logstash實作日志檔案同步到elasticsearch深入詳解

引言：

之前博文介紹過了mysql/oracle與ES之間的同步機制。而logstash最初始的日志同步功能還沒有介紹。本文就logstash同步日志到ES做下詳細解讀。

1、目的：

将本地磁盤存儲的日志檔案同步（全量同步、實時增量同步）到ES中。

2、源檔案：

[root@5b9dbaaa148a test_log]# ll
-rwxrwxrwx 1 root root 170 Jul 5 08:02 logmachine.sh
-rw-r--r-- 1 root root 66 Jul 5 08:25 MProbe01.log
-rw-r--r-- 1 root root 74 Jul 5 08:28 MProbe02.log           

3、增量實時同步腳本：

[root@5b9dbaaa148a test_log]# cat logmachine.sh
#!/bin/bash
icnt=0;
while (true)
do
  echo "[debug][20160703-15:00]"$icnt >> MProbe01.log
  echo "[ERROR][20160704-17:00]"$icnt >> MProbe02.log
  icnt=$((icnt+1));
done           

4、logstash配置檔案：

[root@5b9dbaaa148a logstash_jdbc_test]# cat log_test.conf
input {
  file {
  path=> [ "/usr/local/logstash/bin/test_log/MProbe01.log",
"/usr/local/logstash/bin/test_log/MProbe02.log" ]
  #codec=>multiline {
  # pattern => "^\s"
  # what=>"previous"
  #}
  type=>"probe_log"  #類型名稱
  # tags=>["XX.XX.XX.XX"]
  }
}

###過濾
#filter{
# grok {
# match => ["message","mailmonitor"]
# add_tag => [mailmonitor]
# }

# grok {
# match => [ "message", "smsmonitor" ]
# add_tag => [smsmonitor]
# }
# ....
#}

###output to es
output {
  elasticsearch {
  hosts => "10.8.5.101:9200"
  index => "mprobe_index"     #索引名稱
  #template_name => "mprobelog"
  #document_id => "%{id}"
  }
  stdout { codec => json_lines }
}           

5、同步測試：

[root@5b9dbaaa148a bin]# ./logstash -f ./logstash_jdbc_test/log_test.conf
Settings: Default pipeline workers: 24
Pipeline main started
{"message":"[DEbug][20160305-15:35]testing02","@version":"1","@timestamp":"2016-07-05T07:26:08.043Z","path":"/usr/local/logstash/bin/test_log/MProbe01.log","host":"5b9dbaaa148a"           

6、結果驗證

（1）日志記錄：

[root@5b9dbaaa148a test_log]# tail -f MProbe01.log
[DEbug][20160305-15:35]testing02
[DEbug][20160305-15:35]testing01
^C
[root@5b9dbaaa148a test_log]# tail -f MProbe02.log
[DEbug][20160305-15:35]testing02_001
[DEbug][20160305-15:35]testing02_003           

（2）ES記錄
