Observability Done Right: Best Practices and Anti-Patterns for Effective System Monitoring

Image
  WHAT Observability is a concept that refers to the ability to gain insights into the behavior and performance of complex systems. In the context of software engineering, observability involves the collection, analysis, and visualization of data from software applications, infrastructure, and other components of a system. In the animal kingdom, observability plays a critical role in survival, allowing animals to monitor their surroundings, detect threats, and find food. Dolphins use echolocation to observe their surroundings. They emit high-frequency sounds that bounce off objects, allowing them to create a 3D map of their environment.

Failfast Vs Failsafe in Java

Difference between fail-safe and fail-fast Iterator is becoming favorite core java interview questions day by day, reason it touches concurrency a bit and interviewee can go deep on it to ask how fail-safe or fail-fast behavior is implemented .  How does a system react when there is a failure characterizes it as a fail fast or a fail safe system. This article is to discuss whether fail safe or fail fast is better. Then what it has to do with java. Concept of fail-safe iterator are relatively new in Java and first introduced with Concurrent Collections in Java 5 like ConcurrentHashMap and CopyOnWriteArrayList. fail-fast Iterators in Java As name suggest fail-fast Iterators fail as soon as they realized that structure of Collection has been changed since iteration has begun . Structural changes means adding, removing or updating any element from collection while one thread is Iterating over that collection. fail-fast behavior is implemented by keepinga modification count and if iterat...
