This task aims to provide clear direction and documentation regarding the future of Icinga within our alerting infrastructure. As we transition to Prometheus + Alertmanager, we need to ensure engineers understand how to handle new alerts and what the long-term plan for Icinga entails. This task will involve reviewing the Alerting Infrastructure Roadmap, creating a detailed migration plan, and effectively communicating this plan to all SRE teams.

Problem:

• Currently, there is a lack of clarity among engineers regarding how to handle new alerts and the overall direction for Icinga as we transition to Prometheus + Alertmanager.
• This uncertainty may lead to inconsistent alerting practices, potential knowledge gaps, and difficulty in maintaining a streamlined alerting approach.

Goals:

• Create comprehensive documentation outlining the Icinga migration plan and future state.
• Communicate the Icinga strategy effectively to all SRE teams, ensuring a smooth transition.
• Establish clear guidelines for handling new alerts during the transition period.
• Define long-term goals and expectations for Icinga's role within the alerting infrastructure.
