How to generate *.pb.go?

Enter goinfer/api folder!

export GOPATH=$(go env GOPATH)
export PATH=$PATH:$GOPATH/bin
protoc -I/usr/local/include -I. -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis --go_out=plugins=grpc:. api.proto
protoc -I/usr/local/include -I. -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis --grpc-gateway_out=logtostderr=true:. api.proto

How to profile performance

go tool pprof localhost:8080/debug/pprof/profile?seconds=<NUM_SECONDS>`
go tool pprof -http=:9090 /path/to/profile/pprof.pb.gz

How to configure monitoring

• Download and install Prometheus. See instalation guide
• Run Prometheus server prometheus --config.file ./config/prometheus.yaml from your terminal
• Download and install Grafana. See installation guide
• Run grafana (default address localhost:3000) with the following commands
  • sudo systemctl daemon-reload
  • sudo systemctl start grafana-server
  • sudo systemctl status grafana-server
• Open grafana UI, create prometheus date source, create dashboard (or use already configured one from this repository)
