ELK如何分析nginx access日志,相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。
注意:修改配置后建议重新创建index
1、nginx 日志文件格式
log_format elk "$http_clientip | $http_x_forwarded_for | $time_local | $request | $status | $body_bytes_sent | "
"$request_body | $content_length | $http_referer | $http_user_agent | "
"$http_COOKIE | $remote_addr | $hostname | $upstream_addr | $upstream_response_time | $request_time";
2、logstash nginx 服务器上的配置文件 agent.conf
input {
file {
type => "elk_frontend_access"
path => ["/data/logs/flight1-access_log"]
}
}
filter {
ruby {
init => "@kname = ['http_clientip','http_x_forwarded_for','time_local','request','status','body_bytes_sent','request_body','content_length','http_referer','http_user_agent','http_COOKIE','remote_addr','hostname','upstream_addr','upstream_response_time','request_time']"
code => "new_event = LogStash::Event.new(Hash[@kname.zip(event.get('message').split('|'))])
new_event.remove('@timestamp')
event.append(new_event)"
}
if [request] {
ruby {
init => "@kname = ['method','uri','verb']"
code => "new_event = LogStash::Event.new(Hash[@kname.zip(event.get('request').split(' '))])
new_event.remove('@timestamp')
event.append(new_event)
"
}
if [uri] {
ruby {
init => "@kname = ['url_path','url_args']"
code => "new_event = LogStash::Event.new(Hash[@kname.zip(event.get('uri').split('?'))])
new_event.remove('@timestamp')
event.append(new_event)
"
}
kv {
prefix => "url_"
source => "url_args"
field_split => "& "
remove_field => [ "url_args","uri","request" ]
}
}
}
mutate {
convert => ["body_bytes_sent" , "integer", "content_length", "integer", "upstream_response_time", "float","request_time", "float"]
}
date {
match => [ "time_local", "dd/MMM/yyyy:hh:mm:ss Z" ]
locale => "en"
}
grok {
match => { "message" => "%{IP:clientip}" }
}
geoip
{
source => "clientip"
}
}
output {
redis {
host => "10.10.45.200"
data_type => "list"
key => "elk_frontend_access:redis"
port=>"5379"
}
}
3、logstash elk服务器上的配置文件server.conf
input {
redis {
host => "10.10.45.200"
data_type => "list"
key => "elk_frontend_access:redis"
port =>"5379"
}
}
output {
elasticsearch {
hosts => "10.10.45.200:8200"
index => "logstash-zjzc-frontend-%{+YYYY.MM.dd}"
}
stdout {
codec => rubydebug
}
}
注意:如果修改后没有生效,在kibana上重建索引。
