Hello!  
does elasticsearch keep any change in log4j2.properties until a restart ?

im changing Logging to delete the logs by time not by size:

```auto
appender.rolling.strategy.action.condition.nested_condition.type = IfLastModified 
appender.rolling.strategy.action.condition.nested_condition.age = 7D

```

Thnaks in advanced!

AFAIK Logstash can only reload data transformation .conf files not own configuration .properties and .yml Whenever I have changed any settings, have to restart Logstash.
