Health

The connector reports its health status using the Spring Boot Actuator health endpoint.

To configure the information returned by the health endpoint, configure the following properties:

management.endpoint.health.show-details
management.endpoint.health.show-components

For more information about the health endpoints, see Spring Boot documentation.

Health for the workflow, Solace binder, and the messaging service's binder components are exposed when management.endpoint.health.show-components is enabled. For example:

management: 
  endpoint:
    health:
      show-components: always 
      show-details: always

This configuration would always show the full details of the health check including the workflows and binders. The default value is never.

Workflow Health

A workflows health indicator is provided to show the health status for each of a connector’s workflows. This health indicator has the following form:

{
  "status": "(UP|DOWN)", 
  "components": {
    "<workflow-id>": { 
      "status": "(UP|DOWN)", 
      "details": {
        "error": "<error message>"
      }
    }
  }
}

Health Status	Description
`UP`	A status that indicates the workflow is functioning as expected.
`DOWN`	A status that indicates the workflow is unhealthy. Operator intervention may be required.

Google Cloud Pub/Sub Binder Health
