Why 9090 is special

Prometheus pulls metrics from services rather than having them pushed, which means the monitoring system holds the list of what should exist. A service that vanishes is then detectable by its absence.

Connection
Prometheus scrapes metrics on a schedule and Kafka retains a log. Both are built on the principle that the system observing should hold its own record rather than trusting what it is sent.

Technology & computing

  • Prometheus scrapes targets on a schedule instead of accepting pushed metrics. The consequence is that a service which disappears entirely is still noticed, because the monitor knows it should have been there.
