Tensu: Text UI for Sensu Go Observability

Two Sigma developed Tensu, an open-source terminal-based dashboard for interacting with the Sensu Go observability pipeline. Tensu provides real-time data on monitored events, allowing administrators to quickly assess system status, filter events using regular expressions, and interact with checks (resolve, silence, re-execute) directly from the terminal. This reduces context switching and improves efficiency during production deployments and system changes. The post details the rationale and design approach for building Tensu, emphasizing its speed, ease of use, and interactive nature, and highlights its contribution to improving confidence in production deployments.
