前言
ELK设置后抓日志非常好用，当然也不只是用于抓日志。功能强大，全文检索等等。
以下文章不定时更新。

ELK的Kibana
ELK的Filebeat
一、概念
Filebeat是Elastic Stack中的一个轻量级数据传输工具，专门用于转发和集中化日志数据。它的设计目的是高效地读取和转发日志文件到Elasticsearch或Logstash，进而帮助用户进行日志分析和监控。以下是对Filebeat的详细介绍，包括其主要功能、架构、使用场景和配置示例。
1. 主要功能
1.轻量级：Filebeat是一个轻量级的代理，不会对源系统造成显著的负担，适合在各种环境中部署。
2.日志采集：可以监控和采集本地的日志文件，并将其转发到指定的目标。
3.数据转换：支持对日志数据进行简单的处理，例如解析和格式化。
4.容错性：在目标不可用时，Filebeat可以缓冲数据，确保不会丢失日志信息。
2. 架构
Filebeat的架构主要包括以下几个部分：
5.输入：定义要采集的日志文件及其路径。
6.处理：可以对输入的数据进行处理，包括解析、添加字段等。
7.输出：将处理后的数据发送到目标，例如Elasticsearch或Logstash。
8.模块：Filebeat提供了一些预定义的模块，用于简化常见应用程序和服务的日志采集配置。
3. 使用场景
9.集中化日志管理：将多个服务器的日志集中到一个地方，便于统一管理和分析。
10.监控应用程序和系统日志：实时监控和分析应用程序、系统和网络设备的日志信息。
11.安全事件监控：采集和分析安全相关的日志，以检测和响应安全事件。
4. 模块
Filebeat提供了多个预定义的模块，可以简化常见应用程序和服务的日志采集配置。
5. 监控与管理
Filebeat支持与Elastic Stack中的其他工具（如Kibana）集成，以实现日志的可视化和监控。用户可以在Kibana中创建仪表板，以实时查看采集到的日志数据。
结论
Filebeat是一个强大的工具，适合在各种环境中实现高效的日志采集和转发。通过与Elasticsearch和Kibana的结合，Filebeat使用户能够轻松集中和分析日志数据，帮助快速识别和解决问题。
type: log #input类型为log
enable: true #表示是该log类型配置生效
paths： #指定要监控的日志，目前按照Go语言的glob函数处理。没有对配置目录做递归处理，比如配置的如果是：
- /var/log/* /*.log #则只会去/var/log目录的所有子目录中寻找以".log"结尾的文件，而不会寻找/var/log目录下以".log"结尾的文件。
recursive_glob.enabled: #启用全局递归模式，例如/foo/**包括/foo, /foo/*, /foo/*/*
encoding：#指定被监控的文件的编码类型，使用plain和utf-8都是可以处理中文日志的
exclude_lines: ['^DBG'] #不包含匹配正则的行
include_lines: ['^ERR', '^WARN'] #包含匹配正则的行
harvester_buffer_size: 16384 #每个harvester在获取文件时使用的缓冲区的字节大小
max_bytes: 10485760 #单个日志消息可以拥有的最大字节数。max_bytes之后的所有字节都被丢弃而不发送。默认值为10MB (10485760)
exclude_files: ['\.gz$'] #用于匹配希望Filebeat忽略的文件的正则表达式列表
ingore_older: 0 #默认为0，表示禁用，可以配置2h，2m等，注意ignore_older必须大于close_inactive的值.表示忽略超过设置值未更新的
文件或者文件从来没有被harvester收集
close_* #close_ *配置选项用于在特定标准或时间之后关闭harvester。 关闭harvester意味着关闭文件处理程序。 如果在harvester关闭
后文件被更新，则在scan_frequency过后，文件将被重新拾取。 但是，如果在harvester关闭时移动或删除文件，Filebeat将无法再次接收文件
，并且harvester未读取的任何数据都将丢失。
close_inactive #启动选项时，如果在制定时间没有被读取，将关闭文件句柄
读取的最后一条日志定义为下一次读取的起始点，而不是基于文件的修改时间
如果关闭的文件发生变化，一个新的harverster将在scan_frequency运行后被启动
建议至少设置一个大于读取日志频率的值，配置多个prospector来实现针对不同更新速度的日志文件
使用内部时间戳机制，来反映记录日志的读取，每次读取到最后一行日志时开始倒计时使用2h 5m 来表示
close_rename #当选项启动，如果文件被重命名和移动，filebeat关闭文件的处理读取
close_removed #当选项启动，文件被删除时，filebeat关闭文件的处理读取这个选项启动后，必须启动clean_removed
close_eof #适合只写一次日志的文件，然后filebeat关闭文件的处理读取
close_timeout #当选项启动时，filebeat会给每个harvester设置预定义时间，不管这个文件是否被读取，达到设定时间后，将被关闭
close_timeout 不能等于ignore_older,会导致文件更新时，不会被读取如果output一直没有输出日志事件，这个timeout是不会被启动的，
至少要要有一个事件发送，然后haverter将被关闭
设置0 表示不启动
clean_inactived #从注册表文件中删除先前收获的文件的状态
设置必须大于ignore_older+scan_frequency，以确保在文件仍在收集时没有删除任何状态
配置选项有助于减小注册表文件的大小，特别是如果每天都生成大量的新文件
此配置选项也可用于防止在Linux上重用inode的Filebeat问题
clean_removed #启动选项后，如果文件在磁盘上找不到，将从注册表中清除filebeat
如果关闭close removed 必须关闭clean removed
scan_frequency #prospector检查指定用于收获的路径中的新文件的频率,默认10s
tail_files：#如果设置为true，Filebeat从文件尾开始监控文件新增内容，把新增的每一行文件作为一个事件依次发送，
而不是从文件开始处重新发送所有内容。
symlinks：#符号链接选项允许Filebeat除常规文件外,可以收集符号链接。收集符号链接时，即使报告了符号链接的路径，
Filebeat也会打开并读取原始文件。
backoff： #backoff选项指定Filebeat如何积极地抓取新文件进行更新。默认1s，backoff选项定义Filebeat在达到EOF之后
再次检查文件之间等待的时间。
max_backoff： #在达到EOF之后再次检查文件之前Filebeat等待的最长时间
backoff_factor： #指定backoff尝试等待时间几次，默认是2
harvester_limit：#harvester_limit选项限制一个prospector并行启动的harvester数量，直接影响文件打开数tags #列表中添加标签，用过过滤，例如：tags: ["json"]
fields #可选字段，选择额外的字段进行输出可以是标量值，元组，字典等嵌套类型
默认在sub-dictionary位置
filebeat.inputs:
fields:
app_id: query_engine_12
fields_under_root #如果值为ture，那么fields存储在输出文档的顶级位置multiline.pattern #必须匹配的regexp模式
multiline.negate #定义上面的模式匹配条件的动作是 否定的，默认是false
假如模式匹配条件'^b'，默认是false模式，表示讲按照模式匹配进行匹配 将不是以b开头的日志行进行合并
如果是true，表示将不以b开头的日志行进行合并
multiline.match # 指定Filebeat如何将匹配行组合成事件,在之前或者之后，取决于上面所指定的negate
multiline.max_lines #可以组合成一个事件的最大行数，超过将丢弃，默认500
multiline.timeout #定义超时时间，如果开始一个新的事件在超时时间内没有发现匹配，也将发送日志，默认是5smax_procs #设置可以同时执行的最大CPU数。默认值为系统中可用的逻辑CPU的数量。name #为该filebeat指定名字，默认为主机的hostname

多行匹配配置
4种组合设置 以b为中心的， b之前的，b之后的各种不同组合规则，比如 让异常 at开头的都在一行中，而不是分开
异常合并版本：
multiline.pattern: '^[[:space:]]+(at|\.{3})\b|^Caused by:'
multiline.negate: false
multiline.match: after
异常合并版本2（生产环境，Kibana全体倒序排列的时候，一个接口内时间正序，很好）：
multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
multiline.negate: true
multiline.match: after
合并了一个线程的（官方推荐的，合并的有点厉害，这种不行的，合并以后时间都是错乱的）multiline.pattern: '^\['multiline.negate: truemultiline.match: after

坑
1、console一直没成功过，以为是整个有问题，换了另一台linux重新部署还是一样；
2、输出es开始也没成功，最后用最原始filebeat.yml的配置，成功输出到es了，本质还是yml中path那边配置自己项目路径日志有大问题，需要比对案例，空格和格式不能错，一点一点手动写入，不要拷贝；
3、巨坑：filebeat在用nohup和黑洞的方式启动以后，老是自己退出关闭。查找资料是用这个nohup启动以后，必须exit退出以后，再去关闭xshell（这种很容易忘记或者别人误操作，不太好）。还有一种解决办法是加一个配置文件（不太好）。最佳解决办法为nohup命令后面加一个参数。（这个参数将会使启动的nohup进程从当前shell的作业列表中清除，从而避免nohup进程在关闭这个shell时退出）
四、综合理论案例
案例（多虚机ELFK+Redis+TCP）
logstash配置一，后面是逐渐完善的。stdout方便测试输出
logstash配置二
filebeat的redis配置
filebeat的beats配置
tcp那个 是logstash直接读取tcp，所以不用配置filebeat
Kibana直接看到3个索引
