收集nginx日志

初级版

第一步: nginx配置json日志格式

log_format json '{ "time_local": "$time_local", '
                           '"remote_addr": "$remote_addr", '
                           '"referer": "$http_referer", '
                           '"request": "$request", '
                           '"status": $status, '
                           '"bytes": $body_bytes_sent, '
                           '"agent": "$http_user_agent", '
                           '"x_forwarded": "$http_x_forwarded_for", '
                           '"up_addr": "$upstream_addr",'
                           '"up_host": "$upstream_http_host",'
                           '"upstream_time": "$upstream_response_time",'
                           '"request_time": "$request_time"'
    ' }';
access_log  /var/log/nginx/access.log json;

vim /etc/nginx/nginx.conf

第二步: filebeat配置

配置json解析

json.keys_under: true
json.overwrite_keys: true

配置自定义索引名字

output.elasticsearch:
  hosts: ["172.16.240.60:9200"]
  index: "nginx-%{[beat.version]}-%{+yyyy.MM}"
setup.template.name: "nginx"
setup.template.pattern: "nginx-*"
setup.template.enabled: false

vim /etc/filebeat/filebeat.yml

systemctl restart filebeat

第三步: 清空nginx日志, 重启nginx, 删除原nginx日志产生的索引

清空nginx日志, 重启nginx

>/var/log/nginx/access.log
systemctl restart nginx

删除原nginx日志产生的索引

产生一些日志

ab -n 1000 -c 100 http://172.16.240.80/

进阶版

收集错误日志, 并且通过2个索引来分别存储错误日志和正确日志

第一步: filebeat配置

filebeat.inputs:

- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
  tags: ["access"]
  json.keys_under: true
  json.overwrite_keys: true

- type: log
  enabled: true
  paths:
    - /var/log/nginx/error.log 
  
  tags: ["error"]
  json.keys_under: true
  json.overwrite_keys: true
  
output.elasticsearch:
  hosts: ["172.16.240.60:9200"]
  #index: "nginx-%{[beat.version]}-%{+yyyy.MM}"
  indices:
    - index: "access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "access"
    - index: "error-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "error"

参考官方文档 :

https://www.elastic.co/guide/en/beats/filebeat/6.6/filebeat-input-log.html

https://www.elastic.co/guide/en/beats/filebeat/6.6/elasticsearch-output.html

vim /etc/filebeat/filebeat.yml

systemctl restart filebeat.service

第二步:

第三步: 清空nginx日志, 重启nginx, 删除原nginx日志产生的索引

清空nginx日志, 重启nginx

>/var/log/nginx/access.log
systemctl restart nginx

删除原nginx日志产生的索引

产生一些日志

ab -n 1000 -c 100 http://172.16.240.80/
ab -n 100 -c 100 http://172.16.240.80/lyysb

收集tomcat日志

第一步: 配置tomcat 的json日志格式

pattern="{&quot;clientip&quot;:&quot;%h&quot;,&quot;ClientUser&quot;:&quot;%l&quot;,&quot;authenticated&quot;:&quot;%u&quot;,&quot;AccessTime&quot;:&quot;%t&quot;,&quot;method&quot;:&quot;%r&quot;,&quot;status&quot;:&quot;%s&quot;,&quot;SendBytes&quot;:&quot;%b&quot;,&quot;Query?string&quot;:&quot;%q&quot;,&quot;partner&quot;:&quot;%{Referer}i&quot;,&quot;AgentVersion&quot;:&quot;%{User-Agent}i&quot;}"

vim /etc/tomcat/server.xml

为了验证方便, 清空tomcat日志

> /var/log/tomcat/localhost_access_log.2020-01-21.txt

systemctl restart tomcat

查看tomcat日志

tail -f /var/log/tomcat/localhost_access_log.2020-01-21.txt

第二步: 配置filebeat

vim /etc/filebeat/filebeat.yml

systemctl restart filebeat.service

验证是否数据是否存入elasticsearch

收集elasticsearch日志

参考文档

https://www.elastic.co/guide/en/beats/filebeat/6.6/multiline-examples.html

第一步: 配置filebeat

vim /etc/filebeat/filebeat.yml

systemctl restart filebeat.service

第二步: 制造elasticsearch错误日志

将配置文件改错重启elasticsearch, 然后改回来再重启elasticsearch

vim /etc/elasticsearch/elasticsearch.yml

重启服务

systemctl restart elasticsearch.service

再把配置文件改回来, 重启服务

vim /etc/elasticsearch/elasticsearch.yml

systemctl restart elasticsearch.service

查看elasticsearch日志

tail -f /var/log/elasticsearch/elasticsearch.log

第三步: 查看结果

打开 kibana http://172.16.240.70:5601/
