Q: Does serverInfo return a success mean the policies have been loaded correctly as well? I’m moving cerbos from a server model behind an load balancer to a sidecar, meaning it’ll be deployed far more frequently and want to make sure 🙂

I don't know the answer to your question off hand, but we use

/_cerbos/health

for the same purpose to check the liveness/readiness of the sidecar. Our application then makes use of the gRPC Health API to programatically interact with the health of the sidecar.

Makes sense. I’ve been using serverInfo as my proxy for this and have used the GRPC health-check as well.
