Aggregate Performance

The Aggregate Performance report runs an aggregation function on selected attributes of monitor instances belonging to the specified group, over a specified time period. The aggregation function can be Average, Sum, Maximum, Minimum, Median, Percentile, and Standard Deviation. The result of aggregation is displayed as multiple summary line graphs (stacked line graphs). Each graph reflects the aggregation result of attributes that have the same unit of measurement.

If Table Display is enabled, the report is displayed in tab format, where the first tab consists of all the line graphs and the second tab shows a complete list of all instances of the selected group in table format along with the minimum, average, and maximum values for the specified attribute. Drill down from any of the instances to view the corresponding independent line graph for that instance.

Individual graphs for each instance or attribute are displayed (for the selected report period) when the Show graphs for each Instance or Attribute option is selected. The summary graph is larger than the individual graphs.

Aggregate Performance reports can be made using multiple subreports, where each sub-report is a combination of different group-attribute-set and aggregate functions. If the Show detail table option is enabled for such reports, the first tab displays graphs corresponding to each subreport, and the second tab displays different tables corresponding to each graph.

The following default reports of the Aggregate Performance type are provided out-of-the-box by Infrastructure Management:

  • Web Transaction Availability and Response Time - a weekly aggregation of data with the following subreports:
    • Transaction Availability 
    • Transaction Response Time 
  • Server Capacity - a weekly aggregation of data with the following subreports:
    • Server CPU Capacity (includes subreports) 
    • Server Memory Capacity

The following table lists attributes specific to the Aggregate Performance report that needs to be entered along with common attributes.

Aggregate Performance report attributes 

Attributes

Description

Select Group

Select a group to display monitors based on the group selected. For more information, see Common report attributes.

Select Attributes

Select Attributes (to be part of the subreport) from Available attributes and transfer to Selected Attributes. Use the Ctrl andShift keys to make multiple selections. Alternatively, use the search box to locate a specific attribute.

Select Aggregate Function

  • Avg - (Average) Sum of all data points for each instance-attribute and divided by the total number of instances
  • Sum - all data points for each instance-attribute
  • Min - (Minimum) Sort the data points from the various instances and take the lowest value
  • Max - (Maximum) - Sort the data points from the various instances and take the highest value
  • Median - Sort the data points from the various instances and take the middle value
  • Percentile - Value that X% of the monitors and below are reporting. (0 being the minimum, 100 being the maximum, and 50 being the median) If percentile is selected, then the Weightage box is enabled for the user to select the appropriate nth weightage factor.
  • Standard Deviation - It is the standard deviation across all the underlying instances.

Sub Report Title

Enter the title for subreport. For more information, see Common report attributes.

Graph Title

Enter title for graph.

Add Sub Report

Append subreports to the Added Sub Report section. For more information, see Common report attributes.

Show Tables in separate Tab

Select this option to view tables in separate tabs.

Hide Attribute Column Name

Select this option to hide the attribute column from being displayed in the report. This option is enabled only when the Show Tables in separate Tab option is selected.

Show Graphs for each Instance/Attribute

Select this option to display individual graphs for each instance or attribute for the selected report period.

The report display can get distorted in the following scenarios:

  • When the report is viewed using IE 5.5 
  • When the report has too much data

Note

If the report size appears to be small, add the following properties in the installationDirectory\pw\pronto\conf\pronet.conf file:

pronet.report.aggregate.instance.height=100

pronet.report.aggregate.motype.height=125
