite powerful.

What's Up Gold (Windows) can use SNMP traps and WMI.

Open source solutions such as Nagios and Zenoss work well too.

I'm too thumbs-up for GFI's Network Server Monitor product - it's an excellent product with all the necessary features you require, plus a great GUI Interface to ensure you get all the required information on your screen.

yeah chris i have all thumbs too for GFI NSM...its cool.
