Need Clarity of HPO REST APIs

[Kay-Rohit]

Hi, I am trying the kruize HPO and a little confused with the API bodies, especially with the results endpoint-

'POST /experiment_trials'
'Content-Type: application/json'

url -H 'Content-Type: application/json' http://<URL>:<PORT>/experiment_trials -d 
‘{
    "experiment_name" : "name",
    "operation" : "EXP_TRIAL_RESULT",
    "trial_number": xyz,
    "trial_result": "success | failure | error",
    "result_value_type": "double",
    "result_value": abc
}’

wanted to know what exactly is the "result_value"
If I run tests on jmeter

Since my search space is same as per your api docs, I wanted to know whether this "result_value" is for single tunable, and if yes, is this avg, min, max ?

Thanks,
Rohit
