Elasticsearch优化 & filebeat配置文件优化 & logstash格式配置 & grok实践

编码转换问题（主要就是中文乱码）

（1）input 中的codec => plain 转码

codec => plain {
         charset => "GB2312"
}

将GB2312 的文本编码，转为UTF-8 的编码java

（2）也能够在filebeat中实现编码的转换（推荐）

filebeat.prospectors:
- input_type: log
  paths:
    - c:\Users\Administrator\Desktop\performanceTrace.txt
  encoding: GB2312

删除多余日志中的多余行

（1）logstash filter 中drop 删除

if ([message] =~ "^20.*-\ task\ request,.*,start\ time.*") {   #用正则需删除的多余行
            drop {}
    }

（2）日志示例

2020-03-20 10:44:01,523 [33]DEBUG Debug - task request,task Id:1cbb72f1-a5ea-4e73-957c-6d20e9e12a7a,start time:2018-03-20 10:43:59   #需删除的行
-- Request String : {"UserName":"15046699923","Pwd":"ZYjyh727","DeviceType":2,"DeviceId":"PC-20170525SADY","EquipmentNo":null,"SSID":"pc","RegisterPhones":null,"AppKey":"ab09d78e3b2c40b789ddfc81674bc24deac","Version":"2.0.5.3"} -- End
-- Response String : {"ErrorCode":0,"Success":true,"ErrorMsg":null,"Result":null,"WaitInterval":30} -- End

grok 处理多种日志不一样的行（重点）

（1）日志示例：react

2020-03-20 10:44:01,523 [33]DEBUG Debug - task request,task Id:1cbb72f1-a5ea-4e73-957c-6d20e9e12a7a,start time:2018-03-20 10:43:59
-- Request String : {"UserName":"15046699923","Pwd":"ZYjyh727","DeviceType":2,"DeviceId":"PC-20170525SADY","EquipmentNo":null,"SSID":"pc","RegisterPhones":null,"AppKey":"ab09d78e3b2c40b789ddfc81674bc24deac","Version":"2.0.5.3"} -- End
-- Response String : {"ErrorCode":0,"Success":true,"ErrorMsg":null,"Result":null,"WaitInterval":30} -- End

在logstash filter中grok 分别处理3行

match => {
    "message" => "^20.*-\ task\ request,.*,start\ time\:%{TIMESTAMP_ISO8601:RequestTime}"
}

match => {
    "message" => "^--\ Request\ String\ :\ \{\"UserName\":\"%{NUMBER:UserName:int}\",\"Pwd\":\"(?<Pwd>.*)\",\"DeviceType\":%{NUMBER:DeviceType:int},\"DeviceId\":\"(?<DeviceId>.*)\",\"EquipmentNo\":(?<EquipmentNo>.*),\"SSID\":(?<SSID>.*),\"RegisterPhones\":(?<RegisterPhones>.*),\"AppKey\":\"(?<AppKey>.*)\",\"Version\":\"(?<Version>.*)\"\}\ --\ \End.*"    
}

match => {
    "message" => "^--\ Response\ String\ :\ \{\"ErrorCode\":%{NUMBER:ErrorCode:int},\"Success\":(?<Success>[a-z]*),\"ErrorMsg\":(?<ErrorMsg>.*),\"Result\":(?<Result>.*),\"WaitInterval\":%{NUMBER:WaitInterval:int}\}\ --\ \End.*"
}

... 等多行

    group_id => "logstash"						# kafka group
    topics => ["test", "filebeat"]				# kafka topics
    codec => json 								# 设定输入类型为json
  }
}

filter {

    }
    
    # 下面这段是为了解决Elasticsearch 默认时间是0时区，不是东八区，因此默认显示时间比东八区少8个小时，这时咱们经过ruby 进行时间格式的修改，增长8个小时，示例以下:
    ruby { 
        code => "event.set('timestamp', event.get('@timestamp').time.localtime + 8*60*60)" 
    }
 
    ruby {
        code => "event.set('@timestamp',event.get('timestamp'))"
    }

日志多行合并处理—multiline插件（重点）

（1）示例：ios

① 日志golang

2018-03-20 10:44:01,523 [33]DEBUG Debug - task request,task Id:1cbb72f1-a5ea-4e73-957c-6d20e9e12a7a,start time:2018-03-20 10:43:59
-- Request String : {"UserName":"15046699923","Pwd":"ZYjyh727","DeviceType":2,"DeviceId":"PC-20170525SADY","EquipmentNo":null,"SSID":"pc","RegisterPhones":null,"AppKey":"ab09d78e3b2c40b789ddfc81674bc24deac","Version":"2.0.5.3"} -- End
-- Response String : {"ErrorCode":0,"Success":true,"ErrorMsg":null,"Result":null,"WaitInterval":30} -- End

② logstash grok 对合并后多行的处理（合并多行后续都同样，以下）web

filter {
　　grok {
　　　　match => {
　　　　　　"message" => "^%{TIMESTAMP_ISO8601:InsertTime}\ .*-\ task\ request,.*,start\ time:%{TIMESTAMP_ISO8601:RequestTime}\n--\ Request\ String\ :\ \{\"UserName\":\"%{NUMBER:UserName:int}\",\"Pwd\":\"(?<Pwd>.*)\",\"DeviceType\":%{NUMBER:DeviceType:int},\"DeviceId\":\"(?<DeviceId>.*)\",\"EquipmentNo\":(?<EquipmentNo>.*),\"SSID\":(?<SSID>.*),\"RegisterPhones\":(?<RegisterPhones>.*),\"AppKey\":\"(?<AppKey>.*)\",\"Version\":\"(?<Version>.*)\"\}\ --\ \End\n--\ Response\ String\ :\ \{\"ErrorCode\":%{NUMBER:ErrorCode:int},\"Success\":(?<Success>[a-z]*),\"ErrorMsg\":(?<ErrorMsg>.*),\"Result\":(?<Result>.*),\"WaitInterval\":%{NUMBER:WaitInterval:int}\}\ --\ \End"
　　　　}
　　}
}

（2）在filebeat中使用multiline 插件（推荐）正则表达式

① 介绍multilineredis

pattern：正则匹配从哪行合并spring

negate：true/false，匹配到pattern 部分开始合并，仍是不配到的合并json

match：after/before（需本身理解）

　　after：匹配到pattern 部分后合并，注意：这种状况最后一行日志不会被匹配处理

　　before：匹配到pattern 部分前合并（推荐）

② 5.5版本以后（before为例）

filebeat.prospectors:
- input_type: log
  paths:
    - /root/performanceTrace*
  fields:
    type: zidonghualog
  multiline.pattern: '.*\"WaitInterval\":.*--\ End'
  multiline.negate: true
  multiline.match: before

③ 5.5版本以前（after为例）

filebeat.prospectors:
- input_type: log 
     paths:
      - /root/performanceTrace*
      input_type: log 
      multiline:
           pattern: '^20.*'
           negate: true
           match: after

（3）在logstash input中使用multiline 插件（没有filebeat 时推荐）

① 介绍multiline

pattern：正则匹配从哪行合并

negate：true/false，匹配到pattern 部分开始合并，仍是不配到的合并

what：previous/next（需本身理解）

　　previous：至关于filebeat 的after

　　next：至关于filebeat 的before

② 用法

input {
        file {
                path => ["/root/logs/log2"]
                start_position => "beginning"
                codec => multiline {
                        pattern => "^20.*"
                        negate => true
                        what => "previous"
                }
        }
}

（4）在logstash filter中使用multiline 插件（不推荐）

（a）不推荐的缘由：

　　① filter设置multiline后，pipline worker会自动将为1

　　② 5.5 版本官方把multiline 去除了，要使用的话需下载，下载命令以下：

　　/usr/share/logstash/bin/logstash-plugin install logstash-filter-multiline

（b）示例：

filter {
  multiline {
    pattern => "^20.*"
    negate => true
    what => "previous"
  }
}

logstash filter 中的date使用

（1）日志示例

2018-03-20 10:44:01 [33]DEBUG Debug - task request,task Id:1cbb72f1-a5ea-4e73-957c-6d20e9e12a7a,start time:2018-03-20 10:43:59

（2） date 使用

date {
                match => ["InsertTime","YYYY-MM-dd HH:mm:ss "]
                remove_field => "InsertTime"
        }

注：

match => ["timestamp" ,"dd/MMM/YYYY H:m:s Z"]

匹配这个字段，字段的格式为：日日/月月月/年年年年时/分/秒时区

也能够写为：match => ["timestamp","ISO8601"]（推荐）

（3）date 介绍

　　就是将匹配日志中时间的key 替换为@timestamp 的时间，由于@timestamp 的时间是日志送到logstash 的时间，并非日志中真正的时间。

六、对多类日志分类处理（重点）

① 在filebeat 的配置中添加type 分类

filebeat:
  prospectors:
    - paths:
        - /mnt/data_total/WebApiDebugLog.txt*
      fields:
        type: WebApiDebugLog_total
    - paths:
        - /mnt/data_request/WebApiDebugLog.txt*
      fields:
        type: WebApiDebugLog_request
    - paths:
        - /mnt/data_report/WebApiDebugLog.txt*
      fields:
        type: WebApiDebugLog_report

② 在logstash filter中使用if，可进行对不一样类进行不一样处理

filter {
   if [fields][type] == "WebApiDebugLog_request" {   #对request 类日志
        if ([message] =~ "^20.*-\ task\ report,.*,start\ time.*") {   #删除report 行
                drop {}
        }
    grok {
        match => {"... ..."}
        }
}

③ 在logstash output中使用if

if [fields][type] == "WebApiDebugLog_total" {
    elasticsearch {
        hosts => ["6.6.6.6:9200"]
        index => "logstashl-WebApiDebugLog_total-%{+YYYY.MM.dd}"
        document_type => "WebApiDebugLog_total_logs"
}

对elk 总体性能的优化

性能分析

（1）服务器硬件Linux：1cpu 4GRAM

假设每条日志250 Byte

（2）分析

① logstash硬件Linux：1cpu 4GRAM

每秒500条日志

去掉ruby每秒660条日志

去掉grok后每秒1000条数据

② filebeat硬件Linux：1cpu 4GRAM

每秒2500-3500条数据

天天每台机器可处理：24h*60min*60sec*3000*250Byte=64,800,000,000Bytes，约64G

③ 瓶颈在logstash 从redis中取数据存入ES，开启一个logstash，每秒约处理6000条数据；开启两个logstash，每秒约处理10000条数据（cpu已基本跑满）；

④ logstash的启动过程占用大量系统资源，由于脚本中要检查java、ruby以及其余环境变量，启动后资源占用会恢复到正常状态。

关于收集日志的选择：logstash/filter

（1）没有原则要求使用filebeat或logstash，二者做为shipper的功能是同样的，区别在于：

① logstash因为集成了众多插件，如grok，ruby，因此相比beat是重量级的；

② logstash启动后占用资源更多，若是硬件资源足够则无需考虑两者差别；

③ logstash基于JVM，支持跨平台；而beat使用golang编写，AIX不支持；

④ AIX 64bit平台上须要安装jdk（jre） 1.7 32bit，64bit的不支持；

⑤ filebeat能够直接输入到ES，可是系统中存在logstash直接输入到ES的状况，这将形成不一样的索引类型形成检索复杂，最好统一输入到els 的源。

（2）总结

　　logstash/filter 总之各有千秋，可是，我推荐选择：在每一个须要收集的日志服务器上配置filebeat，由于轻量级，用于收集日志；再统一输出给logstash，作对日志的处理；最后统一由logstash 输出给es。中间也开增长kafka消息队列进行缓存。

logstash的优化相关配置

（1）能够优化的参数，可根据本身的硬件进行优化配置

① pipeline 线程数，官方建议是等于CPU内核数

默认配置 ---> pipeline.workers: 2

可优化为 ---> pipeline.workers: CPU内核数（或几倍cpu内核数）

② 实际output 时的线程数

默认配置 ---> pipeline.output.workers: 1

可优化为 ---> pipeline.output.workers: 不超过pipeline 线程数

③ 每次发送的事件数

默认配置 ---> pipeline.batch.size: 125

可优化为 ---> pipeline.batch.size: 1000

④ 发送延时

默认配置 ---> pipeline.batch.delay: 5

可优化为 ---> pipeline.batch.size: 10

（2）总结

　　经过设置-w参数指定pipeline worker数量，也可直接修改配置文件logstash.yml。这会提升filter和output的线程数，若是须要的话，将其设置为cpu核心数的几倍是安全的，线程在I/O上是空闲的。

　　默认每一个输出在一个pipeline worker线程上活动，能够在输出output 中设置workers设置，不要将该值设置大于pipeline worker数。

　　还能够设置输出的batch_size数，例如ES输出与batch size一致。

　　filter设置multiline后，pipline worker会自动将为1，若是使用filebeat，建议在beat中就使用multiline，若是使用logstash做为shipper，建议在input 中设置multiline，不要在filter中设置multiline。

（3）Logstash中的JVM配置文件

　　Logstash是一个基于Java开发的程序，须要运行在JVM中，能够经过配置jvm.options来针对JVM进行设定。好比内存的最大最小、垃圾清理机制等等。JVM的内存分配不能太大不能过小，太大会拖慢操做系统。过小致使没法启动。默认以下：

-Xms256m  # 最小使用内存
-Xmx1g 	  # 最大使用内存

引入Redis 的相关问题

（1）filebeat能够直接输入到logstash（indexer），但logstash没有存储功能，若是须要重启须要先停全部连入的beat，再停logstash，形成运维麻烦；另外若是logstash发生异常则会丢失数据；引入Redis做为数据缓冲池，当logstash异常中止后能够从Redis的客户端看到数据缓存在Redis中；

（2）Redis可使用list(最长支持4,294,967,295条)或发布订阅存储模式；

（3）redis 作elk 缓冲队列的优化：

① bind 0.0.0.0 #不要监听本地端口

② requirepass ilinux.io #加密码，为了安全运行

③ 只作队列，不必持久存储，把全部持久化功能关掉：快照（RDB文件）和追加式文件（AOF文件），性能更好

　　save "" 禁用快照
　　appendonly no 关闭RDB

④ 把内存的淘汰策略关掉，把内存空间最大

　　maxmemory 0 #maxmemory为0的时候表示咱们对Redis的内存使用没有限制

elasticsearch 节点优化配置

（1）服务器硬件配置，OS 参数

（a） /etc/sysctl.conf 配置

vim /etc/sysctl.conf

vm.swappiness = 1                     # ES 推荐将此参数设置为 1，大幅下降 swap 分区的大小，强制最大程度的使用内存，注意，这里不要设置为 0, 这会极可能会形成 OOM
net.core.somaxconn = 65535     		# 定义了每一个端口最大的监听队列的长度
vm.max_map_count= 262144    			# 限制一个进程能够拥有的VMA(虚拟内存区域)的数量。虚拟内存区域是一个连续的虚拟地址空间区域。当VMA 的数量超过这个值，OOM
fs.file-max = 518144                  # 设置 Linux 内核分配的文件句柄的最大数量

[root@elasticsearch]# sysctl -p 生效一下

（b）limits.conf 配置

vim /etc/security/limits.conf
elasticsearch    soft    nofile          65535
elasticsearch    hard    nofile          65535
elasticsearch    soft    memlock         unlimited
elasticsearch    hard    memlock         unlimited

（c）为了使以上参数永久生效，还要设置两个地方

vim /etc/pam.d/common-session-noninteractive
vim /etc/pam.d/common-session

添加以下属性：
session required pam_limits.so
可能需重启后生效

（2）elasticsearch 中的JVM配置文件

-Xms2g
-Xmx2g

① 将最小堆大小（Xms）和最大堆大小（Xmx）设置为彼此相等。

② Elasticsearch可用的堆越多，可用于缓存的内存就越多。但请注意，太多的堆可能会使您长时间垃圾收集暂停。

③ 设置Xmx为不超过物理RAM的50％，以确保有足够的物理内存留给内核文件系统缓存。

④ 不要设置Xmx为JVM用于压缩对象指针的临界值以上；确切的截止值有所不一样，但接近32 GB。不要超过32G，若是空间大，多跑几个实例，不要让一个实例太大内存

（3）elasticsearch 配置文件优化参数

① vim elasticsearch.yml

bootstrap.memory_lock: true  #锁住内存，不使用swap
#缓存、线程等优化以下
bootstrap.mlockall: true
transport.tcp.compress: true
indices.fielddata.cache.size: 40%
indices.cache.filter.size: 30%
indices.cache.filter.terms.size: 1024mb
threadpool:
    search:
        type: cached
        size: 100
        queue_size: 2000

② 设置环境变量

vim /etc/profile.d/elasticsearch.sh export ES_HEAP_SIZE=2g #Heap Size不超过物理内存的一半，且小于32G

（4）集群的优化（我未使用集群）

① ES是分布式存储，当设置一样的cluster.name后会自动发现并加入集群；

② 集群会自动选举一个master，当master宕机后从新选举；

③ 为防止"脑裂"，集群中个数最好为奇数个

④ 为有效管理节点，可关闭广播 discovery.zen.ping.multicast.enabled: false，并设置单播节点组discovery.zen.ping.unicast.hosts: ["ip1", "ip2", "ip3"]

性能的检查

（1）检查输入和输出的性能

Logstash和其链接的服务运行速度一致，它能够和输入、输出的速度同样快。

（2）检查系统参数

① CPU

注意CPU是否过载。在Linux/Unix系统中可使用top -H查看进程参数以及总计。

若是CPU使用太高，直接跳到检查JVM堆的章节并检查Logstash worker设置。

② Memory

注意Logstash是运行在Java虚拟机中的，因此它只会用到你分配给它的最大内存。

检查其余应用使用大量内存的状况，这将形成Logstash使用硬盘swap，这种状况会在应用占用内存超出物理内存范围时。

③ I/O 监控磁盘I/O检查磁盘饱和度

使用Logstash plugin（例如使用文件输出）磁盘会发生饱和。

当发生大量错误，Logstash生成大量错误日志时磁盘也会发生饱和。

在Linux中，可以使用iostat，dstat或者其余命令监控磁盘I/O

④ 监控网络I/O

当使用大量网络操做的input、output时，会致使网络饱和。

在Linux中可以使用dstat或iftop监控网络状况。

（3）检查JVM heap

heap设置过小会致使CPU使用率太高，这是由于JVM的垃圾回收机制致使的。

一个快速检查该设置的方法是将heap设置为两倍大小而后检测性能改进。不要将heap设置超过物理内存大小，保留至少1G内存给操做系统和其余进程。

你可使用相似jmap命令行或VisualVM更加精确的计算JVM heap
