JustLog takes logging on iOS to the next level. It supports console, file and remote Logstash logging via TCP socket with no effort. Support for logz.io available. At Just Eat, logging and monitoring are fundamental parts of our job as engineers. Whether you are a back-end engineer or a front-end one, you'll often find yourself in the situation where understanding how your software behaves in production is important, if not critical. The ELK stack for real-time logging has gained great adoption over recent years, mainly in the back-end world where multiple microservices often interact with each other.
