log4j

I recently discovered that there was log4j extension for application insights . So following the example online I attempted to configure application insights and log4j to log items from my servlets living in an azure hosted tomcat. Well, the example seems very incomplete as it never makes mention of the key at all. From looking through the source I see an example (test?) that uses <param> within the log4j.xml but not much explanation of how to use or debug the actual logger. Does anyone out there have any pointers on how to actually use/implement the ApplicationInsightsAppender for log4j? Here

I'm using log4j 2 and RollingFile appender: <RollingFile name="mylog" fileName="mylog.log" filePattern="mylog.log.%d{yyyy-MM-dd}.log"> <PatternLayout> <pattern>[%d] [%-5p] [%-8t] %F:%L %m%n</pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy interval="1"/> </Policies> </RollingFile> The log files do get renamed daily. But the Javadoc of FileRenameAction class indicates there is an option renameEmptyFiles which is false by default so if a day's log is empty it deletes it instead of rename it appending the date to the file name. How to configure it to true since I'd like to have the

Dubbo的 背景 　　随着互联网的发展，网站应用的规模不断扩大 　　常规的垂直应用架构已无法应对 　　分布式服务架构以及流动计算架构势在必行　　 　　亟需一个治理系统确保架构有条不紊的演进。 　　 单一应用架构 　　当网站流量很小时，只需一个应用，将所有功能都部署在一起，以减少部署节点和成本。 　　此时，用于简化增删改查工作量的 数据访问框架(ORM) 是关键。 垂直应用架构 　　当访问量逐渐增大，单一应用增加机器带来的加速度越来越小，将应用拆成互不相干的几个应用，以提升效率。 　　此时，用于加速前端页面开发的 Web框架(MVC) 是关键。 分布式服务架构 　　当垂直应用越来越多，应用之间交互不可避免，将核心业务抽取出来 　　作为独立的服务，逐渐形成稳定的服务中心，使前端应用 　　能更快速的响应多变的市场需求。 　　此时，用于提高业务复用及整合的 分布式服务框架(RPC) 是关键。 流动计算架构 　　当服务越来越多，容量的评估，小服务资源的浪费等问题逐渐显现 　　此时需增加一个调度中心基于访问压力实时管理集群容 量, 提高集群利用率。 　　此时，用于提高机器利用率的 资源调度和治理中心(SOA) 是关键。 什么是Dubbo 　　Dubbo是一个分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案，SOA服务治理方案。 　　简单的说，dubbo就是个服务框架

I am implementing logging in my java application , so that I can debug potential issues that might occur once the application goes in production. Considering in such cases one wouldn't have the luxury of using an IDE , development tools (to run things in debug mode or step thorough code) , it would be really useful to log class name , method name and line number with each message. I was searching the web for best practices for logging and I came across this article which says: You should never include file name, class name and line number, although it’s very tempting. I have even seen empty

In our logs we're seeing credit-card numbers due to people hitting some of the ULRs in our app with CC info (I have no idea why they are doing this). We want to sanitize this information (because of PCI considerations) and not even persist it to disk. Hence, I want to be able to sanitize the log entry before it hits the log file. I've been looking at Tomcat Valves (Access Log Valve). Is this the way to go? I was able to solve this problem by extending AccessLogValve and overriding public log(java.lang.String message) : public class SanitizedAccessLogValve extends AccessLogValve { private

My Java project uses Log4J2. Currently, it is successfully writing logs to a file. Now, I'm trying to push the logs to LogStash via a Socket Appender. Unfortunately, I am not having any success with these efforts. At this time, I'm looking at two pieces: my log4j2.xml file and my logstash config file. I've provided both here in hopes that someone can help me identify my problem. log4j2.xml <Configuration status="WARN" monitorInterval="30"> <Appenders> <Socket name="A1" host="0.0.0.0" port="4560"> <SerializedLayout/> </Socket> <RollingRandomAccessFile name="RollingFile" fileName="/logs/server
