# Health Checker

A simple way to gauge the health of a VerneMQ cluster is to query the `/health` path on the [HTTP listener](/1.9.0/configuration/http-listeners.md).

The health check will return **200** when VerneMQ is accepting connections and is joined with the cluster (for clustered setups). **503** will be returned in case any of those two conditions are not met.
