Logging to a file

Since Payara Micro 4.1.1.163

This section describes how to print all the Payara Micro log messages into a file.

Logging to a file from the Command Line

To print all of the Payara Micro log messages into a file from the command line, you will need to use the --logToFile option, followed by either a path to where you want to put the log file or by giving the name of a file you want to print the logs into. If a file name is not given, a default file called payara-server.log is generated.

java -jar payara-micro.jar --logToFile /home/user/PayaraMicro.log

Logging to a file Programmatically

To print all the Payara Micro log messages into a file programmatically, you will need to use setUserLogFile(String filePath) method.

import fish.payara.micro.PayaraMicro;
import fish.payara.micro.BootstrapException;

public class EmbeddedPayara{

    public static void main(String[] args) throws BootstrapException{
         PayaraMicro.getInstance().setUserLogFile("/home/user/PayaraMicro.log").bootStrap();
    }
}
