metrics

Supports observability best-practices

TODO:

• Metrics Tag Context
  • Implemented like Request Context
  • Should support "global tags" (also like Request Context)
• HTTP package
  • HTTP Tax Context Provider
  • HTTP Controller Wrapper for timings?
• Config Enhancements
  • Default tags (which feed into Tag Context Global Tags)
  • Metric name prefix
• Utilize metrics from DataStores/Drivers/Caching
  • For Drivers, it'll be indirect, via http client middleware
• Base Engine that simplifies using Logging and Metrics
  • Just so that engines aren't a special case - Drivers/DataStores/Caching will do it for you
  • (unrelated project, but inspired by / depends on Metrics)
• OperationTracker
  • Should be configurable
    • Ability to enable/disable recording of Count and/or Result metrics since DataDog tracks a count for timers, and since tagging will have the result
