如何在log4j2.properties上添加服务器删除条件？

Question

我们正在使用ElasticSearch 6.1.1

这是log4j2.properties上的默认滚动文件：

appender.rolling.type = RollingFile
appender.rolling.name = rolling
appender.rolling.fileName = ${sys:es.logs.base_path}${sys:file.separator}${sys:es.logs.cluster_name}.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c{1.}] %marker%.-10000m%n
appender.rolling.filePattern = ${sys:es.logs.base_path}${sys:file.separator}${sys:es.logs.cluster_name}-%d{yyyy-MM-dd}-%i.log.gz
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 1GB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.fileIndex = nomax
appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.basepath = ${sys:es.logs.base_path}
appender.rolling.strategy.action.condition.type = IfFileName
appender.rolling.strategy.action.condition.glob = ${sys:es.logs.cluster_name}-*
appender.rolling.strategy.action.condition.nested_condition.type = IfAccumulatedFileSize
**appender.rolling.strategy.action.condition.nested_condition.exceeds = 2GB**

当日志文件超过2GB空间时，只有一种删除条件。

当日志文件超过7天时，我想添加第二个可选条件。

我已应用了以下更改：

appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.basepath = ${sys:es.logs.base_path}
appender.rolling.strategy.action.condition.type = IfFileName
appender.rolling.strategy.action.condition.glob = ${sys:es.logs.cluster_name}-*
appender.rolling.strategy.action.condition.nested_condition.type = IfAny
appender.rolling.strategy.action.condition.nested_condition.type = IfAccumulatedFileSize
appender.rolling.strategy.action.condition.nested_condition.exceeds = 2GB
**appender.rolling.strategy.action.condition.nested_condition.type = IfLastModified
appender.rolling.strategy.action.condition.nested_condition.age = 7D**

但是我做错了，因为我无法获得想要的结果。

任何人都可以向我展示任何示例如何在log4j2.properties上添加两个或多个删除条件？

谢谢和亲切的问候

尝试以下配置DeleteAction-

appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.basepath = ${sys:es.logs.base_path}
appender.rolling.strategy.action.condition.type = IfFileName
appender.rolling.strategy.action.condition.glob = ${sys:es.logs.cluster_name}-*
appender.rolling.strategy.action.condition.nested_condition.type = IfAny
appender.rolling.strategy.action.condition.nested_condition.fileSize.type = IfAccumulatedFileSize
appender.rolling.strategy.action.condition.nested_condition.fileSize.exceeds = 2GB
appender.rolling.strategy.action.condition.nested_condition.lastMod.type = IfLastModified
appender.rolling.strategy.action.condition.nested_condition.lastMod.age = 7D

您可以在文档中查看更多示例log4j2

注意：此示例中的关键行是这一行：

appender.rolling.strategy.action.condition.nested_condition.type = IfAny

这会将log4j2配置为在满足任何条件（> 2GB或最后修改的7D +）时删除。
