Metrics

Infrastructure

Numbers tracked over time.

Counts and durations: requests per minute, error rate, response time. Cheap to keep for a long time and the right tool for "is this worse than yesterday". Cannot tell you about one specific user.

Observability

Infrastructure

Being able to tell what your system is doing.

The combination of logs, metrics and traces that lets you answer questions about a running system, including questions you did not anticipate when you built it.
