What are the Instrumentation tools?

Instrumentation tools are software applications and frameworks used to monitor, analyze, and optimize the performance of systems and applications. They gather metrics, logs, and traces to provide insights into system behavior, helping developers and operators troubleshoot issues, enhance performance, and ensure reliability. Common examples include Prometheus for monitoring, Grafana for visualization, and New Relic for application performance management. These tools are essential in modern DevOps and observability practices.
