* feat: rate-limit Jaeger UDP messages The Jaeger UDP protocol provides no way to signal backpressure / overload. In certain situations, we are emitting that many tracing spans in a short period of time that the OS, the network, or Jaeger drop them. While a rate limit is not a perfect solution, it for sure helps a lot (tested locally). Note that the limiter does NOT lead to unlimited buffering because we already have a limited outbox queue in place (see `trace_exporters::export::CHANNEL_SIZE`). Fixes #5446. * fix: only warn ones when the tracing channel is full Co-authored-by: kodiakhq[bot] <49736102+kodiakhq[bot]@users.noreply.github.com> |

Regenerating Jaeger Thrift
The instructions below use docker, but this is optional.
Depending on your setup there may be permissions complications that require using-u
Startup a Debian bullseye image
docker run -it -v $PWD:/out debian:bullseye-slim
Install the thrift-compiler
$ apt-get update
$ apt-get install thrift-compiler wget
Verify the version of the compiler matches the version of thrift in Cargo.toml
$ thrift --version
Thrift version 0.13.0
Get the IDL definition
$ wget https://raw.githubusercontent.com/jaegertracing/jaeger-idl/master/thrift/jaeger.thrift https://raw.githubusercontent.com/jaegertracing/jaeger-idl/master/thrift/zipkincore.thrift https://raw.githubusercontent.com/jaegertracing/jaeger-idl/master/thrift/agent.thrift
Generate the code
$ thrift --out /out/src/thrift --gen rs agent.thrift
$ thrift --out /out/src/thrift --gen rs jaeger.thrift
$ thrift --out /out/src/thrift --gen rs zipkincore.thrift
Patch up imports
sed -i 's/use jaeger;/use super::jaeger;/g' /out/src/thrift/agent.rs
sed -i 's/use zipkincore;/use super::zipkincore;/g' /out/src/thrift/agent.rs
