Please share how to monitor Logstash from CLI

Elastic Stack Logstash
1

For Example:

In case of Elasticsearch it shows 200 OK,
root@BLR-SOFT-203:~# curl -I http://localhost:9200
HTTP/1.1 200 OK
Content-Type: text/plain; charset=UTF-8
Content-Length: 0

In case of Logstash

curl -XGET http://192.168.17.73:5050
curl: (52) Empty reply from server

Not only curl, is there any way to get the status 200.

Thanks
