The log package is used by Go services to log messages to STDOUT.

How To Use

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

import "github.com/IOTechSystems/go-mod-edge-utils/pkg/log"

To send a log message to STDOUT, you first need to create a Logger 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).

logger = log.InitLogger("SERVICE_NAME", configuration.LogLevel, nil) 

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

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