MRTG can interface with any WMI counter logs and the results can be put in a web page such as
this one on my home workstation.
You can also configure Performance Monitor Alerts to send messages when a monitored counter is outside the specified values.
Performance Monitor is part of Windows. Run PerfMon.msc.
MRTG can be obtained at
