Abstract

  • At LINE Taiwan, we decided to upgrade Loki using a canary deployment strategy.
  • Replaced Promtail with Vector to handle logs and send them to Loki.
  • Used Vector to replicate real traffic to the new Loki, helping us adjust Loki configurations.
  • Improved Loki labels with Vector, significantly enhancing Loki’s performance.
  • Ultimately saved nearly 70% in machine costs, minimizing backend storage burden.
