Free performance monitoring software software for windows

Performance Monitor - Performance Monitor is a program that shows you the CPU, Memory, Disk and Network utilization under Windows NT platforms (2000, XP+). Its composed by four fully configurable small graphs and it can work in the tray area also. The windows are fully anchorable and by moving the "CPU" window youll move the other attached windows. PerfMon can become transparent and permits you to forward left-mouse clicks so you can place it anywhere. You can also change the program priority saving CPU work and double its size for big monitor resolutions ;-)

Removed the flickering effect from the ToolTip,Added the "Invisible mode" option, Fixed a bug that in some computers prevents PerfMon to work correctly, Changed the tray icons management

Checks performance counters, line or pile graph, ability to choose a network interface, lighter than before

PA Server Monitor has powerful features that are very simple to setup. The Free edition monitors web pages, ping response and the Windows event log, and response actions that can send SMTP email notifications, reboot the server, and more. Reports can be generated about most monitored resources.
And, our product is smart. Theres nothing like our Easy Configuration system for quickly setting up multiple computers, or our smart email alerts that bundle alerts together to keep from overwhelming your inbox. Our smart alerting will tell you about a particular problem once, and then tell you when it is fixed (instead of the constant stream of mindless still broke messages that other products send).
