[Red5devs] Log messages

[Mondain]

For a warn or error message:- Basic (full block)

    try {
        some code here
    } catch (Exception e) {
        log.error("An error happened", e);
    }

- Detailed (1 param)

    log.error("An error happened for {}", myvar, e);

- Detailed (2 params)

    log.error("An error happened for {} in {}", new Object[]{myvar, myvar2},
e);


For regular log messages (debug, info)

- Basic

    log.info("My {} instanced", myvar);

- Three or more params

    log.info("My {} brown {} jumped over the {} dogs tail", new
Object[]{"quick", "fox", "lazy"});


Thats essentially what needs to go in the wiki..
