Mutual transport layer security (mTLS) is an important subject among security, reliability, and engineering professionals who need to secure API communication as well as communication between machines and the applications and services they run. And for good reason: in 2022, the global average cost of a data breach was US$4.35 million, and almost double that in the United States at US$9.44 million.
Metrics are an important component of monitoring and observability. They provide information about specific durations of measured occurrences. In OpenTelemetry (OTEL), metrics play a huge role in providing visibility into the performance and health of an application. It has become a de facto standard among cloud-native apps for monitoring and observability solutions. Hence understanding OpenTelemetry metrics and when to use them will help you optimize your observability efforts.
