on GitHub

Prelude

Release on: 2021-01-14

• Please refer to the 7.25.0 tag on
  integrations-core
  for the list of changes on the Core Checks

New Features

• Add com.datadoghq.ad.tags container
  auto-discovery label in AWS Fargate environment.
• Package the gstatus command line tool binary for GlusterFS
  integration metric collection.
• Queried domain can be tracked as part of DNS stats
• APM: The agent is now able to skip top-level span computation in
  cases when the client has marked them by means of the
  Datadog-Client-Computed-Top-Level header.
• APM: The maximum allowed key length for tags has been increased from
  100 to 200.
• APM: Improve Oracle SQL obfuscation support.
• APM: Added support for Windows pipes. To enable it, set the pipe
  path using DD_APM_WINDOWS_PIPE_NAME. For more details check PR
  #6615
• Pause containers are now detected and auto excluded based on the
  io.kubernetes container labels.
• APM: new datadog_agent.obfuscate_sql_exec_plan
  function exposed to python checks to enable obfuscation of
  json-encoded SQL Query Execution Plans.
• APM: new obfuscate_sql_values
  option in apm_config.obfuscation
  enabling optional obfuscation of SQL queries contained in JSON data
  collected from some APM services (ES & Mongo)

Enhancement Notes

• Support the ddog-gov.com site option in the Windows GUI installer.
• Adds config setting for ECS metadata endpoint client timeout
  (ecs_metadata_timeout), value in milliseconds.
• Add loader config to allow selecting
  specific loader at runtime. This config is available at init_config and instances level.
• Added additional container information to the status page when
  collect all container logs is enabled in agent status.
• On Windows, it will no longer be required to supply the ddagentuser
  name on upgrade. Previously, if a non-default or domain user was
  used, the same user had to be provided on subsequent upgrades.
• Added --flare flag to agent check to save check results to the
  agent logs directory. This enables flare to pick up check results.
• Added new config option for JMXFetch collect_default_jvm_metrics
  that enables/disables default JVM metric collection.
• Allow empty message for DogStatsD events (e.g. "_e{10,0}:test
  title|")
• Expires the cache key for availability of ECS metadata endpoint used
  to fetch EC2 resource tags every 5 minutes.
• Data coming from kubernetes pods now have new kube_ownerref_kind
  and kube_ownerref_name tags for each of the pod's OwnerRef
  property, indicating its Kind and Name, respectively.
• We improved the way Agents get the Kubernetes cluster ID from the
  Cluster Agent. It used to be that the cluster agent would create a
  configmap which had to be mounted as an env variable in the agent
  daemonset, blocking the process-agent from starting if not found.
  Now the process-agent will start, only the Kubernetes Resources
  collection will be blocked.
• Events sent by the runtime security agent to the backend use a new
  taxonomy.
• Scrub container args as well for orchestrator explorer.
• Support custom autodiscovery identifiers on Kubernetes using the
  ad.datadoghq.com/<container_name>.check.id
  pod annotation.
• The CPU check now collects system-wide context switches on Linux.
• Add --table option to agent check command to output results in
  condensed tabular format instead of JSON.
• APM: improve performance by changing the msgpack serialization
  implementation.
• APM: improve the performance of the msgpack deserialization for the
  v0.5 payload format.
• APM: improve performance of trace processing by removing some heap
  allocations.
• APM: improve sublayer computation performance by reducing the number
  of heap allocations.
• APM: improved stats computation performance by removing some string
  concatenations.
• APM: improved trace signature computation by avoiding heap
  allocations.
• APM: improve stats computation performance.
• Update from alpine:3.10 to alpine:3.12 the base image in Dogstatsd's
  Dockerfiles.

Deprecation Notes

• APM: remove the already deprecated apm_config.extra_aggregators
  config option.

Bug Fixes

• Fix macos dlopen failures by ensuring
  cmake preserves the required runtime search path.
• Fix memory leak on check unscheduling, which could be noticeable for
  checks submitting large amounts of metrics/tags.
• Exclude pause containers using the cdk/pause.* image.
• Fixed missing some Agent environment variables in the flare
• Fix a bug that prevented the logs Agent from discovering the correct
  init containers source and service on Kubernetes.
• The logs agent now uses the container image name as logs source
  instead of kubernetes when a standard
  service value was defined for the container.
• Fixes panic on concurrent map access in Kubernetes metadata tag
  collector.
• Fixed a bug that could potentially cause missing container tags for
  check metrics.
• Fix a potential panic on ECS when the ECS API is returning empty
  docker ID
• Fix systemd check id to handle multiple instances. The fix will make
  check id unique for each different instances.
• Fix missing tags on pods that were not seen with a running container
  yet.
• Fix snmp listener subnet loop to use correct subnet pointer when
  creating snmpJob object.
• Upgrade the embedded pip version to 20.3.3 to get a newer vendored
  version of urllib3.

Other Notes

• The Agent, Logs Agent and the system-probe are now compiled with Go
  1.14.12
• Upgrade embedded libkrb5 Kerberos library to v1.18.3. This version
  drops support for the encryption types marked as "weak" in the docs
  of the
  library
