我有一个“ElasticSearch - Logstash - Kibana”部署，其中一个logstash实例通过专用的ElasticSearch客户端将数据推送到ElasticSearch集群。该集群具有3个Data-Master节点和一个专用客户端节点。所有机器都有64 GB RAM，32 Core，2TB Disk＆amp;运行Debian 8。
我在logstash日志中看到"Failed action with response of 400, dropping action"发出了很多警告。在elasticsearch日志中，我看到相应的错误为failed to execute bulk item (index) index。这不是每次都发生的事。
logstash输出配置如下： -
output {
elasticsearch {
index => "jab-%{env}-%{app}-%{iver}-%{[@metadata][app_log_time]}"
cluster => "elasticsearch"
host => "es-client"
port => "9300"
protocol => "transport"
}
file {
path => "/var/log/shop/%{env}/%{app}/%{app}_%{host}_%{[@metadata][app_log_time]}.log"
}
}
弹性搜索的完整登录如下： -

有人可以让我知道出了什么问题吗？如何调试？
