Send Experiment Keep-Alive Signal¶
Send an experiment's keep-alive signal. The response tells the client how often to send the keep-alive signal, and how often to report CPU and GPU usage. Typically, a live experiment requests that the isAliveBeatDurationMillis is around 10 seconds, and an offline experiment requests about 10 minutes. In any event, the return status will send the suggested time intervals. The isAliveBeatDurationMillis determines when an experiment is no longer shown as processing in the frontend GUI.

"gpuMonitorIntervalMillis": 60000,
"isAliveBeatDurationMillis": 10000
