How can i implement or Automate some steps which will send certificate renewal status to custom channel ( e.g Email or Pagerduty/NewRelic) with condition something like ( If certificate is going to expire in 30 days, send notification)
i have found, AWS ACM does not renew imported certificates, and it sends expiration notifications on PHD ( Personal health dashboard as event notifications) https://docs.aws.amazon.com/acm/latest/userguide/check-certificate-renewal-status.html
is there a way i can use above functionality/service to automate desired steps.
You can use the Lambda function to send alerts to Slack and other systems based on PHD(Personal health dashboard) notifications. There is also an option to send an email/SMS via AWS SNS based on these events. You can find more details here
