v1.61.0

Summary

In this release, Application Performance Monitoring (APM) adds support for Span Links (a highly requested feature!). This feature is currently supported within Datadog's OpenTelemetry API implementation.

The default trace context propagation order, which is used for traces in distributed workflows, will become datadog,tracecontext (previously it was tracecontext,datadog). This is not a breaking change, and customers should not experience any negative changes in behavior. If you experience any issues, please reach out to Datadog support.

Other APM features include out-of-the-box library integration support for github.com/jackc/pgx/v5 and the ability to ignore specific error types in the github.com/labstack/echo/v4 integration.

Changes

Application Performance Monitoring (APM)

Application Security Management (ASM)

ASM Customers upgrading to Go 1.22 should upgrade dd-trace-go or at least upgrade github.com/DataDog/go-libddwaf to version v2.3.1. Otherwise ASM Threats won't start with the following error:

appsec: threats detection cannot be enabled for the following reasons: 1 error occurred:
	* unsupported Go version: go1.22.0

Summary

In this release, Application Performance Monitoring (APM) adds tracing instrumentation support for valyala/fasthttp. This release also fixes a bug with beta-level remote configuration of the tracer, ensuring that config deletion triggers reverting the configuration option to its original value. Startup logs will also be expanded to describe configured feature flags.

This release also adds Beta support for resource-based and tag-based sampling. This can be configured using the new trace SamplingRule called TagResourceRule or by setting "resource" or "tags" in the trace sampling rules JSON, e.g. DD_TRACE_SAMPLING_RULES=[{"service": "test.?", "resource": "ec2.*", "tags": {"aws.operation":"DescribeInstances"}, "sample_rate": 1.0}]

Application Security Management (ASM) adds support for Threat Monitoring on GraphQL operations, and trusted IPs can now be added to your ASM passlist.

The Profiler add the WithCustomProfilerLabelKeys API, which enables using profiler labels as attributes to filter flame graphs in the Continuous Profiler UI. The Profiler also improves execution trace coverage over time for apps which are deployed simultaneously across several instances, by randomizing when execution traces are collected. An execution trace is collected on average once every 15 minutes by default, but the time between execution traces is now randomized.

Highlights

Important Information

⚠️ Starting with this release, dd-trace-go requires libdl.so.21 and libm.so.6 to be present in the deployment environment (except Windows, where Application Security Management is not supported). This should be the case for the vast majority of environments (e.g: Redhat, Debian, Alpine, Amazon Linux, Ubuntu) but might not be the case in some minimal-footprint environments (e.g: BusyBox, docker images from scratch). In situations when these requirements aren't met, you might see errors similar to (the exact error may be slightly different depending on the platform):

  • If ld.so is missing (the environment is unable to load dynamic executables) or is not the expected flavor (the binary was built on one platform, and runs on another which uses a different interpreter): 
    exec /path/to/binary: no such file or directory
  • When one of the required shared libraries is missing (libdl.so.2 in this example): 
    /path/to/binary: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory

If this happens, please create a GitHub issue so we can reconsider this new default requirement. In the meantime, you can work around the problem by adding the datadog.no_waf build tag (go build -tags='datadog.no_waf' ...), which completely disables all Application Security Management features and removes these new requirements.

Application Security Management (ASM) Remote Activation

Application Security Management (ASM) can now be remotely activated by APM Tracing users via Datadog Remote Configuration, granted that the application was built either:

  • with CGO enabled;
  • with CGO_ENABLED=0 and with the appsec build tag (this setup already required libdl.so.21 and libm.so.6 to be present in the deployment environment on previous releases — this remains true).

Remote activation can be performed from different places in Datadog UI, such as ASM's Service Setup or APM's Service Catalog (hovering the ASM Status column).

ASM features can still be enabled locally using the DD_APPSEC_ENABLED=1 environment variable.

Setting the datadog.no_waf build tag completely disables all ASM features, removing the ability for local as well as remote activation.

Application Performance Monitoring (APM)

This release includes a fix to several library integrations which could have previously caused data races related to start options. This was fixed in database/sql, gin-gonic/gin, go-chi/chi.v5, go-chi/chi, google.golang.org/grpc.v12, google.golang.org/grpc, gorilla/mux, julienschmidt/httprouter, k8s.io/client-go/kubernetes, labstack/echo.v4, labstack/echo, net/http, and urfave/negroni. We recommend you update to this version if you are using any of these integrations.

Beta: In-app APM library configuration of trace sampling rate, HTTP header tags and custom tags.
This feature has a known bug: deleting the configuration entry in-app won't reset the configuration locally, this will be fixed in the next version of dd-trace-go (v1.60.0).

What's Changed

This was fixed in database/sql, gin-gonic/gin, go-chi/chi.v5, go-chi/chi, google.golang.org/grpc.v12, google.golang.org/grpc, gorilla/mux, julienschmidt/httprouter, k8s.io/client-go/kubernetes, labstack/echo.v4, labstack/echo, net/http, and urfave/negroni. We recommend you update to this version if you are using any of these integrations.

Application Security Management (ASM) now can be remotely activated by APM Tracing users with Datadog Remote Configuration, without requiring the appsec build tag or DD_APPSEC_ENABLED environment variable. This can be achieved from different places in our UI such as ASM's Service Setup or APM's Service Catalog (hovering the ASM Status column). Non-remote-configuration users still need to deploy their services with the DD_APPSEC_ENABLED opt-in environment variable to enable ASM. Users of CGO_ENABLED=0 will still have to rely on the appsec build tag for now, as it results into a dependency to libdl.so.2 to have on your deployment environment in this precise case, but not when CGO_ENABLED=1.
This release also includes the latest ASM private beta feature, API Security (public documentation still in progress).

Beta: In-app APM library configuration of trace sampling rate, HTTP header tags and custom tags.
This feature has a known bug: deleting the configuration entry in-app won't reset the configuration locally, this will be fixed in the next version of dd-trace-go (v1.60.0).
