I deploy 7.10.1 ES cluster with ECK mode，when set slowlog but found the log not appear,
then I found in log4j2.properties


appender.index_search_slowlog_rolling.type = Console
appender.index_search_slowlog_rolling.name = index_search_slowlog_rolling
appender.index_search_slowlog_rolling.layout.type = ESJsonLayout
appender.index_search_slowlog_rolling.layout.type_name = index_search_slowlog
appender.index_search_slowlog_rolling.layout.esmessagefields=message,took,took_millis,total_hits,stats,search_type,total_shards,source,id

logger.index_search_slowlog_rolling.name = index.search.slowlog
logger.index_search_slowlog_rolling.level = trace
logger.index_search_slowlog_rolling.appenderRef.index_search_slowlog_rolling.ref = index_search_slowlog_rolling
logger.index_search_slowlog_rolling.additivity = false

appender.index_indexing_slowlog_rolling.type = Console
appender.index_indexing_slowlog_rolling.name = index_indexing_slowlog_rolling
appender.index_indexing_slowlog_rolling.layout.type = ESJsonLayout
appender.index_indexing_slowlog_rolling.layout.type_name = index_indexing_slowlog
appender.index_indexing_slowlog_rolling.layout.esmessagefields=message,took,took_millis,doc_type,id,routing,source
