我正在尝试使用Logstash解析nginx日志,一切看起来都很好,除了使用包含Nginx $ remote_user的行获取此_grokparsefailure
标记。当$ remote_user为' - '(没有指定$ remote_user时的默认值),Logstash会完成这项工作,但是如果{true}用user@gmail.com
这个真正的$ remote_user失败了并放了一个_grokparsefailure
标记:
127.0.0.1 - - [17 / Feb / 2017:23:14:08 +0100]“GET /favicon.ico HTTP / 1.1”302 169“http://training-hub.tn/trainer/”“Mozilla / 5.0(X11; Linux x86_64)AppleWebKit / 537.36(KHTML,与Gecko一样)Chrome / 56.0.2924.87 Safari浏览器/ 537.36"
=====>工作正常

=====> _grokparsefailure
标记并且无法解析日志行
我正在使用此配置文件:
input {
file {
path => "/home/dev/node/training-hub/logs/access_log"
start_position => "beginning"
sincedb_path => "/dev/null"
ignore_older => 0
type => "logs"
}
}
filter {
if[type] == "logs" {
mutate {
gsub => ["message", "::ffff:", ""]
}
grok {
match=> [
"message" , "%{COMBINEDAPACHELOG}+%{GREEDYDATA:extra_fields}",
"message" , "%{COMMONAPACHELOG}+%{GREEDYDATA:extra_fields}"
]
overwrite=> [ "message" ]
}
mutate {
convert=> ["response", "integer"]
convert=> ["bytes", "integer"]
convert=> ["responsetime", "float"]
}
geoip {
source => "clientip"
target => "geoip"
database => "/etc/logstash/GeoLite2-City.mmdb"
add_field => [ "[geoip][coordinates]", "%{[geoip][longitude]}" ]
add_field => [ "[geoip][coordinates]", "%{[geoip][latitude]}" ]
}
mutate {
convert => [ "[geoip][coordinates]", "float"]
}
date {
match=> [ "timestamp", "dd/MMM/YYYY:HH:mm:ss Z" ]
remove_field=> [ "timestamp" ]
}
useragent {
source=> "agent"
}
}
}
output { elasticsearch { hosts => "localhost:9200" } }
答案 0 :(得分:0)
使用多个值测试输出后,我意识到Logstash无法解析包含此类$remote_user
的日志行,因为它不是有效的用户名(电子邮件地址)所以我添加了mutate gsub
过滤器删除@和邮件地址的其余部分以使其有效$remote_user
。
gsub => [“信息”, “@ + A-Z0-9(:( ?:一个-Z0-9?)|?[(:( ?: 25 [0-5] | 2 [0-4] [0-9] | [01] [0-9] [0-9])){3}(?: 25 [0-5] |?2 [0-4] [0-9] | [01] - [O- ?9] [0-9] | [A-Z0-9 - ] * [A-Z0-9]:(:[\ x01- \ X08 \ X0B \ X0C \ x0e- \ X1F \ x21- \ X5A \ x53- \ 0x7F部分] | \ [\ x01- \ X09 \ X0B \ X0C \ x0e- \ 0x7F部分])+)]) [“,”[“]
现在,它运作良好
