Elasticsearch generates lots of Suricate events

I've setup an ELK stack to parse Suricate log events, but I'm having a problem with Elasticsearch generating too much data. Every few seconds, it generates several log events such as

{"timestamp":"2015-12-20T04:56:07.588866","event_type":"fileinfo","src_ip":"127.0.0.1","src_port":40901,"dest_ip":"127.0.0.1","dest_port":9200,"proto":"TCP","http":{"url":"/_bulk","hostname":"localhost","http_user_agent":"Manticore 0.4.4"},"fileinfo":{"filename":"/_bulk","magic":"ASCII text, with very long lines","state":"CLOSED","stored":false,"size":3898}}
{"timestamp":"2015-12-20T04:56:07.599335","event_type":"http","src_ip":"127.0.0.1","src_port":40901,"dest_ip":"127.0.0.1","dest_port":9200,"proto":"TCP","http":{"hostname":"localhost","url":"/_bulk","http_user_agent":"Manticore 0.4.4","accept_encoding":"gzip,deflate"}}

I'm not sure how to suppress this information. Thoughts?

The only way to suppress it is to not send it to ES.
You could put LS in the mix and then filter these out.
