Allows arbitrary keys and values to be added to the event MDC.
Allows arbitrary keys and values to be added to the event MDC.
*extra-mdc*clj
May contain a map of extra values to add to the logging MDC (message diagnostic context).
The keys of the map are converted to string (via clojure.core/name). The values of the map are converted to string via .toString(); null values are not added to the MDC.
Note: the appender adds values to the MDC, which is stored as a mutable value by Logback.
Values stored into the MDC may "stick" in the per-thread MDC data and be visible in
later logging, even after exiting the with-mdc block.
For best results, invoke set-mdc-default at application startup, setting
a default for each key that may later be added to the MDC
by a call to with-mdc.

set-mdc-defaultclj
(set-mdc-default defaults)Alters the root value for the *extra-mdc* var, merging keys and values.
Each key is converted to a string using name.
The value is usually an empty string.
This ensures that MDC set by with-mdc doesn't leak out into subsequent
logging on the same thread.
Alters the root value for the [[*extra-mdc*]] var, merging keys and values. Each key is converted to a string using `name`. The value is usually an empty string. This ensures that MDC set by [[with-mdc]] doesn't leak out into subsequent logging on the same thread.
with-mdccljmacro
(with-mdc mdc-values & body)Binds a map key/value pair into *extra-mdc* before evaluating the body.
Binds a map key/value pair into [[*extra-mdc*]] before evaluating the body.
