Configure SMS Notifications for Critical Alerts in Stackdriver Monitoring

D.

Sure, I'd be happy to provide a detailed explanation of the options and which one would be the best approach for configuring SMS notifications for critical alerts in Stackdriver Monitoring on GCP.

Option A suggests downloading and configuring a third-party integration between Stackdriver Monitoring and an SMS gateway. This approach would require the team members to add their SMS/phone numbers to the external tool, which may be an additional step for them. It would also require additional maintenance to ensure that the integration is working correctly and any updates to either Stackdriver or the SMS gateway are reflected in the integration.

Option B recommends selecting the Webhook notifications option for each alerting policy and configuring it to use a third-party integration tool. This approach is similar to Option A in that it also requires the team members to add their SMS/phone numbers to the external tool. However, using Webhooks can be more flexible and powerful, allowing you to set up custom integrations that can perform specific actions when an alert is triggered. This approach may require more technical expertise to set up and maintain, but it can provide more control over the integration.

Option C suggests ensuring that team members set their SMS/phone numbers in their Stackdriver Profile. This approach is the simplest and most straightforward of the options presented. It requires no additional integration or configuration, and team members can easily manage their contact information in their Stackdriver profile. However, it does require team members to have access to and familiarity with Stackdriver, which may not be the case for all members of the team.

Option D recommends configuring a Slack notification for each alerting policy and setting up a Slack-to-SMS integration to send SMS messages when Slack messages are received. This approach would require setting up and configuring both Slack and a Slack-to-SMS integration tool. It would also require team members to add their SMS/phone numbers to the external integration. While this approach may work well for teams that already use Slack extensively, it may be more complicated and time-consuming to set up than the other options.

Considering the options presented, Option C is the best approach for configuring SMS notifications for critical alerts in Stackdriver Monitoring on GCP. It is the simplest and most straightforward approach, requiring no additional integration or configuration beyond setting up the alerting policies and ensuring that team members have their SMS/phone numbers in their Stackdriver profile. This approach is also the most likely to be accessible and familiar to all team members, as Stackdriver is a core tool for monitoring applications on GCP.
