Publish AWS SNS message to Pagerduty

Question

I have integrated pagerduty with AWS cloudwatch and I am trying to publish a message manually to a SNS Topic that is subscribed by pagerduty and email. But I am not able to get incidents in pagerduty. However, cloudwatch alarms are triggering incidents in pagerduty using this same topic.

I referred some document for pagerduty message payload. But unable to make it work. My SNS message JSON is as follows,

{
 "default":"test message",
 "email":"test email message",
 "https":{
    "service_key":"XXXX",
    "event_type":"trigger",
    "description":"Example alert on host1.example.com"
  }
}

Its not triggering an incident in pagerduty. I am not sure what I am missing in the request body. I am receiving email messages properly from this same message body. Could someone point out the mistake?

Thanks in advance.

Answer 1

To do so, you must choose the option Custom Event Transformer for the PagerDuty Integration. In the integration, you can write your own JavaScript code as follows:

var normalized_event = {
    event_type: PD.Trigger,
    description: "SNS Event",
    details: PD.inputRequest
};

PD.emitGenericEvents([normalized_event]);

To parse the received payload from SNS, you can use:

var rawBody = PD.inputRequest.rawBody;
var obj = JSON.parse(unescape(rawBody));

And treat obj to treat your event according to your SNS message.

I'm too late to answer this but still adding as @filipebarretto has suggested we need to use Custom Event Transformer for this type of integration.

Setup: ~ AWS Cloudwatch (RDS Metric) -> AWS SNS -> PagerDuty (CET)

I have successfully integrated AWS SNS to PagerDuty via Custom Event Transformer

var body = JSON.parse(PD.inputRequest.rawBody)
var message = body.NewStateReason

var normalized_event = {
      event_type: PD.Trigger,
      description: body.AlarmName,
      details: message
    };
PD.emitGenericEvents([normalized_event]);

The above code will send incident as AlarmName and details as NewStateReason.

I believe PagerDuty's native AWS CloudWatch integration is opinionated. So a Custom SNS message won't trigger an incident.

But PagerDuty has an inbound integration type that allows you to create a script using JS (ES5) to parse any custom message sent to the this integration - which can then trigger an incident based on the logic of your script.
