Our internal IT teams have asked us to implement something similar to the /status REST endpoint that exists in Bitbucket's WebApp, but in Mesh.
The GRPC Health Checking Protocol should serve their needs: https://github.com/grpc/grpc/blob/master/doc/health-checking.md
Implemented in Mesh 1.4
This has been implemented in Mesh 1.4, however only the Check RPC has been implemented, not the Watch RPC. If you require the Watch RPC please open a separate suggestion.
What has been implemented simply returns SERVING at all times the process is running and able to accept RPCs. It does not imply the Mesh node is configured, etc. For detailed Mesh node status the Bitbucket WebApp must be contacted, as it's control plane knows the detailed state of the node.
