ELK由5.5.x升级到6.0.0的错误及其解决办法收集

一.升级完毕打开Logstash运行日志观察提示如下错误信息：

[2017-12-19T16:30:14,283][WARN
][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"logstash-dev-elastic01-app-2017.11.30", :_type=>"app", :_routing=>nil}, #<LogStash::Event:0x16db134e @data={"@timestamp"=>2017-12-19T16:30:14.267Z,

错误特征：

Kibana无法有效接收到由Elasticsearch传递过来的来自Logstash的日志

错误原因：

Elasticsearch配置中的logstash模板仍在使用5.5.0的旧模板，新版不兼容

解决方法：

1.服务器上使用curl删除旧模板：

curl -XDELETE 'http://10.0.7.227:9200/_template/logstash'

2.接着重启Logstash，自动重新生成适配6.0.0的模板
