Worked on the chronosphereio/terraform-provider-chronosphere repository to deliver a new alerting capability for Terraform users. Developed the SIGNAL_NOT_EXISTS condition operator for the chronosphere_monitor resource, enabling alerts when a monitored signal disappears. Updated the API schema and documentation to support this feature, using Go and JSON to ensure type-safe configuration and seamless integration. Removed deprecated API endpoints and cleaned up legacy configurations, reducing technical debt and improving maintainability. The work included regenerating models and enums to align with the latest API changes, as well as updating the CHANGELOG and providing practical usage examples to support adoption by the Terraform community.
