Observability Challenges

Yechezkel shares a compelling story about tackling data loss in a complex microservices environment, highlighting the arduous two-month process of instrumenting their application with millions of counters. He contrasts this experience with the proactive approach taken at Ground Cover, where they built a robust monitoring system from the ground up. The discussion then shifts to EBPF, a technology that allows for safe and efficient extensions to the Linux kernel, emphasizing its potential for enhancing observability without compromising application performance.
