1、收集访问日志
1)、首先是要在nginx里面配置日志格式化输出
log_format main "$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" ;
access_log /var/log/nginx/access.log main;
2)、接下来开始在logstash创建处理nginx的配置文件
input {
file {
path => ["/var/log/nginx/access.log"]
}
}
filter {
ruby {
init => "@kname =['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 =>"&"
include_keys => ["uid","cip"]
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"
}
}
output{stdout{}}
此处的例子借鉴ELKstack权威指南里面的例子,不过书中的例子有错,我这里修改好了,可以参考书籍39页和66页

3)、最后允许一下看一下效果所示:
{
"url_path" => "/",
"body_bytes_sent" => 0,
"@version" => "1",
"message" => "- | 05/Mar/2019:16:21:40 +0800 | GET / HTTP/1.1 | 304 | 0 | - | - | - | Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 SE 2.X MetaSr 1.0 |- | 172.16.0.10 | elk-chaofeng07 | - | - | 0.000",
"host" => "ELK-chaofeng07",
"http_COOKIE" => "- ",
"upstream_addr" => " - ",
"upstream_response_time" => 0.0,
"@timestamp" => 2019-03-05T08:21:41.352Z,
"uri" => "/",
"request" => " GET / HTTP/1.1 ",
"path" => "/var/log/nginx/access.log",
"url_args" => nil,
"hostname" => " elk-chaofeng07 ",
"verb" => "HTTP/1.1",
"http_user_agent" => " Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 SE 2.X MetaSr 1.0 ",
"time_local" => " 05/Mar/2019:16:21:40 +0800 ",
"request_body" => " - ",
"remote_addr" => " 172.16.0.10 ",
"status" => " 304 ",
"request_time" => 0.0,
"method" => "GET",
"http_referer" => " - ",
"tags" => [
[0] "_dateparsefailure"
],
"content_length" => 0,
"http_x_forwarded_for" => "- "
}
唯一不足的就是中间报了个错误,可以自行解决一下。
2、收集错误日志
定义logstash处理的配置文件
input{
file {
path => ["/var/log/nginx/error.log"]
}
}
filter{
grok {
match => {"message" => "(?\d\d\d\d/\d\d/\d\d \d\d:\d\d:\d\d) \[(?\w+)\] \S+: \*\d+ (?[^,]+), \w+: %{IP:remotehost}, \w+: \w+, \w+: (?[^,]+), \w+: \"%{IP:localhost}\""}
}
mutate {
remove_field => ["message"]
}
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)
"
}
}
}
output{stdout{}}
查看一下效果:
{
"@version" => "1",
"path" => "/var/log/nginx/error.log",
"remotehost" => "172.16.0.10",
"request" => "\"GET /8 HTTP/1.1\"",
"verb" => "HTTP/1.1\"",
"uri" => "/8",
"host" => "ELK-chaofeng07",
"localhost" => "172.16.0.57",
"method" => "\"GET",
"@timestamp" => 2019-03-05T10:43:54.377Z,
"datetime" => "2019/03/05 18:43:53",
"errormsg" => "open() \"/usr/share/nginx/html/8\" failed (2: No such file or directory)",
"errortype" => "error"
}
