2. Ping request:

We can send a ping request to check the status of the API. 
It uses the REST endpoint GET /xray/api/v1/system/ping to perform the Health Check.
And the ping endpoint responds to requests with a basic 200: Ping successful message.

curl -uadmin:password -XGET http://localhost:8082/xray/api/v1/system/ping

{"status":"pong"}
