@ES报错

欢迎使用Markdown编辑器

`[ERROR][logstash.outputs.elasticsearch] Attempted to send a bulk request to elasticsearch, but no there are no living connections in the connection pool. Perhaps Elasticsearch is unreachable or down? {:message=>“No Available connections”, “exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::NoConnectionAvailableError”, :will_retry_in_seconds=>64}

解决办法

1. 查看conf文件是否配置用户名和密码
2. 发现querry 和delete 但是 get报错，经排查索引空间满了，需要清理空间再运行程序。
