A complete observability platform integrates monitoring, logging, and traceability into a single system to analyze the performance of technological infrastructures. Tools such as Datadog, Splunk, and New Relic allow for detecting problems, understanding their cause, and optimizing applications in real time. Unlike traditional monitoring, which only shows basic metrics, observability provides a deep view of system behavior, helping to diagnose complex errors. This is essential for maintaining the stability of critical applications, reducing downtime, and ensuring a smooth user experience in modern IT environments.
