Health checks in the Apollo Router
Determining the router's status
Health checks are often used by load balancers to determine whether a server is available and ready to start serving traffic.
The Apollo Router supports a basic HTTP-level health check. This is enabled by default and is served at the URL path /.well-known/apollo/server-health. This returns a 200 status code if the HTTP server is successfully serving. It does not invoke any GraphQL execution machinery.
