In Operations Manager 2007, a self-tuning threshold monitor uses a learning process to determine the normal values for a specified performance counter object and sets the threshold levels based on the learned values. You can use the Create a Unit Monitor Wizard to create a self-tuning threshold monitor, which you can open by clicking Create a monitor in the Actions pane of the Authoring area and then selecting Windows Performance Counter under Select the type of monitor to create.

Self-tuning monitors cannot be used with multiple instance performance counters. Any counter that is configured with the All instances option selected cannot be learned by Operations Manager 2007.

Self-tuning monitors require a learning period, during which time Operations Manager 2007 automatically establishes a baseline that represents the regular and expected activity of a computer. The established baseline accurately reflects your organization's use of the IT infrastructure by taking into account patterns and variations in usage—for example, increased processor utilization on Monday mornings at 9:00 A.M.

After the initial learning period, Operations Manager 2007 continually logs subsequent activity of the computer and compares it to the baseline. The state of the monitor changes only when the performance counter exceeds the boundaries of the baseline. Using a performance baseline monitor can result in more accurate reporting of counters that vary during a business cycle.

Self-tuning monitors are divided into the following categories:
