Not all of your alerts should result in on-call responders being paged. By creating page rules for the webhooks you've set up, you can define the conditions under which an alert should trigger the paging of an on-call responder.
Watch this quick screencast for an overview of the steps you'll take below.
Select the Webhook
Go to Settings > Webhooks. Click Edit Webhook for the webhook where you'd like to add page rules.
Scroll to the Paging rules section and click Create page rule.
Create the Page Rules
Choose an action to perform.
Choose Page on-call member for specified service to page your team's on-call member based on your specified conditions.
Set the conditions to be met for the on-call member of your team to be paged.
Choose Resolve alert to resolve alerts received via the webhook based on conditions applicable to your team's requirements.
As in the previous step, set the conditions to be met for the alert to be resolved.
When you've created one or more page rules, the Paging rules section in your webhook's definition will look comparable to the below.
In the timeline, notice that messages appear when on-call is initiated, a responder is paged, and when a page is acknowledged, based on your on-call schedules, escalation policies, and page rules.
