A calendar defines specific times and days for monitoring and capturing alarm history. Define a general calendar that captures data using the same days and times every month of the year, or define a more specific calendar that restricts data capture to specific months or days of the year.
Calendars consist of one or more time definitions. Each time definition specifies the days and time intervals for capturing data. You can define new time intervals for a calendar or copy existing ones from other calendars.
The Create Calendar dialog box contains a two-month calendar navigator (in the top right corner of the dialog box) for quick browsing and viewing of the scheduled data capture times for a specific date, as shown by colored blocks in the
section directly below the calendar navigator:Figure 13-2 Calendar Properties
The following sections explain how to create, configure, and maintain calendars:
You can create calendars to associate with profiles used to select elements for which performance and alarm data is collected. For more information on profiles, see Section 12.2, Using Profiles and Expressions to Capture Alarm History.
To create a calendar:
In the
pane, expand > .Right-click the
element, then select to open the Create Calendar dialog box.Enter text in the calendar
and fields.To define the dates and times in the calendar, use the instructions in the following sections:

Click
to save the settings and create the calendar.The new calendar is added under the
element in the pane.In order to define a calendar, consider the days and times when alarm history and performance data should be captured. These time definitions can be created for a calendar or can be copied from an existing calendar.
Concerning defining overnight time definitions, if a time definition is set up to start on one day and finish sometime the next day (it runs overnight), on the first day the calendar is used, it starts at the start time specified by the time definition and there might be no overnight data collection. For example, assume the time definition specifies a peak time from 8 PM until 5 AM. On the first affected day, the calendar starts running at 8 PM, but does not continue to run from midnight until 5 AM on that first day. To capture this early morning time, you must define a separate time definition.
To define a new time definition to the calendar:
In the
section of the Create Calendar dialog box, click to open the Create Time Definition dialog box:Enter the following information to define the time definition:
Name: Name for the time definition.
Description: Description for the time definition.
Start/End Time: Starting and ending times for the time definition.
Use 24 hour period: Select to set the time definition to run a full 24 hours from the start time. Start Time and End Time are reset to 12:00 AM.
Recurrence: Select the interval for applying the time definition; for example, every day, every 2 weeks, and so on. Select
to select a specific start date/time and end date/time.Range: Set the start date and optional ending date.
Time Category: Click the
drop-down list, then select the appropriate category for the time definition (such as Peak, On/Off time, and so on).Click

The
section on the right side of the page consists of a two-month calendar and a weekly calendar. The weekly calendar displays shaded blocks of time to represent time definitions for the selected week. The colors correspond to the time definition category (Peak, On, Critical, and so on).Figure 13-3 illustrates how you can view the time definitions as colored blocks in the weekly calendar:

Select the
check box.Click the drop-down list, then select a time category:
Select the
check box.The calendar columns update to show the undefined time color.

.Cancel this Interval: Removes the time interval from the time definition for the selected date only. To restore the interval, right-click the interval, then select
.Select on Definitions Tree: Highlights the time definition associated with the interval. This is useful when many time intervals and definitions exist.
To edit a time interval or definition:

However, as an exception to the rule, data is collected during all blackout calendars when capturing SLA data, to ensure that data is available in the event that blackout periods change after data capture. In this case, the blackout data can be excluded when running SLA reports. For more information, see the Operations Center 5.0 Service Level Agreement Guide.
To create a blackout calendar for a specific element:
In the
pane, navigate to the element for which a blackout calendar is needed.Right-click the element, then select
to open its dialog box.Create Time Definitions as necessary to specify blackout times for the element.
For more information regarding creating calendars and defining time definitions, see Section 13.2.1, Creating Calendars.
