filebeat配置 (tomcat日志有多行配置)
- input_type: log

# Paths that should be crawled and fetched. Glob based paths.
paths:
- /root/apache/logs/access*
document_type: apache-accesslog

document_type: tomcat-accesslog

有需求来了， elk立功了!!！
elasticdump 迁移与导出es数据

导出搜索匹配 :request":"/redenv_AfterShare.ss 的数据
/root/software/node_modules/elasticdump/bin/elasticdump --input=http://127.0.0.1:9200/logstash-apache-accesslog-2016.12.13 --output=logstash-apache-accesslog-2016.12.13.json --searchBody ‘{"query": {"match":{"request":"/redenv_AfterShare.ss"}}}‘ --type=data --sourceOnly

只导出message
/root/software/node_modules/elasticdump/bin/elasticdump --input=http://127.0.0.1:9200/logstash-apache-accesslog-2016.12.04
--output=/root/software/node_modules/elasticdump/bin/apache_accesslog/logstash-apache-accesslog-2016-12-04.json
