GCP: Way to get "paged" via the GCP Cloud Console Android app?
Solution 1:
There are a lot of supported notification channel types available to get notified for Cloud Monitoring alerts. Email, SMS, Webhooks and PagerDuty to name a few. And since you already have a working setup in PagerDuty, same as what Michael Hampton, I would recommend for you to integrate that to Cloud Monitoring.
To configure a PagerDuty notification channel in GCP, you may follow the steps in this documentation.
Additionally, please keep in mind that Google recommends that you create multiple notification channels for your alert policies as they have no control on most of the delivery system options once the notifications have been passed.
To learn more on alerting policies, you can check this documentation.
