Java application performance tuning using Lightrun
Introduction In this article, I’m going to show you analyze a Java application using Lightrun so that you can discover various performance tuning improvements you could apply to your current Java application. In this previous article, I explained what Lightrun is and how you can use it to inject dynamic logs, capture runtime snapshots, or add dynamic metrics. In this article, I’m going to use Lightrun as an alternative to my JPA Association Fetching Validator.
Lightrun – the best way to debug production problems
Introduction In this article, I’m going to present you Lightrun, a very useful tool that I discovered recently while developing RevoGain, which helps me debug problems happening in production. Lightrun is like no other tool I’ve used before since it allows us to insert log entries dynamically at runtime, capture snapshots, and even inject metrics without changing your production code. This is especially useful when investigating issues reported by clients since we can figure out the problem while the user is executing the actions that can replicate the issue. Cool, right?
