> #### Choosing a schedule for the monitoring plan

> A schedule defines the block of time for which a set of monitoring rules is active for a resource. When you add a monitoring plan to a resource, you specify the schedule to indicate when the monitoring plan will be active.

> Fathom provides several predefined schedules. You can use the schedules as they are, or you can modify them to suit your operating needs. You can also use an existing schedule as the basis for a new schedule, changing its name and characteristics.

> Note: The schedules discussed in this section refer to schedules you associate with resource monitors. Schedules that define frequency of an activity are associated with jobs, job templates, reports, and report templates. For specific information about job schedules, see Chapter 8, "Creating Jobs and Job Templates." For specific information about report schedules, see the relevant sections in the Reporting Guide.

> Each schedule you create appears, along with the Fathom-provided schedules, in the list frame under the Schedules category, as shown in Figure 4–1.

> Figure 4–1: Schedules

> ##### General scheduling considerations

> Keep the following points in mind regarding schedules:

> - Before you create a new schedule, it is useful to review the existing schedules to determine if you can use or simply modify an existing schedule.
> - You must create two separate schedules if you want to span an overnight period. For example, if you want to create a schedule that includes 8:00 PM through 8:00 AM, you must create two schedules:
> - 8:00 PM to 12 AM
> - 12:00 AM to 8:00 AM
> You must also select the appropriate days for each schedule.

> - You can schedule different rules to apply to a resource at different times and on different days. For example, you might want to monitor your OpenEdge databases more frequently during the week than on the weekends. To accomplish this, you can create and associate different schedules with each monitoring plan.
> - You can associate more than one schedule with a resource, but you cannot associate overlapping schedules with a single resource.
> - The selection list of available schedules for a monitoring plan does not include schedules that overlap their time or day criteria with other schedules or that are already in use by the resource.

> ##### Using predefined schedules

> Fathom provides several predefined schedules that you can use in your monitoring plan. You can also use any predefined schedule as the basis for a new schedule, which you can then modify to suit your needs.

> Table 4–1 describes the predefined schedules.

> Table 4–1: Predefined schedules
> Name | Block schedule defined for...
> --- | ---
> Default_Schedule | Sunday through Saturday, 24 hours per day. See the "Using the Default_Schedule" section for more details.
> Weekdays | Monday through Friday, 24 hours per day.
> Weekdays_Early_Morning | Monday through Friday from 12 AM to 8 AM.
> Weekdays_Evenings | Monday through Friday from 5 PM to 12 AM.
> Weekdays_Office_Hours | Monday through Friday from 8 AM to 5 PM.
> Weekends | Saturday through Sunday, 24 hours per day.

> All predefined schedules appear in the management console list frame under the Schedules category when you select Library from the menu bar, as shown in Figure 4–2.

> Figure 4–2: Predefined schedules

> Once you have created a resource monitor, you can edit an existing schedule or create a new schedule to associate with it at any time.

> ##### Using the Default_Schedule

> The Default_Schedule is a reusable 24/7 schedule that you can use or modify just as you can any other schedule, whether predefined by Fathom or created by you. However, the Default_Schedule is unique among all other schedules because:

> - Fathom automatically associates it with new resources when you create them.
> - You can edit it, but not delete or rename it.

> ##### Updating and deleting schedules

> Once your resource monitor exists, you can update its schedule at any time. This task is accomplished by accessing the monitoring plans for the resource and selecting another schedule from the drop-down list of currently available schedules.

> You cannot delete a schedule that is currently being used by a resource monitor.

> ##### Creating a new schedule

> You can create a new schedule from the Fathom Component Library.

> To create a new schedule:

> 1. Select Library from the menu bar. The Fathom Component Library page appears in the detail frame:

> 2. Click Create Schedule. The Schedule page appears.
> 3. Enter a name for the schedule in the Name field. You cannot enter spaces between words or use special characters such as an asterisk (*), ampersand (&), or period ( . ) in the Name field.
> 4. Enter a description of the schedule in the Description field. The Description field is for reference only. It appears in the schedule's title when you reaccess the schedule once you save it.
> 5. In the Schedule period, select the days and times you want the schedule to include (note that Days is a required field):

> 6. Click Save to save the schedule or Cancel to discard the schedule. If you save the schedule, the detail frame displays the days and times of the new schedule:

> You can edit the schedule you created, copy it to use as the basis for another new schedule, or delete it.
