README

This package contains the logging client written in the Go programming language. The logging client is used by Go services or other Go code to log messages to STDOUT.

How To Use

To use the logging client package you first need to import the library into your project:

import "github.com/edgexfoundry/go-mod-core-contracts/v4/clients/logging"

To send a log message to STDOUT, you first need to create a LoggingClient with desired Log Level and then you can send log messages (indicating the log level of the message using one of the various log function calls).

loggingClient = logger.NewClient(internal.CoreDataServiceKey,configuration.Writable.LogLevel) 

loggingClient.Info("Something interesting")
loggingClient.Infof("Starting %s %s ", internal.CoreDataServiceKey, edgex.Version)
loggingClient.Errorf("Something bad happened: %s", err.Error())

Log messages can be logged as Info, Debug, Trace, Warn, or Error
