Nginx教程
Nginx日志统计展示
本文主要是介绍Nginx日志统计展示，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
一、 效果展示
二、流程
三、 Nginx 配置
nginx.conf，修改日志格式，指定需要收集的字段及字段分割
http{
........
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent"';
........
}
四、 Filebeat 配置
修改filebeat.yml
egrep -v "^#|^ #|^$" filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/xxx.log
fields:
file_type: nginx-log
fields_under_root: true
encoding: utf-8
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 1
setup.kibana:
output.logstash:
hosts: ["xxx.xxx.xxx.xxx:xxxxx"]
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
- add_docker_metadata: ~
- add_kubernetes_metadata: ~
五、 Logstash 配置
安装geoip插件
./bin/logstash-plugin install logstash-filter-geoip
修改logstash.conf
input {
beats {
host => '0.0.0.0'
port => xxxxx
codec => plain{ charset => "GBK" }
}
}
filter {
if [file_type] == "nginx-log"{
grok {
match => [
'message', '%{IPORHOST:remote_addr} - %{NOTSPACE:remote_user} \[%{HTTPDATE:time_local}\] \"%{WORD:method} %{NOTSPACE:request_uri} %{URIPROTO:proto}/%{NUMBER:httpversion}\" %{NUMBER:status} (?:%{NUMBER:size}|-) %{QS:referrer} %{QS:user_agent}'
]
}
geoip {
source => "remote_addr"
fields => ["location","country_name","city_name","region_name"]
}
mutate {
remove_field => ["host", "agent"]
}
}
}
output {
if [file_type] == "nginx-log"{
elasticsearch {
hosts => ["xxx.xxx.xxx.xxx:xxxxx"]
index => "%{file_type}-%{+YYYY.MM.dd}"
user => 'xxxx'
password => 'xxxxxx'
}
}
}
六、 Elasticsearch 配置
没有需要特别配置的，保证运行正常就行
七、 Grafana 添加数据源
八、 Json导出（只展示panels）
