elasticsearch - 流利的配置来解析auth.log

Question

我正在使用以下配置来流利地读取auth.logs并将其发送到 flex 搜索，但是我遇到一个错误，指出模式不匹配并且日志未推送到ES。

我正在使用fluentd syslog解析器插件rfc3164-pattern中定义的模式

<source>
  @type tail
  path /var/log/auth.log
  pos_file /var/log/auth.pos
  format /^\<(?<pri>[0-9]+)\>(?<time>[^ ]* {1,2}[^ ]* [^ ]*) (?<host>[^ ]*) (?<ident>[a-zA-Z0-9_\/\.\-]*)(?:\[(?<pid>[0-9]+)\]) *(?<message>.*)$/
  tag authlog
</source>
<match authlog.**>
  @type elasticsearch
  hosts "ESHOST:PORT"
  logstash_format true
  logstash_prefix "server-authlogs"
  include_tag_key true
  flush_interval 5s
  logstash_dateformat %Y.%m.%d
  time_precision 3
</match>

输出错误:

2019-04-16 08:00:50 +0000 [warn]: #0 pattern not match: "Apr 16 08:00:50 hostname-1415 sshd[15134]: pam_unix(sshd:session): session opened for user ubuntu by (uid=0)" 2019-04-16 08:00:50 +0000 [warn]: #0 pattern not match: "Apr 16 08:00:50 hostname-1415 systemd-logind[1138]: New session 10 of user ubuntu."

对于那些正在寻找类似内容的人，这里的配置很好用。

<source> 
 type tail 
 path /var/log/foo/auth.log 
 pos_file /var/log/auth.pos 
 tag authlog
 format /^(?<time>[^ ]* {1,2}[^ ]* [^ ]*) (?<host>[^ ]*) (?<ident>[a-zA-Z0-9_\/\.\-]*)(?:\[(?<pid>[0-9]+)\])?(?:[^\:]*\:)? *(?<message>.*)$/ 
</source>
<match authlog.**>
 @type elasticsearch
 hosts "ESHOST:PORT"
 logstash_format true
 logstash_prefix "server-authlogs"
 include_tag_key true
 flush_interval 5s
 logstash_dateformat %Y.%m.%d
 time_precision 3
</match>

对于auth.log模式:

Apr 16 18:02:02 host-1415 sshd[11111]: Accepted password for ubuntu from 111.11.111.11 port 11111 ssh2
