Observability

Introduction to observability

Joule provides process monitoring through JMX beans. Each processing unit (i.e. processors, metrics engine, transports etc) are instrumented with a generic monitoring pattern, JMX beans, that enables visibility in to the current processing state.

Observability and Metrics

Each OOTB processor record and presents event metrics to JMX monitoring platforms. This provides direct insight into how a streaming use case is performing.

Metrics available

• Received

• Processed

• Failed

• Discarded

• Ignored

• Average processing latency

All of these metrics are enabled by default and presented as JMX beans on the standard monitoring ports.
