OpenTelemetry Auto Instrumentation using eBPF
google.golang.org/grpc 1.72.0-dev. (#1849)go.opentelemtry.io/auto/pipeline package is added. This package contains interface definitions for types that want to handle the telemetry generated by auto-instrumentation. (#1859)go.opentelemtry.io/auto/pipeline/otelsdk package is added. This package a default handler that uses the OpenTelemetry Go SDK to handle telemetry generated by auto-instrumentation. ()WithHandler function is added to configure Instrumentation in go.opentelemtry.io/auto with the desired handler implementation. (#1859)auto/cli) can now be passed the target process PID directly using the -target-pid CLI option. (#1890)auto/cli) can now be passed the path of the target process executable directly using the -target-exe CLI option. (#1890)auto/cli) now resolves the target PID from the environment variable "OTEL_GO_AUTO_TARGET_PID" if no target options are passed. (#1890)auto/cli) will now only resolve the target process executable from the environment variable "OTEL_GO_AUTO_TARGET_EXE" if no target options are passed and "OTEL_GO_AUTO_TARGET_PID" is not set. (#1890)golang.org/x/net 0.36.0. (#1940)google.golang.org/grpc 1.71.0. (#1940)1.23.7. (#1940)1.24.1. (#1940)go.opentelemetry.io/otel v1.35.0. (#1948)golang.org/x/net 0.37.0. (#1948)golang.org/x/net 0.38.0. (#2063)google.golang.org/grpc 1.71.1. (#2078)1.23.8. (#2081)1.24.2. (#2081)google.golang.org/grpc 1.73.0-dev. (#2091)golang.org/x/net 0.39.0. (#2107)Multiplexer type is added to go.opentelemetry.io/auto/pipeline/otelsdk. This type is used to support multiple process instrumentation using the same telemetry pipeline. (#2016)google.golang.org/grpc 1.72.0. (#2190)golang.org/x/net 0.40.0. (#2281)1.23.9. (#2292)1.24.3. (#2292)github.com/segmentio/kafka-go 0.4.48. (#2319)google.golang.org/grpc 1.71.2. (#2319)google.golang.org/grpc 1.72.1. (#2319)google.golang.org/grpc 1.74.0-dev. (#2337)go.opentelemetry.io/otel v1.36.0. (#2352)WithEnv function no longer parses OTEL_GO_AUTO_GLOBAL. This is included by default. (#1859)WithEnv function no longer parses OTEL_SERVICE_NAME or OTEL_TRACES_EXPORTER. Use the Handler from go.opentelemtry.io/auto/pipeline/otelsdk with its own WithEnv to replace functionality. (#1859)v1.30.0. (#2032)net/http.Request. Now it uses Request.Pattern instead of Request.pat.str unless using go1.22, which continue using Request.pat.str. (#2090)WithGlobal function is removed from go.opentelemtry.io/auto. This option is on by default. (#1859)WithServiceName function is removed from go.opentelemtry.io/auto. Use WithServiceName in go.opentelemtry.io/auto/pipeline/otelsdk along with WithHandler to replace functionality. (#1859)WithTraceExporter function is removed from go.opentelemtry.io/auto. Use WithTraceExporter in go.opentelemtry.io/auto/pipeline/otelsdk along with WithHandler to replace functionality. (#1859)WithResourceAttributes function is removed from go.opentelemtry.io/auto. Use WithResourceAttributes in go.opentelemtry.io/auto/pipeline/otelsdk along with WithHandler to replace functionality. (#1859)"OTEL_GO_AUTO_TARGET_EXE" has been removed from WithEnv.
Note, the built binary (auto/cli) still supports resolution and use of this value.
If using the auto package directly, you will need to resolve this value yourself and pass the discovered process PID using WithPID. (#1890)WithTarget function is removed. The auto package no longer supports process discovery (note: the built binary (auto/cli) still supports process discovery). Once a target process has been identified, use WithPID to configure Instrumentation instead. (#1890)process.runtime.version resource attribute is now the exact value returned from debug to match what OpenTelemetry semantic conventions recommend. (#1985)process.runtime.description to Resource to follow OpenTelemetry semantic conventions. (#1986)kafka-go instrumentation if the kernel does not support bpf_probe_write_user. (#2105)autosdk and otel/trace probes.
