Performance Details Report Knowledge

更新日期: 2009年8月

適用於: Operations Manager 2007 R2

This Performance Details report shows selected objects and performance counter values graphically over time.

Description

This report shows a series with these fixed settings:

  • Average is shown as a black line.

  • Standard deviation is shown as an orange area.

  • The area between the lowest and highest values is filled with blue.

If a histogram is specified, this report displays a link to a table detailing average, minimum, maximum, and standard deviation for all time periods averaged into one x-axis unit. A second, smaller chart details the number of performance counter samples making up this report.

Parameters

 

Parameter Description

Data Aggregation

Report can be run using the hourly or daily aggregations of data.

Date/Time Selection

Defines a time period for the report with relative or fixed dates.

Business hours

Defines a business hours time range and the weekdays it applies to. If business hours are defined, this report only reports within this range. Business hours only works if hourly aggregation is selected.

Object Picker

Enables you to choose which groups or objects to show alerts for.

When using the object picker, selecting Add Group will return the group and all objects it contains. Add Object returns only the selected object.

Histogram

Specifies the values to use for the x-axis of the report.

3D Chart

Specifies whether the report is shown in a flat or a 3D image.

note附註
Most performance counters are targeted at the Windows operating system, so when you use the Object Picker, select an object of class Windows Operating System. If you select Windows Computer, performance information will only be shown if you use Add Group.

Sample Usage

You can run the following reports.

  • Learn about historical capacity needs. Use this report to display performance data indicating capacity usage (such as free disk space) This report, when run over six months worth of data, shows the development of the capacity needs if the parameter Histogram = "No" is chosen.

  • Understand load. Use this report to display performance data that indicates user load.With a histogram of "Daily by hours," the report shows what load is to be expected (the standard deviation in orange) and could be happening (the minimum to maximum values in blue) at which time of the day.

  • Understand the average and drill to the details. This report allows adding more than one object to a chart series for a single performance data item. For example, you can add all servers hosting the SAP database to a % free database space for the SAP database. In the rendered report, there is a link in the Actions menu to break out the series per object (for example, to review charts for each individual server).
