How to limit the number of files per day when using Logback SizeAndTimeBasedFNATP

由 ≡放荡痞女 提交于 2021-02-08 17:22:59
问题 When using the Logback SizeAndTimeBasedFNATP triggering policy, how can the number of files per day be limited? For example, on any given day, I don't want to have more than 100MB of logs. Given that each log (in the example below) is 20MB, I would want to be able to set a max limit of 5 files per day. The FixedWindowRollingPolicy provides a maxIndex property, but the TimeBasedRollingPolicy does not have maxIndex. Is there a recommended approach to applying a maxIndex when using the

【分库分表】sharding-jdbc—分片策略

由 五迷三道 提交于 2021-02-08 14:58:29
一、分片策略 Sharding-JDBC认为对于分片策略存有两种维度： 数据源分片策略（DatabaseShardingStrategy）：数据被分配的目标数据源 表分片策略（TableShardingStrategy）：数据被分配的目标表 两种分片策略API完全相同，但是表分片策略是依赖于数据源分片策略的（即：先分库然后才有分表） 二、分片算法 Sharding分片策略继承自ShardingStrategy，提供了5种分片策略： 　　 由于分片算法和业务实现紧密相关，因此Sharding-JDBC并未提供内置分片算法，而是通过分片策略将各种场景提炼出来，提供更高层级的抽象，并提供接口让应用开发者自行实现分片算法。 StandardShardingStrategy 标准分片策略。提供对SQL语句中的=, IN和BETWEEN AND的分片操作支持。 StandardShardingStrategy只支持单分片键，提供PreciseShardingAlgorithm和RangeShardingAlgorithm两个分片算法。 PreciseShardingAlgorithm是必选的，用于处理=和IN的分片。 RangeShardingAlgorithm是可选的，用于处理BETWEEN AND分片，如果不配置RangeShardingAlgorithm，SQL中的BETWEEN

Logging some request headers with DropWizard

由 こ雲淡風輕ζ 提交于 2021-02-08 07:33:55
问题 We're trying to add a custom http header to dropwizard access logs. We tried dropwizard 0.9.1 and 0.9.2, but can't find a way to do this. We noticed the following: server.requestlogs.appenders[file].logFormat is being ignored. It always logs using the common logging format. logging.appenders[file].logFormat is honoured, but web specific stuff results in %PARSER_ERROR[..] for things like %header{HEADER-NAME}, %A, etc. Is there a way to log such information? 回答1: It is possible to use a custom

SLFJ4 bridge for the Maven logger

由 余生长醉 提交于 2021-02-08 05:36:38
问题 I'm writing a Maven 3.x plugin and want to log with SLF4J & Logback. I found some SLF4J bindings for the Maven Logger: http://www.jcabi.com/jcabi-maven-slf4j/index.html https://bitbucket.org/peachjean/slf4j-mojo However, these seem to be SLF4J bindings but I believe what I need is a bridge for the Maven Logger i.e. to bridge/route all Maven log statements to SLF4J and use LogBack binding with logback.xml config. 回答1: You can use SLF4J directly from Maven plugin since Maven 3.1: The standard

kafka集群管理工具kafka-manager部署安装

一、kafka-manager 简介 为了简化开发者和服务工程师维护Kafka集群的工作，yahoo构建了一个叫做Kafka管理器的基于Web工具，叫做 Kafka Manager。这个管理工具可以很容易地发现分布在集群中的哪些topic分布不均匀，或者是分区在整个集群分布不均匀的的情况。它支持管理多个集群、选择副本、副本重新分配以及创建Topic。同时，这个管理工具也是一个非常好的可以快速浏览这个集群的工具，有如下功能： 1.管理多个kafka集群 2.便捷的检查kafka集群状态(topics,brokers,备份分布情况,分区分布情况) 3.选择你要运行的副本 4.基于当前分区状况进行 5.可以选择topic配置并创建topic(0.8.1.1和0.8.2的配置不同) 6.删除topic(只支持0.8.2以上的版本并且要在broker配置中设置delete.topic.enable=true) 7.Topic list会指明哪些topic被删除（在0.8.2以上版本适用） 8.为已存在的topic增加分区 9.为已存在的topic更新配置 10.在多个topic上批量重分区 11.在多个topic上批量重分区(可选partition broker位置) kafka-manager 项目地址： https://github.com/yahoo/kafka-manager 二

Logback - Layout & Pattern in logback.xml

由 拟墨画扇 提交于 2021-02-07 20:10:25
问题 I am using logback with slf4j for logging in Spring Boot application. I have created a custom layout class because all log statements are to be wrapped as a json. I have configured the logback-spring.xml as show below to take the custom layout. It works! Issue is I am unable to apply the pattern. Only either the layout works (or) the pattern. What I want is always on log, go to layout class and then apply the pattern before logging. <appender name="FILE" class="ch.qos.logback.core.rolling
