Current status -
I am trying to pull all yarn metrics data via curl on the HDP machine that is set up on 2.6.3 on VM
i am trying to run the curl command on the same host machine.
however, my curl command is failing. i tried using hostname and same issue
but curl -v <ip> works.
I want to use this data to plot graphs/ patterns that can reflect the usage of the cluster and suggest improvements.
My curl command -
curl -v "http://192.168.56.101:6188/ws/v1/timeline/metrics?metricNames=bytes_in._rate._avg&hostname=&appId=HO..."
Error message -

Is my port incorrect ? what is the best command to pull yarn metrics .
Has anyone tried working on curl on VM and successfully able to pull data from yarn api
can someone share me any pointers that can be helpful here.
I referred to one of the posts and picked up the command.
