Prelude

Release on: 2022-07-25

New Features

  • Add NetFlow feature to listen to NetFlow traffic and forward them to Datadog.
  • The CWS agent now supports filtering events depending on whether they are performed by a thread. A process is considered a thread if it's a child process that hasn't executed another program.
  • Adds a diagnose datadog-connectivity command that displays information about connectivity issues between the Agent and Datadog intake.
  • Adds support for tailing modes in the journald logs tailer.
  • The CWS agent now supports writing rules on processes termination.
  • Add support for new types of CI Visibility payloads to the Trace Agent, so features that until now were Agentless-only are available as well when using the Agent.

Enhancement Notes

  • Tags configured with DD_TAGS or DD_EXTRA_TAGS in an EKS Fargate environment are now attached to OTLP metrics.
  • Add NetFlow static enrichments (TCP flags, IP Protocol, EtherType, and more).
  • Report lines matched by auto multiline detection as metrics and show on the status page.
  • Add a containerd_exclude_namespaces configuration option for the Agent to ignore containers from specific containerd namespaces.
  • The log_level of the agent is now appended to the flare archive name upon its creation.
  • The metrics reported by KSM core now include the tags "kube_app_name", "kube_app_instance", and so on, if they're related to a Kubernetes entity that has a standard label like "app.kubernetes.io/name", "app.kubernetes.io/instance", etc.
  • The Kubernetes State Metrics Core check now collects two ingress metrics: kubernetes_state.ingress.count and kubernetes_state.ingress.path.
  • Move process chunking code to util package to avoid cycle import when using it in orchestrator check.
  • APM: Add support for PostgreSQL JSON operators in the SQL obfuscate package.
  • The OTLP ingest endpoint now supports the same settings and protocol as the OpenTelemetry Collector OTLP receiver v0.54.0 (OTLP v0.18.0).
  • The Agent now embeds Python-3.8.13, an upgrade from Python-3.8.11.
  • APM: Updated Rare Sampler default configuration values to sample traces more uniformly across environments and services.
  • The OTLP ingest endpoint now supports Exponential Histograms with delta aggregation temporality.
  • The Windows installer now supports grouped Managed Service Accounts.
  • Enable https monitoring on arm64 with kernel >= 5.5.0.
  • Add otlp_config.debug.loglevel to determine log level when the OTLP Agent receives metrics/traces for debugging use cases.

Deprecation Notes

  • Deprecateotlp_config.metrics.instrumentation_library_metadata_as_tags in in favor of otlp_config.metrics.instrumentation_scope_metadata_as_tags.

Bug Fixes

  • When enable_payloads.series or enable_payloads.sketches are set to false, don't log the error Cannot append a metric in a closed buffered channel.
  • Restrict permissions for the entrypoint executables of the Dockerfiles.
  • Revert docker.mem.in_use calculation to use RSS Memory instead of total memory.
  • Add missing telemetry metrics for HTTP log bytes sent.
  • Fix panic in container, containerd, and docker when container stats are temporarily not available
  • Fix prometheus check Metrics parsing by not enforcing a list of strings.
  • Fix potential deadlock when shutting down an Agent with a log TCP listener.
  • APM: Fixed trace rare sampler's oversampling behavior. With this fix, the rare sampler will sample rare traces more accurately.
  • Fix journald byte count on the status page.
  • APM: Fixes an issue where certain (#> and #>>) PostgreSQL JSON operators were being interpreted as comments and removed by the obfuscate package.
  • Scrubs HTTP Bearer tokens out of log output
  • Fixed the triggered "svType != tvType; key=containerd_namespace, st=[]interface {}, tt=[]string, sv=[], tv=[]" error when using a secret backend reader.
  • Fixed an issue that made the container check to show an error in the "agent status" output when it was working properly but there were no containers deployed.
