how to access mesos http endpoints to fetch cluster information

I have a local mesos setup (playa mesos) which is running in my local system. I have a requirement where i need to analyse the resource offering from different slaves and also need to get scheduling information from mesos cluster nodes (master and slaves).

I am trying to using curl for hitting the HTTP endpoints as mentioned in the mesos documentation and try to get the information back. 

 curl --no-buffer -X POST -H "Content-Type: application/json" --data '{"type":"SUBSCRIBE","subscribe":{"framework_info":{"user":"root","name":"democurl"}}}' http://<ip address>:5050/master/api/v1/scheduler

which is returning the offerings from different slaves. Now there are many HTTP endpoints related to scheduling, job execution etc which are not working. When I am trying to access them with curl it's simply not working and not returning any json data back.

I need help to make mesos http end points woking for all available resurces. I am trying to follow mesos documentation but no luck yet.It will be great if some one can post a sample curl command working. thanks

I believe your curl command hitting the "/health" endpoint is working fine; you see nothing at the command-line because the 200 OK response has no body. To see the response headers as well, use the -i option with curl:

~/src/mesos/build|master⚡  curl -i --header "Content-Type: application/json" --header "Accept: application/json" -X GET localhost:5050/master/health
HTTP/1.1 200 OK
Date: Wed, 30 Mar 2016 19:15:45 GMT
Content-Length: 0

~/src/mesos/build|master⚡  curl -i --header "Content-Type: application/json" --header "Accept: application/json" -X GET localhost:5050/master/state
HTTP/1.1 200 OK
Date: Wed, 30 Mar 2016 19:16:54 GMT
Content-Type: application/json
Content-Length: 1504
