ELK--使用redis与logstash结合收集数据

kibana

kibana

是为elasticsearch提供web可视化界面，为用户提供数据展示

kibana安装

[root\@kibana \~]# ls

1. anaconda-ks.cfg GeoLite2-City.tar.gz kibana-7.1.1-x86_64.rpm

2. [root\@kibana \~]# yum -y install kibana-7.1.1-x86_64.rpm

修改kibana配置文件

#开启端口

#设置侦听端口

#设置elasticsearch主机#设置语言，不用汉化

[root\@kibana \~]# cat /etc/kibana/kibana.yml | grep -v "#" | grep -v "\^\$"
server.port: 5601

server.host: "192.168.122.10"

elasticsearch.hosts: ["http://192.168.122.20:9200","http://192.168.122.30:9200"]
i18n.locale: "zh-CN"

启动服务

1 # systemctl start kibana;systemctl enable kibana;systemctl status kibana

使用?lebeat与redis结合收集数据

1 #在web服务器上使用filebeat收集日志 2

3 ## cat /etc/filebeat/filebeat.yml

4 ###################### Filebeat Configuration
Example ######################### 5

1. # This file is an example configuration file highlighting only the most
   common

2. # options. The filebeat.reference.yml file from the same directory contains
   all the

3. # supported options with more comments. You can use it as a reference. 9 #

4. # You can find the full configuration reference here:

5. #
   https://www.elastic.co/guide/en/beats/filebeat/index.html
   12

6. # For more available modules and options, please see the
   filebeat.reference.yml sample

7. # configuration file. 15

   16 #========================== Filebeat inputs

17

18 filebeat.inputs:

19

8. # Each - is an input. Most options can be set at the input level, so

9. # you can use different inputs for various configurations.

10. # Below are the input specific configurations. 23

    24 - type: log 25

11. # Change to true to enable this input configuration.

12. enabled: true 28

13. # Paths that should be crawled and fetched. Glob based paths.

14. paths:

15. - /var/log/nginx/access.log

16. #- c:\programdata\elasticsearch\logs\* 33

17. # Exclude lines. A list of regular expressions to match. It drops the lines
    that are

18. # matching any regular expression from the list.

19. #exclude_lines: [‘\^DBG‘] 37

20. # Include lines. A list of regular expressions to match. It exports the
    lines that are

21. # matching any regular expression from the list.

22. #include_lines: [‘\^ERR‘, ‘\^WARN‘] 41

23. # Exclude files. A list of regular expressions to match. Filebeat drops the
    files that

24. # are matching any regular expression from the list. By default, no files
    are dropped.

25. #exclude_files: [‘.gz\$‘] 45

26. # Optional additional fields. These fields can be freely picked

27. # to add additional information to the crawled log files for filtering

28. #fields:

29. # level: debug

30. # review: 1 51

    52 ### Multiline options 53

31. # Multiline can be used for log messages spanning multiple lines. This is
    common

32. # for Java Stack Traces or C-Line Continuation 56

33. # The regexp Pattern that has to be matched. The example pattern matches
    all lines starting with [

34. #multiline.pattern: \^\[ 59

35. # Defines if the pattern set under pattern should be negated or not.
    Default is false.

36. #multiline.negate: false 62

37. # Match can be set to "after" or "before". It is used to define if lines
    should be append to a pattern

38. # that was (not) matched before or after or as long as a pattern is not
    matched based on negate.

39. # Note: After is the equivalent to previous and before is the equivalent to
    to next in Logstash

40. #multiline.match: after 67

    104 #============================== Dashboards

19. # These settings control loading the sample dashboards to the Kibana index.

22. #setup.dashboards.enabled: false 109

23. # The URL from where to download the dashboards archive. By default this

    released

25. # versions, this URL points to the dashboard archive on the
    artifacts.elastic.co

26. # website.

27. #setup.dashboards.url:

28. 116 #============================== Kibana

117

29. # Starting with Beats version 6.0.0, the dashboards are loaded via the
    Kibana API.

30. # This requires a Kibana endpoint configuration.

31. setup.kibana:

134

135 # These settings simplify using filebeat with the Elastic Cloud
(https://cloud.elastic.co/).

136

42. # The cloud.id setting overwrites the `output.elasticsearch.hosts` and

44. # You can find the `cloud.id` in the Elastic Cloud web UI.

45. #cloud.id:
