Introduction
Observability is the ability to understand the internal state of your system by looking at what is happening externally. In a software system, in order to acquire observability, we mainly implement the following aspects: logging, metrics, and tracing. Especially when we are moving away from monolithic software systems to microservices-based architectures, observability becomes a key aspect of the system design. Compared to monoliths, it’s much harder to troubleshoot issues and do performance tuning in microservices deployments. This is mainly due to the added complexity of working with a distributed system. Thus, your software system should understand these challenges, and be ready to handle any issues that may arise. Observability tools allow us to do this.
In this article, we will focus on three observability tools:
