Health Check

RobustMQ exposes standard health check endpoints via the HTTP Admin Server, compatible with Kubernetes Liveness and Readiness Probes out of the box.

Endpoints

All endpoints are served by the Admin Server on the configured http_port (default 58080).

Endpoint	K8s Probe	Description
GET /health/ready	Liveness / Readiness Probe	Checks whether all configured ports are ready. Returns 200 OK when ready, 503 Service Unavailable when not
GET /health/node	Deep node check	Performs a deep status check on the current node. Not recommended for K8s probes
GET /health/cluster	Deep cluster check	Performs a deep status check on the cluster. Not recommended for K8s probes
