Add health check to gRPC services and use this command line tool to check for service status:
- https://github.com/grpc-ecosystem/grpc-health-probe

#grpc #health #health_check

ghz:
- Simple gRPC benchmarking and load testing tool inspired by hey and grpcurl.

sample ghz command to load test a service:

ghz --insecure --proto my_proto.proto --call my_proto.AService.MethodById -d '{"user_id": "5d32b19b6fea7a28de186b15"}' 0.0.0.0:9000

The sample output will be:

os.Rename in goLang?

Function signature:

func Rename(oldpath, newpath string) error

What Rename does?

Rename renames (moves) oldpath to newpath. If newpath already exists and is not a directory, Rename replaces it. OS-specific restrictions may apply when oldpath and newpath are in different directories. If there is an error, it will be of type *LinkError.
