Resource utilization for each managed instance of sQL server is presented in the list view located at the top of the Utility explorer content pane. Health state icons appear to the right of each managed instance and provide summary status for each instance of sQL server based on the utilization category. three icons are used to indicate the health of each managed instance of sQL server. a green check mark indicates that an instance is well utilized and does not violate any policies. a red arrow indicates that an instance is overutilized, and a green arrow indicates underutilization. the lower half of the dashboard contains tabs for cPU utilization, storage utilization, policy details, and property details for each managed instance. In Figure 5-7, the instance CPU, computer CPU, ile space, and volume space columns for sQL2K8R2-01\instance01 and sQL2K8R2-01\instance05 are all underutilized. in addition, the following other elements are underutilized: the instance cPU for sQL2K8R2-03\ instance03, computer cPU for sQL2K8R2-01\instance02, sQL2K8R2-01\instance03, sQL2K8R2-01\instance04 and sQL2K8R2-01\instance05, File space for sQL2K8R2-02\instance03 and Volume space for sQL2K8R2-01\instance02, sQL2K8R2-01\instance03, and sQL2K8R2-01\instance04. the volume space for sQL2K8R2-02, sQL2K8R2-02\instance02, sQL2K8R2-03, sQL2K8R2-03\instance02, sQL2K8R2-03\instance03, and sQL2K8R2-03\ instance04 are all overutilized, and the remainder of managed instances are well utilized. the Managed instances list view columns and utilization tabs are discussed in more detail in the next sections.
The Managed Instances List View Columns the health status of each managed instance of sQL server in the Managed instances list view is analyzed against four types of utilization and the current policy in place for each: â–
Instance CPU this column indicates processor utilization of the managed instance. the health state is determined by the global cPU Utilization For all Managed instances of sQL server policy, which is predetermined for all managed instances of sQL server. However, by clicking on the Policy tab in the bottom half of the view, DBas can override this global policy to conigure overutilization and underutilization policies for a single instance. the cPU Utilization tab shows the cPU utilization history for the selected managed instance of sQL server.

Computer CPU this column communicates computer processor utilization where the managed instance resides. Health is based on the settings of two policies: the cPU utilization policy in place for the computer and the coniguration setting for the Volatile Resource evaluation policy. the cPU Utilization tab shows the processor utilization history for a managed instance of sQL server. File Space The File Space column summarizes ile space utilization for all of the databases belonging to a selected instance of sQL server. the health state for this parameter is determined by global or local ile space utilization policies. Because there are many database associated with a managed instance of sQL server, the health state is reported as overutilized if only one database is overutilized. the storage Utilization tab shows health state information on all other database iles.
