1 Kibana的显示配置
https://demo.elastic.co/app/kibana#/dashboard/welcome_dashboard
环境先处理干净
安装nginx和httpd-tools
2 使用压测工具产生日志
[root@node4 ~]# ab -n 100 -c 100 http://192.168.132.134/

3 安装filebeat
[root@node4 src]# wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.5.1-x86_64.rpm
[root@node4 src]# rpm -ivh filebeat-7.5.1-x86_64.rpm
[root@node4 src]# rpm -qc filebeat
[root@node4 src]# cd /etc/filebeat/
[root@node4 filebeat]# cp filebeat.yml /opt/
[root@node4 filebeat]# grep -Ev "^$|[#;]" filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /usr/local/nginx/logs/access.log
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 1
setup.kibana:
output.elasticsearch:
hosts: ["192.168.132.131:9200","192.168.132.132:9200","192.168.132.133:9200"]
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
- add_docker_metadata: ~
- add_kubernetes_metadata: ~
[root@node4 filebeat]# systemctl restart filebeat
使用kibana查看
访问：http://192.168.132.131:5601/app/kibana
对于一些基本的操作，再前面的学习中已经演示，参看前面的学习实验
4 配置nginx的日志改为json格式
log_format access_json '{"@timestamp":"$time_iso8601",'
'"host":"$server_addr",'
'"clientip":"$remote_addr",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"upstreamtime":"$upstream_response_time",'
'"upstreamhost":"$upstream_addr",'
'"http_host":"$host",'
'"url":"$uri",'
'"domain":"$host",'
'"xff":"$http_x_forwarded_for",'
'"referer":"$http_referer",'
'"status":"$status"}';
添加日志格式
访问后
{"@timestamp":"2020-01-18T23:33:57-05:00","host":"192.168.132.134","clientip":"192.168.132.1","size":0,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.132.134","url":"/index.html","domain":"192.168.132.134","xff":"-","referer":"-","status":"304"}
安装jq工具
[root@node4 filebeat]# yum -y install jq
[root@node4 ~]# tail -f /usr/local/nginx/logs/access.log |jq .
但是读取的依然是整个的message日志
5 filebeat解析成json格式
[root@node4 ~]# grep -Ev "^$|[#;]" /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /usr/local/nginx/logs/access.log
json.key_under_root: true
json.overwrite_keys: true
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 1
setup.kibana:
output.elasticsearch:
hosts: ["192.168.132.131:9200","192.168.132.132:9200","192.168.132.133:9200"]
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
- add_docker_metadata: ~
- add_kubernetes_metadata: ~
[root@node4 ~]# systemctl restart filebeat
得到格式的日志
