How to set up my logger?

[BrainStone]

Hello.

I am currently trying to set up logger. Meaning I want to determine which logging levels should be logged an which ones not. How can i do this?

 

(I didn't find any tutorials)

 

This is the code I'm currently using:

 

		// Somewhere in my preInit
	logger = event.getModLog();

	//Checks if mod is in debug mode (log all)
	if (BrainStone.debug) {
		logger.setLevel(Level.ALL);
	//Checks if mod is a release (log less)
	} else if (BrainStone.release) {
		logger.setLevel(Level.INFO);
	//Default (log some)
	} else {
		logger.setLevel(Level.FINE);
	}
	// Some other code

 

This does not work!

And I'm pretty sure why this does not work.

 

Here an extract from the documentation of the FMLPreInitializationEvent.getModLog method:

  Quote

Configurations can be applied through the config/logging.properties file, specifying logging levels for your ModID. Use this!

 

So how do I set everything up?

If you just want something simple, just use System.out.printf("message here %n") but that doesn't work with logging levels as far as I know

I can't believe that the Oracle Java Trails have nothing on the Logger API, so I googled a tutorial that didn't look too shabby:

Are you kidding me?

Look at this for an excellent example of how to set up a logger

I'm already doing this. And your example does not set up logging levels.

(Did you even read the question?)

[Pow3rCut]

It does set up Log levels e.g.

    public static void severe(String message) {

        log(Level.SEVERE, message);
    }

 

The Level is set to Severe.

I figured this out last night in my own code. The console log defaults to INFO level, and is not affected by setting log levels on the FMLLog. However, if you go check your Forge log files, I think you'll find all those missing FINEST/FINER/FINE messages being written out.

 

The console log cannot be changed via the "logging.properties" file; it is hard-coded in the initialization to "INFO", and the console logger object is private and cannot be accessed.

 

I decided for my own project a logging.properties file wasn't necessary because the FMLLog can be set internally, so I did not retain one.

 

However, if you want one, it goes in the top level of your config directory.  You can find an example one the one used by your JRE, with comments, in the jre/lib directory of your JDK. (In my case, that would be C:\Program Files\Java\jdk1.7.0_25\jre\lib\logging.properties). Don't tamper with that one, just use it as an example.  The general use of

it is discussed in the Java LogManager class documentation at http://docs.oracle.com/javase/7/docs/api/java/util/logging/LogManager.html.

 

Here's the important contents:

 

# Default global logging level
.level= INFO

 

would set the FMLlog and all child logs to default level of INFO, unless otherwise specified.

You can either specify otherwise programmatically, or by using the name of the logger (as set by "getLog()")

+ '.level'; e.g.

 

ForgeModLoader.level=ALL 

 

should set the FML file log to level.ALL, for example.

Thank you. This helped me! But there's still a problem. When I use this logging.properties file:

.level=ALL
BrainStoneMod.level=ALL
ForgeModLoader.level=ALL

(BrainStoneMod is my ModID) then still the fine/finer/finest levels are not displayed! I put it in mcp/jars/config. (That's the place where all other configs are located and in the beginning it says that ForgeModLoader logging level is set to ALL.)

 

What have I not seen? Or what could I do to fix this?

[Sinhika]

Are you looking at the console window in Eclipse for your messages, or at the '\forge\mcp\jars\ForgeModLoader-client-0.log" on your hard drive?  Like I said, you can't change the logging level of the console window; but if they are not showing up in the "ForgeModLoader-client-0.log" log file, something is definitely wrong.

 

 

[BrainStone]

Could you tell me where I can find the member or even better where I can the spot where the level.INFO is hard coded?

I'm thinking about using reflection to manipulate the logger during runtime. Which should make it possible to set the console logging Level for my logger to Level.ALL.

 

(Is ist possible to only do this to my logger?)

[hydroflame]

dude ... its hard coded in the java library... you dont want to change that .....

That would be insanely retarded to do

I mean, changing a part of the java standard lib, I like to believe it was made as it was for good reasons, and at your current level you probably don't understand them yet!

 

I don't know what the F you are trying to do or why, but I can promise you that if you feel you must resort to manipulating the standard libraries, you are doing something very very VERY wrong. I'd suggest you re-think your implementation plan and WHY you need to do it, there's probably a different way to accomplish whatever you really want to do..

[BrainStone]

Ok. To clear things up:

 

I have set up my mod and everything. And I have messages to log to the console. The messages have different levels off logging. (Ranging from SEVERE to FINEST) And depending on some flags I want them either to appear or not. For several reasons I cannot just use the output (Forge-client-log-0.log) for example because I need these messages to debug my code.

Now changing the logging levels of these messages isn't a good solution. I'd have to find the messages (might be pretty hard because there are many) change the logging level and after I'm done I have to change them back. Isn't there another solution to this?

 

I have also written a logger wrapper class: (It's very large)

why cant you just use System.out.println like 99% of us ? this seems like a lot of effort to see

You obviously haven't understood the use of a logger. It basically rates messages. And also can disable them based on their rating.

[hydroflame]

i obviously use a logger every single day of my life at work. but clearly it may be overkill for a minecraft mod... just saying. maybe im wrong and your mod is reaaaaaally big and you actualy need it. but i consider that im doing a big one and i dont need a logger

I don't NEED a logger but I really like the advantages of it. I first did not like it either. But now I really enjoy seeing instantly how important a message in the console is.

(And I guess a mod of 10k lines is no longer considered a small mod, is it?  )

[hydroflame]

yeah i understand, but this is a java issue not a forge issue, you should be able to find this in google easily

 

(btw mine has 18-19k , but yeah id consider 10k a big mod )

[BrainStone]

Please exuse me asking but what exactly should I ask google?

(I'm almost completly new to the whole logger thingy (Meaning I can log. But I do not have much experience))

[hydroflame]

[lmgtfy]how to use java logger[/lmgtfy]

 

im sorry

[BrainStone]

I did not mean that. I've created a logger wrapper class. I know how to log. But I don not know how to log levels lower than INFO to the console if this is not "allowed".

 

So i will ask that question on StackOverflow.com.

[BrainStone]

Well after doing some sirious research I found out that the following code should work:

 

logger.setLevel(myLevel);

for(Handler handler : loger.getHandlers()) {
  handler.setLevel(myLevel);
}

 

It does not and that for a specific reason:

 

In the class where the main logger is set up there is this line:

ConsoleLogThread.wrappedHandler.setLevel(Level.parse(System.getProperty("fml.log.level","INFO")));

 

Which basically sets the logging level for the console to Level.INFO in a way that makes it (almost (not sure if possible or not)) impossible to overwrite with your own logger. "ConsoleLogThread" is a private class in this class so I cannot access it.

 

So how could I still change this level for my logger? (The class the code is found: cpw.mods.fml.relauncher.FMLRelaunchLog)

 

I hope you understand my problem!

[Sinhika]

So why can't you just monitor the Forge-client log (or server log)? There are ways to tee that to a window, depending on what OS you are using. (In linux it would be "tail -f <filename>", of course)  Why does it have to be the console log?

[BrainStone]

First of all because I'm using windows. That means I don't have the tail command.

Then because I hate having billion of windows when I can have everything in one place!
