HStream Metrics

Table of metrics, and for usage, please refer to Monitoring chapter.

Note: For metrics with intervals, such as stats in categories like stream and subscription, users can specify intervals (default intervals [1min, 5min, 10min]). The smaller the interval, the closer it gets to the rate in real-time.
