New metrics on the API dashboard

The API dashboard in Helios now also displays a few new metrics on the top right, calculated based on instrumented data during that time range and in the specific environment:

  1. Total number of calls, and throughput (requests per minute)
  2. Total number of errors, and error rate (erroneous calls out of total calls)
  3. Average duration
API monitoring metrics

API metrics calculated based on distributed tracing data appear in the API dashboard

Note that all the metrics are subject to sampling - they are counted based on sampled data.
