Hi,

We just followed [Head plugin unable to connect to Elasticsearch 5.3 - cluster health: not connected](https://discuss.elastic.co/t/head-plugin-unable-to-connect-to-elasticsearch-5-3-cluster-health-not-connected/83327/3) to install head plugin by  
./elasticsearch -plugin install x-pack,t when we access localhost:9200/\_plugin/head with userid: elastic and passpwrd: changeme, the error messages are as follows:

{"error":{"root\_cause":[{"type":"illegal\_argument\_exception","reason":"No endpoint or operation is available at [head]"}],"type":"illegal\_argument\_exception","reason":"No endpoint or operation is available at [head]"},"status":400}

Any advice would be appreciated

Head can not be installed as a plugin.

Xpack is something else.

Why not just using kibana dev console?
