説明

Please describe the feature request.

Now the Log4j2Metrics will count all log events with all levels, that can be noisy if we don't care about some loggers, we don't want the loggers be collected into the log4j.events counters

We are hoping that we can exclude some loggers from being collected by the Log4j2Metrics.

For example:

I don't want the logger of "com.a.b.c" to be collected by the Log4j2Metrics

調査方針
Start by examining the Log4j2Metrics class in the micrometer core module to understand how log events are currently collected. Look for existing filter or exclusion mechanisms in other Micrometer metrics implementations (e.g., JvmMetrics, TomcatMetrics) for inspiration. The goal is to add a configuration option (e.g., through MeterFilter or a properties file) that allows excluding certain logger names from being counted. Check the issue comments for any maintainer suggestions or user feedback. Review the source code at https://github.com/micrometer metrics/micrometer/tree/main/micrometer core/src/main/java/io/micrometer/core/instrument/binder/logging for context.
