I tried to send it to the pager duty and its seems like i have a problem ,
i talked with the opensearch and they offer this solution:
{ “event_action”: “trigger”,
“payload” :
{ “summary”: “{{ctx.trigger.name}} -Severity : {{ctx.trigger.severity}}\n -Period start : {{ctx.periodStart}}\n -Period end: {{ctx.periodEnd}}\n -Involved User: {{ctx.Username}}”,
“source”: " {{ctx.monitor.name}}",
“severity”: “critical”
}
}
And this works
