AI Briefing[Case Study] Building the kt cloud PLATFORM Observability Alert Platform
Key point
kt cloud built an Observability Alert platform based on the LGTM stack, achieving organizational isolation and integration with centralized monitoring.
Details
In the KCP cloud environment, the LGTM stack consisting of Grafana, Loki, Tempo, and Mimir handled monitoring, but issues arose during Alert processing, including insufficient organizational isolation, scalability limitations, and the absence of standard APIs.
To address these issues, an in-house Alert management service was built instead of adopting external SaaS. Key design decisions were as follows:
- Namespace Prefix Approach: Alert isolation was implemented by injecting organization identifiers at the API layer without separate infrastructure isolation.
- Label Standardization: The Label scheme for Alert events was standardized to enable integration with centralized monitoring systems.
- API Layer Separation: Dependence on Grafana was reduced, and a standardized interface for creating and retrieving Alerts was provided.
As a result, a system was established that allows Alerts to be managed as operational policies rather than simple notifications.
