all the configurations for this lib need to put into config.yaml file with the path set to environment CONFIG_FILE

export CONFIG_FILE=${CURDIR}/example/config/config.yaml
go run main.go

Clone from flogging of Hyperledger Fabric: https://github.com/hyperledger/fabric/tree/master/common/flogging

[1] import flogging "github.com/Hnampk/prometheuslog/flogging"

[2] Just define logger = flogging.MustGetLogger("services.abc.xyz")

[3] Then call logger.Info(...), logger.Warn(...), logger.Error(...) for logging

• sample configuration in config.yaml file:

Log:
    Level: INFO # DEBUG/INFO/WARN/ERROR (default: DEBUG)
    Format: "%{color}%{time:2006-01-02 15:04:05.000 MST} [%{module}] %{shortfunc} -> %{level:.4s} %{id:03x}%{color:reset} %{message}" # default: json

trace the process duration of a function

import "github.com/Hnampk/prometheuslog/gotracing"

var tracer = gotracing.MustGetTracer("mypackage")

func test(requestID string){
    tracer.StartFunction(requestID)
	defer accountTracer.EndFunctionWithDurationSince(requestID, time.Now())

    // do something
}
