Discussion

RSpace team is looking for ways to optimize calculations for throughput (produce and consume)
- Currently using --diagnostics
- Going forward idea to more appropriately use Kamon and Prometheus to collect and report metrics
We have the flag --diagnostics in node
- Diagnostics was not intended to be used for performance metrics
- IDEA to remove --diagnostics flag (ticket)
Clarification - Goal is to move calculation of metrics out of RSpace
Discussion about using either spans or histograms for measuring events
- For measuring throughput we need to measure events across time and attached to a point in time
- Recommendation to use timestamp counters
Idea if Prometheus does not provide the requisite granularity, consider StatsD
Requirements
- Today we need:
  - baseline measure of throughput
- In future we can iterate to include:
  - Throughput
  - Peak
