[logback-user] Setting MDCFilter values at runtime

[Dan Cripe]

Unfortunately that won't fly either. Config file is embedded in the package
and the system is tightly locked down. We need to be able to change it via
some remote mechanism - HTTP, JMX etc.

You need to use Logback's ability to reconfigure itself to change the value
at runtime.  Just set scan="true" and change the file.

Thanks Ralph, but after reading the user guide and java docs I'm not seeing
how I can adjust this value at run time (only that I can set multiple
values).  Basically, if there's a problem reported, I want to be able to
use JMX or some other means to tell log back to start logging all messages
for user X (an MDC value) at DEBUG and then later revert back to normal
logging.

Is it possible to get a reference to an existing turbo-filter and then set
the value directly?  If so, I can create my own MBean that modifies the
filter as needed.

Use the DynamicThresholdFilter.

Hi- I'd like to leverage the MDCFilter TurboFilter, but I need to be able
to change the "value" element at runtime.  Basically, if a specific user is
having trouble, I want to set their logs to show up as DEBUG while the
remainder of the logs show up as INFO.  Is there a way (preferably using
JMX) that this can be done via configuration?  If not, what's the best
approach programatically?


Thanks,

Dan
