Elasticsearch output Plugin cant send data

Elastic Stack Logstash
4

When the ES output starts, it adds the the URL you specify to an initial list of URLS then it starts sniffing because your config said it should.
During sniffing it queries ES using your URL http://127.0.0.1:9200 using a GET to the _nodes endpoint, it checks the reply by iterating over each node map looking for its http_address key. Any nodes without a value for this key are assumed to "have HTTP disabled" and are skipped.
It then deletes all initial URLS that were not successfully sniffed.

@BADMAN - Questions you need to answer:

  • Do you have an Elasticsearch cluster?
  • If so, what type of nodes do you have in the cluster.
  • if not, disable sniffing and retry.
