> Reporter: Samuel Martin
> Priority: Major
> Labels: Filtering, Logger
>
> According to the documentation, Filters can be applied in different places:
> among others, as global filters applied to the whole configuration, to
> individual Appenders or... to individual loggers. However, when trying to
> configure a filter within a Logger, it doesn't seem to be applied.
> After debugging the issue, I think I have traced it to these lines within
> {{org.apache.logging.log4j.core.Logger$PrivateConfig}} internal class:
> {code:java}
> boolean filter(final Level level, final Marker marker, final String
> msg) {
> final Filter filter = config.getFilter();
> if (filter != null) {
> final Filter.Result r = filter.filter(logger, level, marker,
> msg);
> if (r != Filter.Result.NEUTRAL) {
> return r == Filter.Result.ACCEPT;
> }
> }
> return level != null && intLevel >= level.intLevel();
> }
> {code}
> The first line is retrieving the filter from the global configuration
> {{config.getFilter()}} instead of this logger's filter (if any)
> {{loggerConfig.getFilter()}}. The global configuration filter is applied,
> while the latter is simply ignored.
> Some additional notes follow:
> * The same reasoning applies at least to the other {{filter(...)}} methods
> in the PrivateConfig class.
> * According to the documentation, the {{LoggerConfiguration}}'s level is
> applied before the filters; but the code above doesn't say exactly the same
> (if the filter result is {{ACCEPT}}, then the event is not filtered,
> regardless the {{LoggerConfiguration}}'s level.
> * This is in practice a duplicate of LOG4J2-1965. I don't know why it was
> closed by the author just after having opened it, nor how it has not been
> fixed since then.
