Capacity Trends

The Capacity Trends report lists all monitor instances-attribute pairs that are predicted to violate event thresholds in the specified time period. The report contains a bar graph at the top that shows each instance-attribute pair predicted to violate event threshold in the specified time period. The maximum number of bars can be specified during report creation.
 The report displays bar graphs as follows:

  • The instance-attribute pair is displayed on the Y axis. 
  • The duration to violation (in days) is displayed on the X axis. 
  • The table is sorted on instances that are predicted to violate earliest (in case any violated instances are present, they would appear first). 
  • Drilling down on the monitor instance in the table displays a line graph for the selected attribute along with the threshold line.

The report displays line graphs as follows:

  • The line graph is projected using a dotted line from the last data point to the threshold line, and the intersection point is at the predicted violation time. 
  • A dotted line from the intersection point to the X axis is also present.

The following table lists the attributes of the Capacity Trend default report.

Capacity Trend report attributes

Report type

Descriptions

Subreport section

No Filter

Select this option to consider all the instances in the system.

Selected Groups

Select this option to select the attribute groups from the Available Groups box and transfer to the Selected Groups box.

Report Attributes

Single Attribute

Use this filter to report only those events that are associated with the attribute being considered. For more information, see Common report attributes.

Attribute Set

Select an attribute set from the list to limit the report to those attributes present in the attribute set. For more information, seeCommon report attributes.

Consider Sub Transactions if any

Select this option for the report to be generated considering dynamic attributes associated with the monitors of the Attribute set.

Hide Attribute name Column

Select this option for the attribute column not to be listed with the report.

Use Event Thresholds as Capacity Limit

Select this option to use Event capacity as threshold. Highest Severity, Critical, Major, Minor, or All event thresholds can be selected. 
When All or highest severity threshold type is selected, then severity column is displayed and a table title is added, displaying severity of each instance. 
When Critical, Major, or Minor event thresholds are selected, then severity column is hidden, and a table title is added displaying severity type of each instance.

Use Custom Group Threshold

Select this option to set custom group thresholds. This can be used only when the Groups filter is selected. Select the respective groups and click New to set new thresholds. Custom group thresholds can be set for either a single attribute or a group, or multiple attributes or groups.

Schedule

The period corresponding to which the data considered for Report generation. For more information, see Common report attributes.

Sub Report Title

Enter the title of the subreports. For more information, see Common report attributes.

Report Options

  • Data to be used - Specifies whether condensed (rate) or raw (granular) data is to be used. By default, condensed data is selected. Avg, High, or Low rate values can be calculated and applied for only condensed data.
  • Show instance which violates in the next - This is the forecast period. Any instance that is predicted to violate event thresholds in this time period appears in the report. Any violations outside this forecast period is not considered. Default is seven days.
  • Use Data for the last - This option governs the data points to be used for forecasting. Default value is 14 days.
  • Maximum number of bars in graph - Specifies the maximum number of bars to be displayed in the bar graph. Maximum number of bars cannot exceed 20. Default value is 20.
