Hello does anybody know how to read .evt /.evtx which are Windows Event log files to read not using provided api's , I want to read them using FILE I/O apis in C/C++ . Or how to convert those files into .txt , I know splunk does this but not sure how they are doing this. I might be late but well, it could help a future reader so : To read an .evt file with standard lib (let's say in C++), you should be aware of ELF_LOGFILE_HEADER structure and EVENTLOGRECORD structure . In addition, here is the event log file format. Now everything is simpler, what you have to do is : I. Declare structures Log

Splunk是啥? Splunk是日志/流式数据领域中做的最好的商业软件实现,它的核心能力只有一个: 像Google那样搜索企业内部所有产生的日志 这个的威力非常大,现在的企业不缺数据,缺的是有效挖掘数据的能力。而显然大部分企业没有Google的能力去做搜索,于是Splunk提供这样的能力。与之相竞争的开源实现有Logstash。 Splunk ≈ Logstash Logstash = Redis(传输) + ElasticSearch(搜索) + Kibana(展现) ElasticSearch = Lucene + Search 那么,哪里可以买到呢?## Splunk官网上有,我就不替他们做广告了,总之,很贵,一万美元能买1G的流量每天。言归正传,我还是分析一下这个玩意儿的一些功能特性吧。 首先,Splunk有一个很炫酷的界面 可以看到,Splunk的主要使用方式就是那个搜索框,在里面输入一种叫做 SPL的搜索语言 ,就能获取到你想要的各种信息了。Splunk能在后台对数据进行过滤、聚合、统计,最后得到各种报表、图像 SPL是一种向SQL致(chao)敬(xi)的语言,语法非常的类似,不同的是,SPL搜索的不是关系数据库,而是输入到Splunk系统中所有的日志数据,以下是几个具体的案例: 可以看到,对于一行SPL搜索语句 sourcetype = syslog ERROR

前端异常监控解决方案研究

摘要: 异常监控不复杂也不简单啊... 原文: 前端异常监控解决方案研究 作者:frustigor 前端监控包括行为监控、 异常监控 、性能监控等,本文主要讨论异常监控。对于前端而言,和后端处于同一个监控系统中,前端有自己的监控方案,后端也有自己等监控方案,但两者并不分离,因为一个用户在操作应用过程中如果出现异常,有可能是前端引起,也有可能是后端引起,需要有一个机制,将前后端串联起来,使监控本身统一于监控系统。因此,即使只讨论前端异常监控,其实也不能严格区分前后端界限,而要根据实际系统的设计,在最终的报表中体现出监控对开发和业务的帮助。 一般而言,一个监控系统,大致可以分为四个阶段:日志采集、日志存储、统计与分析、报告和警告。 采集阶段:收集异常日志,先在本地做一定的处理,采取一定的方案上报到服务器。 存储阶段:后端接收前端上报的异常日志,经过一定处理,按照一定的存储方案存储。 分析阶段:分为机器自动分析和人工分析。机器自动分析,通过预设的条件和算法,对存储的日志信息进行统计和筛选,发现问题,触发报警。人工分析,通过提供一个可视化的数据面板,让系统用户可以看到具体的日志数据,根据信息,发现异常问题根源。 报警阶段:分为告警和预警。告警按照一定的级别自动报警,通过设定的渠道,按照一定的触发规则进行。预警则在异常发生前,提前预判,给出警告。 1 前端异常
