Message Structure

Here is the URL to do a remote log :

curl http://localhost:8666/log/?classname=com.mycompany.test&log=This is my log message message&sev=DEBUG&logdate=1426844546265&depth=4&senddate=1426844546265

{
	cl : "ClassName or identifier of the javascript that did the log",
	log : "Log Message",
	logdate : "Date of the log (as we are queuing the message to ensure the order of reception)",
	depth : "Depth of the call stack not used ",
	senddate:"Date when the log was send from the client (Must be UTC time so we can calculate the request time)",
	sev : "The severity of the log [DEBUG,INFO,ERROR,WARN]"
}

Web

open http://localhost:8666/www/ you will land on an interface allowing to see the log in web mode (search tool from the browser) and also see the occurency of call of a class (identifier). If you add a "Entering" keyword in your log in each of first line of your function, it will be able to draw a sequence diagram.

Options

• Filtering on the logs, this allow to display on the file and the console only what is matching the filter

remotelogger --filter mainpage

Only logs containing mainpage will be displayed

• Log file, by default the log is done on the console, if you want to store in a file.

remotelogger --logfile myfile.log

The web part of the remote logger can use firebase for live update.

remotelogger --firebase https://YOURURL.firebaseio.com
