At 3 a.m., PagerDuty alerts trigger a flurry of activity as DevOps engineers scramble to diagnose issues, with logs, metrics, and traces scattered across multiple tools. To solve the fragmentation problem, Last9 built an observability platform that centralizes telemetry data, making it easier, faster, and more cost-effective to analyze. The company's telemetry control plane provides users with control over their data, allowing them to filter, reshape, and drop data in real-time without instrumentation or code changes. ClickHouse, a high-performance columnar database, is at the heart of Last9's platform, enabling fast query performance, scalability, and accessibility. By combining ClickHouse with AI-powered observability tools, Last9 aims to redefine observability and give teams real control over their telemetry data, leading to less guesswork, faster insights, and fewer 3 a.m. firefights.
