Prometheus

Observability is crucial for understanding how your application operates in real-time. Among various observability signals—such as logs, traces, and continuous profiling—metrics play a significant role. They provide sampled measurements throughout the system, essential for ensuring service quality, improving performance, scalability, debuggability, security, and enabling real-time, actionable alerting. Building observable applications begins with proper instrumentation. While the Prometheus ecosystem offers tools that simplify this process, there are still numerous opportunities for mistakes or misuse. ...

Live Website: The Zen of Prometheus In modern days, we run our applications as loosely coupled microservices on distributed, elastic infrastructure as (mostly) stateless workloads. Under these circumstances, observability is the key to understanding how our applications run and behave in action to deliver highly available and resilient service. Prometheus is born in such an atmosphere as a solution to satisfy the observability needs of the cloud-native era. Among many other observability signals like logs and traces, metrics play the most substantial role. Sampled measurements observed throughout the system are crucial for monitoring the health of the applications and they enable real-time, actionable alerting. Although the tools in the Prometheus ecosystem make life a lot easier, there are still numerous possibilities to make mistakes or misuse them. ...
