Filter::MDC(3)

🌸 NAME 🌸

Log::Log4perl::Filter::MDC — a filter to match on values of a MDC key. This is the Filter::MDC(3) page, bestie: user contributed Perl documentation, here to make your logging config make sense. 🫶

✨ SYNOPSIS ✨

Okay so here's the setup — keep it exactly like this, no freestyling the spelling:

log4perl.filter.Match1               = Log::Log4perl::Filter::MDC
log4perl.filter.Match1.KeyToMatch    = foo
log4perl.filter.Match1.RegexToMatch  = bar

💅 DESCRIPTION 💅

This Log4perl filter checks if a predefined MDC key, as set in KeyToMatch, of the currently submitted message matches a predefined regex, as set in RegexToMatch.

That's it, that's the whole plot. It's giving "little key-value detective" energy: you tell it which MDC key to look at, you give it a regex, and it does the matching thing. 🔥
