A baseline is a set of data that indicates how system resources are being used. You can then compare this data with later activity to help determine system usage and system response to that usage.
To create a standard Windows baseline, you should monitor resources from the four major server resources:
Using PATROL, you should consider monitoring the parameters listed below.
Capture and save the history data from these parameters to find out what is normal for your system. You can use this data to find performance bottlenecks and to analyze future trends for capacity planning. The PATROL History Loader product can help you manage PATROL history data and port it to the database management system of your choice.
