"payload" :
	{	"abstract": "{{ctx.set off.title}}",
		"supply": " {{ctx.monitor.title}}",
		"severity": "essential",
		"custom_details":
			{ 
				"-Severity" : "{{ctx.set off.severity}}",
				"-Interval begin" : "{{ctx.periodStart}}",
				"-Interval finish": "{{ctx.periodEnd}}"
			}
	}
}

Word that aside from the custom_details part within the code, the remainder of the fields are obligatory for PagerDuty.

17. Select Ship check message and check to ensure you obtain an alert on the PagerDuty service.
18. Select Create and make sure the monitor was created efficiently.

A notification will probably be despatched to the PagerDuty service as a part of the check, which can set off a notification by way of a telephone name or textual content message for the one that is obtainable primarily based on the escalation coverage outlined earlier.
