Changes

• Runtime metrics are publicly available. They can be enabled by setting the DD_RUNTIME_METRICS_ENABLED environment variable to 1. For more information: https://docs.datadoghq.com/tracing/runtime_metrics/dotnet/

• Changes in the trace buffering logic (#1151) :

  • Traces are now serialized as soon as possible, instead of every second. This reduces the lifetime of Span objects, which in turn should decrease the number of gen 1/2 garbage collections
  • Whenever adding a trace would cause the buffer to overflow, the contents are immediately flushed. This should reduce the number of dropped traces for customers with a very large amount of spans

• Optimizations in the native profiler (#1224, #1217, #1215)

• Duck-typing: rename typing cast methods to better reflect the intent (#1220), and add a DuckIgnore attribute (#1257)

• Disable log rate limit when debug logging is enabled (#1239)

• CallTarget instrumentation:

  • Add support for Redis (#1230)
  • Add support for GraphQL (#1241)
  • Add support for MongoDB (#1214)
  • Add support for ASP.NET MVC and WebAPI (#1208)
  • Add support for CurlHandler (#1252)
  • Add support for Elasticsearch (#1248)
  • Add support for RabbitMQ (#1186)
  • Add support for WCF (#1272)
  • Refactor HttpMessageHandler-based instrumentations (#1258) and enable them by default (#1277)
  • Add fast-path for integrations with 7 or 8 parameters (#1261)
  • Enable inlining by default (#1276)
  • Change log severity (#1278)

• Various changes to CI integration (#1242, #1247, #1251, #1244)

Fixes

• Fix some log messages (#1240)
• Status was incorrectly reported for NUnit tests with no assertions (#1235)

• Calltarget:
  • Don't call FindMemberRef when the signature is empty (#1259)
