Observability is a key feature of the Banzai Cloud Pipeline platform - we put significant effort into monitoring and centralized log collection - and, recently, into tracing. Instrumentation Instrumentation is the process of monitoring/measuring software performance, writing logs and trace information and, more generally speaking, of collecting information that helps us to diagnose errors, run software with maximum availability, to understand how the software operates and, more importantly, how it impacts users and businesses.
