Fly Behind the Scenes: Fresh Logging

Fly has replaced its entire logging platform with a new approach that involves using Vector, an efficient log processing tool written in Rust. The previous system used seven large Graylog servers to manage logs, but the volume of logs was too high for them to process quickly enough, leading to data loss. By implementing Vector and sending logs directly to Elasticsearch, Fly has improved its logging capabilities and made searching across applications easier with a common log schema. This new architecture also allows for more flexibility in sending logs to different service endpoints in the future.
