Health endpoints for Mule applications
Design reachable health endpoints whose response contracts reflect application outcomes, with correct listener routing, response encoding and input timeouts.
Expose Health Check endpoints from a Mule application.
~5 min read · 8 practice questions ·
What the exam expects
- Expose a dedicated health endpoint with an explicit probe contract.
- Separate listener address and route configuration from response generation.
- Match healthy and unhealthy responses to the flow's actual outcome.
- Choose response streaming and incoming-data timeout controls deliberately.
A listener receives HTTP requests; a base path prefixes its routes; a probe is a monitoring client; a response contract defines the status and representation the client interprets. The HTTP details here use Connector1.9, alongside Mule4.6 error handling.
Key facts
Managed readiness
- Detail
- Worker CloudHub checks the Mule Agent endpoint.
Business health
- Detail
- The application must implement the required dependency check.
Listener base path
- Detail
- Applies to listeners referencing that configuration.
Path choice
- Detail
- A specific path outranks a wildcard match.
Continued error
- Detail
- The owning scope completes successfully.
Propagated error
- Detail
- The owning scope fails.
Response NEVER
- Detail
- Determines the outgoing content length, consuming streams if needed.
Input read timeout
- Detail
- Bounds waiting for further request data.
- Why can a connector supply an error reason phrase without a custom expression?
- When does persistent-connection idle timeout apply?
- What happens to a connection after its first completed request if persistence is disabled?
