When ES is not running under the given port, the plugin currently simply outputs this:

# /usr/lib/nagios/plugins/check_es_system.sh -H "myesnode" -t status
ES SYSTEM UNKNOWN - Authentication required but missing username and password

But using curl itself clearly shows that the connection to port 9200 cannot be established:

# curl http://myesnode:9200/_cluster/stats
curl: (7) Failed to connect to myesnode port 9200: Connection refused

In the plugin we can't see that because we use a silent curl output, however we can use curl's exit status:

# curl -k -s --max-time 30 http://myesnode:9200/_cluster/stats
# echo $?
7
