filbeat发送监控数据到es报错

根据官方教程monitoring-internal-collection.html,进行了配置,通过kibana的监控页面,提示有收到数据的报错
 

Monitoring 请求错误

[illegal_argument_exception] Fielddata is disabled on text fields by default. Set fielddata=true on [beats_stats.beat.type] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.: 检查 Elasticsearch Monitoring 集群网络连接或节点的负载水平
 
按理说应该es应该是把接收到的filebeat数据存放在某个index中,我没创建这个index,关键是官方教程中也没说明怎么创建index.
