Microprofile Health

Since Camel 3.0

The microprofile-health component is used for bridging Eclipse MicroProfile Health checks with Camel’s own Health Check API.

This enables you to write checks using the Camel health APIs and have them exposed via MicroProfile Health readiness and liveness checks.

Maven users will need to add the following dependency to their pom.xml for this component:

    <!-- use the same version as your Camel core version -->


This component provides a custom HealthCheckRegistry implementation that needs to be registered on the CamelContext.

HealthCheckRegistry registry = new CamelMicroProfileHealthCheckRegistry();
camelContext.setExtension(HealthCheckRegistry.class, registry);

By default, Camel health checks are registered as both MicroProfile Health liveness and readiness checks. To have finer control over whether a Camel health check should be considered either a readiness or liveness check, you can extend AbstractHealthCheck and override the isLiveness() and isReadiness() methods.

For example, to have a check registered exclusively as a liveness check:

public class MyHealthCheck extends AbstractHealthCheck {

    public MyHealthCheck() {

    protected void doCall(HealthCheckResultBuilder builder, Map<String, Object> options) {
        builder.detail("some-detail-key", "some-value");

        if (someSuccessCondition) {
        } else {

    public boolean isReadiness() {
        return false;
