Lagom metrics come from Lightbend Telemetry (Cinammon), and describe performance of the Lagom circuit breakers. Lagom applications may also be covered by Play and Akka monitoring, for HTTP and actor performance.
Lagom services that communicate with remote services have the ability to break the circuit when the remote is failing. The
lagom_circuit_breaker_state alerts when circuit breakers are active and normal communication is not happening.
Lightbend Telemetry provides a three way state gauge as lagom_circuit_breaker_state
