引言：
之前博文介绍过了mysql/oracle与ES之间的同步机制。而logstash最初始的日志同步功能还没有介绍。本文就logstash同步日志到ES做下详细解读。
1、目的：
将本地磁盘存储的日志文件同步（全量同步、实时增量同步）到ES中。
2、源文件：
[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、增量实时同步脚本：
[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配置文件：
[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" #类型名称
# tags=>["XX.XX.XX.XX"]
}
}
###过滤
#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" #索引名称
#template_name => "mprobelog"
#document_id => "%{id}"
}
stdout { codec => json_lines }
}
5、同步测试：
[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、结果验证
（1）日志记录：
[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记录
