On-call schedules define which O&M engineers receive alert notifications and when. Each schedule assigns shifts to engineers in a defined rotation. When an alert fires, ARMS sends notifications only to the engineer currently on duty -- by phone call, text message, email, or DingTalk message -- rather than the entire team.
A schedule does not trigger notifications on its own. You must link it to a notification policy or escalation policy for alerts to reach on-duty engineers. See Next steps.
How schedules work
A schedule contains one or more shifts. Each shift defines:
Who is on duty -- one or more contacts rotating in a set order
When the shift starts and what hours it covers each day
How often contacts rotate -- daily, weekly, or a custom interval
On-duty time ranges across shifts within the same schedule cannot overlap.
Prerequisites
Before you begin, make sure that you have:
A DingTalk, Lark, or WeCom group for shift change notifications, with all participating O&M engineers added to the group
All participating O&M engineers added as contacts in ARMS. See Contacts
A chatbot created for the DingTalk or WeCom group to receive notifications. See DingTalk chatbots
Create a schedule
-
Log on to the ARMS console. In the left-side navigation pane, choose .
Click the Schedule Management tab, and then click Create Schedule.
Enter a name for the schedule in the text box at the top of the right section.
In the Shift 1 section, configure the following parameters:
Parameter Description Person on Duty Select the contacts who rotate through this shift. After selecting contacts, drag them to set the rotation order. Contacts rotate in the order shown. Only O&M engineers already added as contacts appear in this list. Start Time The date when the shift rotation begins. Set On-duty Time The daily time range during which this shift is active, for example, 09:00--18:00. Shift Change Cycle How often contacts rotate: Every Day -- each contact covers one day, then hands off to the next. Weekly -- each contact covers one full week. Custom -- each contact covers a specified number of hours. (Optional) Click + Add Shift to add more shifts. Use multiple shifts to cover different time ranges within the same day -- for example, one shift for business hours and another for after-hours coverage.
Click Preview to verify the schedule.
From the Shift Change Notification drop-down list, select the chatbot for the group that receives shift change notifications.
Click Save.
The new schedule appears in the left section of the Shift Management tab.
Assign a substitute
If an O&M engineer is unavailable for a scheduled shift, assign a substitute to cover it. This reassigns only the specific shift without changing the underlying schedule.
In the left section of the Shift Management tab, click the schedule name. In the right section, click Create Substitute.
In the Create Substitute dialog box, set the Shift Time and Substitute parameters, and then click OK. The updated assignment is reflected in the schedule.
(Optional) To replace an existing substitute, click Current Substitute in the upper-right corner of the tab, delete the current substitute, and then assign a new one.
Manage schedules
The Shift Management tab supports the following operations:
| Action | Steps |
|---|---|
| View engineers in a schedule | Click the expand icon to the left of the schedule name, and then click an engineer's name to view their assigned shifts. |
| Edit or delete a schedule | Click the more icon to the right of the schedule name, and then click Edit or Delete. |
| Edit, refresh, or delete from the detail view | Click the schedule name. In the upper-right corner, use the corresponding icons. |
Next steps
A schedule takes effect only after you link it to a policy. Choose one of the following:
Notification policy: Add the schedule so that alert notifications go directly to the on-duty engineer. See Create and manage a notification policy.
Escalation policy: Add the schedule to an escalation level so that unresolved alerts are routed to the on-duty engineer at that level. See Configure an escalation policy.
