2. 前言less
2.1. 現狀elasticsearch
之前,查看日誌都是經過SSH客戶端登服務器去看,使用較多的命令就是 less 或者 tail。若是服務部署了好幾臺,就要分別登陸到這幾臺機器上看,還要注意日誌打印的時間(好比,有可能一個操做過來產生好的日誌,這些日誌還不是在同一臺機器上,此時就須要根據時間的前後順序推斷用戶的操做行爲,就要在這些機器上來回切換)。並且,搜索的時候不方便,必須對vi,less這樣的命令很熟悉,還容易看花了眼。爲了簡化日誌檢索的操做,能夠將日誌收集並索引,這樣方便多了,用過Lucene的人應該知道,這種檢索效率是很高的。基本上每一個互聯網公司都會有本身的日誌管理平臺和監控平臺(好比,Zabbix),不管是本身搭建的,仍是用的阿里雲這樣的雲服務提供的,反正確定有。下面,咱們利用ELK搭建一個相對真實的日誌管理平臺。ide
2.2. 日誌格式
咱們的日誌,如今是這樣的:
每條日誌的格式,相似於這樣:
2018-08-22 00:34:51.952 [INFO ] [org.springframework.kafka.KafkaListenerEndpointContainer#0-1-C-1] [com.cjs.handler.MessageHandler][39] - 監聽到註冊事件消息:
2.3. logback.xml
2.4. 環境介紹
在本例中,各個系統的日誌都在/data/logs/${projectName},好比:
Filebeat,Logstash,Elasticsearch,Kibana都在一臺虛擬機上,並且都是單實例,並且沒有別的中間件
因爲,日誌天天都會歸檔,且實時日誌都是輸出在info.log或者error.log中,因此Filebeat採集的時候只須要監視這兩個文件便可。
3. Filebeat配置
Filebeat的主要配置在於filebeat.yml配置文件中的 filebeat.inputs 和 output.logstash 區域:
#=========================== Filebeat inputs ============================= filebeat.inputs: - type: log enabled: true # 要抓取的文件路徑 paths: - /data/logs/oh-coupon/info.log - /data/logs/oh-coupon/error.log # 添加額外的字段 fields: log_source: oh-coupon fields_under_root: true # 多行處理 # 不以"yyyy-MM-dd"這種日期開始的行與前一行合併 multiline.pattern: ^\d{4}-\d{1,2}-\d{1,2} multiline.negate: true multiline.match: after # 5秒鐘掃描一次以檢查文件更新 scan_frequency: 5s # 若是文件1小時都沒有更新,則關閉文件句柄 close_inactive: 1h # 忽略24小時前的文件 #ignore_older: 24h - type: log enabled: true paths: - /data/logs/oh-promotion/info.log - /data/logs/oh-promotion/error.log fields: log_source: oh-promotion fields_under_root: true multiline.pattern: ^\d{4}-\d{1,2}-\d{1,2} multiline.negate: true multiline.match: after scan_frequency: 5s close_inactive: 1h ignore_older: 24h #================================ Outputs ===================================== #-------------------------- Elasticsearch output ------------------------------ #output.elasticsearch: # Array of hosts to connect to. # hosts: ["localhost:9200"] # Optional protocol and basic auth credentials. #protocol: "https" #username: "elastic" #password: "changeme" #----------------------------- Logstash output -------------------------------- output.logstash: # The Logstash hosts hosts: ["localhost:5044"] # Optional SSL. By default is off. # List of root certificates for HTTPS server verifications #ssl.certificate_authorities: ["/etc/pki/root/ca.pem"] # Certificate for SSL client authentication #ssl.certificate: "/etc/pki/client/cert.pem" # Client Certificate Key #ssl.key: "/etc/pki/client/cert.key"
4. Logstash配置
4.1. logstash.yml
# X-Pack Monitoring # https://www.elastic.co/guide/en/logstash/current/monitoring-logstash.html xpack.monitoring.enabled: true xpack.monitoring.elasticsearch.username: "logstash_system" xpack.monitoring.elasticsearch.password: "123456" xpack.monitoring.elasticsearch.url: ["http://localhost:9200"]
4.2. 管道配置
input { beats { port => "5044" } } filter { grok { match => { "message" => "%{TIMESTAMP_ISO8601:log_date}\s+\[%{LOGLEVEL:log_level}" } } date { match => ["log_date", "yyyy-MM-dd HH:mm:ss.SSS"] target => "@timestamp" } } output { if [log_source] == "oh-coupon" { elasticsearch { hosts => [ "localhost:9200" ] index => "oh-coupon-%{+YYYY.MM.dd}" user => "logstash_internal" password => "123456" } } if [log_source] == "oh-promotion" { elasticsearch { hosts => [ "localhost:9200" ] index => "oh-promotion-%{+YYYY.MM.dd}" user => "logstash_internal" password => "123456" } } }
4.3. 插件
Logstash針對輸入、過濾、輸出都有好多插件
關於Logstash的插件在以前的文章中不曾說起,由於都是配置,因此不打算再單獨寫一篇了,這裏稍微重點的提一下,下面幾篇文章對此特別有幫助:
https://www.elastic.co/guide/en/logstash/current/input-plugins.html
https://www.elastic.co/guide/en/logstash/current/plugins-inputs-beats.html
https://www.elastic.co/guide/en/logstash/current/plugins-inputs-kafka.html
https://www.elastic.co/guide/en/logstash/current/filebeat-modules.html
https://www.elastic.co/guide/en/logstash/current/output-plugins.html
https://www.elastic.co/guide/en/logstash/current/logstash-config-for-filebeat-modules.html
https://www.elastic.co/guide/en/logstash/current/filter-plugins.html
本例中,到了輸入插件:beats,過濾插件:grok和date,輸出插件:elasticsearch
這裏,最最重要的是 grok ,利用這個插件咱們能夠從消息中提取一些咱們想要的字段
grok

5. Elasticsearch配置

xpack.security.enabled: true
其它均爲默認
6. Kibana配置
