David,
Parameterized logging is not available for exceptions. Given that exceptions by
definition are rare, you don't need to optimize logging for them. You just write:
logger.error("Something went wrong because " + someReason, exception);
The difference in performance is measured in terms of microseconds which is
usually not significant in case of exceptions.
Does the above make sense?

Hi,
First, I was looking for a more recent log framework than log4j and I
just discovered logback : thanks for this great piece of software. I am
using it for a couple of hours now and I have a question about usage :
With log4j i had :
logger.error("Something went wrong because " + someReason, exception);
But with logback (SLF4J) I have to keep this since the signature is :
void org.slf4j.Logger.error(String msg, Throwable t)
I would have thought that something like below had existed :
void org.slf4j.Logger.error(String msg, Throwable t, Object[])
so i would have written
logger.error("Something went wrong because {}", exception, someReason);
Any advice ? Thanks
David
