Hi All,
There is a library micrometer(https://micrometer.io/) used to collect metrics,
one of these metrics is a log rate, several calls for log.info, log.debug,
log.warn, etc.
Micrometer implements a
Filter(org.apache.logging.log4j.core.filter.AbstractFilter) and for each call
to the method filter we increment a counter.
After some research, I noticed that the method filter can be called multiple
times especially when an Async appender is configured and in this case, we have
a wrong logging rate. An application called on time the method
log.info("Test..") but the rate can easily be 2 instead of 1.
I tried to implement a solution but still not correct.
Now I am wondering if Filter still feasible for this use case, I am quite
convinced that will be not possible to use Filter to solve this.
So, now my question is: Is there another way to get the number calls for each
logging level? Or is there a workaround that can be implemented on the Filter
implementation to do the correct count?
