DataDog/datadog-agent 7.21.0

on GitHub

Prelude

Release on: 2020-07-16

• Please refer to the 7.21.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• APM: The maximum allowed payload size by the agent was increased
  from 10MB to 50MB. This could result in traffic increases for users
  which were affected by this issue.
• APM: The maximum connection limit over a 30s period was removed.
  This can result in an increase of tracing data for users that were
  affected by this limitation.

New Features

• Add support of new DatadogMetric CRD in DCA. Allows to autoscale
  based on any valid Datadog query.
• Add packages scripts for dogstatsd that have the same features as
  the agent: create symlink for binary, create dd-agent user and
  group, setup the service and cleanup those when uninstalling.
• Adds OOM Kill probe to ebpf package and corresponding corecheck to
  the agent.
• The Datadog IoT Agent is now available for 32 bit ARM architecture
  (armv7l/armhf).
• Add Compliance agent in Cluster Agent to monitor Kubernetes objects
• Add docker.cpu.limit and containerd.cpu.limit metrics, reporting
  maximum cpu time (hz or ns) available for each container based on
  their limits. (Only supported on Linux)
• Addition of a gRPC server and a hostname resolution endpoint,
  including a grpc-gateway that exposes said endpoint as a REST
  service.
• Adding a 'log_format_rfc3339' option to use the RFC3339 format for
  the log time.
• Compliance Agent implementing scheduling of compliance checks for
  Docker and Kubernetes benchmarks.
• Expose agent's sql obfuscation to python checks via new
  datadog_agent.obfuscate_sql method
• Support installing non-core integrations with the integration
  command, such as those located in the integrations-extras
  repository.

Enhancement Notes

• The Agent status command now includes the flavor of the Agent that
  is running.
• The Agent GUI now includes the flavor of the Agent that is running.
• Adds Tagger information to Datadog Agent flare for support
  investigations.
• Add a static collector in the tagger package for tags that do not
  change after pod start (such as those from an environment variable).
• Add autodiscovery_subnet to available SNMP template extra configs
• When enabling collect_ec2_tags or collect_gce_tags option,
  EC2/GCE tags are now cached to avoid missing tags when user exceed
  his AWS/GCE quotas.
• Chocolatey package can be installed on Domain Controller
• The Agent now collects the Availability Zone a Fargate Task (using
  platform version 1.4 or later) is running in as an
  "availability_zone" tag.
• Enabled the collection of the init-containers by bumping the
  agent-payload dep. and collecting the init-containers.
• The Agent now collects recommended "app.kubernetes.io" Kubernetes
  labels as tags by default, and exposes them under a "kube_app"
  prefix.
• Docker and Containerd checks now support filtering containers by
  kube_namespace.
• Add support for sampling to distribution metrics
• Flare now includes the permission information for parents of config
  and log file directories.
• Collect processes namespaced PID.
• You can now enable or disable the dogstatsd-stats troubleshooting
  feature at runtime using the config set dogstatsd_stats command of
  the Agent.
• API Keys are now sanitized for logs_config and
  additional_endpoints.
• Upgrade gosnmp to support more authentication and privacy protocols
  for v3 connections.
• Use the standard tag 'service' as a log collection attribute for
  container's logs collected from both kubernetes and docker log
  sources.
• agent check returns non zero exit code when trace malloc is enabled
  (tracemalloc_debug: true) when using python 2
• Added the checksum type to the checksum key itself, as it is
  deprecated to have a separate checksum_type key.
• Add lowercase_device_tag option to the system io core check on
  Windows. When enabled, sends metrics with a lowercased device tag,
  which is consistent with the system.io.* metrics of Agent v5 and
  the system.disk.* metrics of all Agent versions.

Bug Fixes

• Fix missing values from cluster-agent status command.

• Add missing device_name tag in iostats_pdh

• Fixes an issue where DD_TAGS were not applied to EKS Fargate pods
  and containers.

• Add freetds linux dep needed for SQL Server to run in Docker
  Agent.

• APM : Fix parsing of non-ASCII numerals in the SQL obfuscator.
  Previously unicode characters for which unicode.IsDigit returns true
  could cause a hang in the SQL obfuscator

• APM: correctly obfuscate AUTH command.

• Dogstatsd standalone: when running on a systemd-based system, do not
  stop Dogstatsd when journald is stopped or restarted.

• Fix missing logs and metrics for docker-labels based autodiscovery
  configs after container restart.

• Fix bugs introduced in 7.20.0/6.20.0 in the Agent 5 configuration
  import command: the command would not import some Agent config
  settings, including api_key, and would write some Docker &
  Kubernetes config settings to wrongly-located files.

• Fixes tag extraction from Kubernetes pod labels when using patterns
  on certain non-alphanumeric label names (e.g.
  app.kubernetes.io/managed-by).

• Fixes the /ready health endpoint on the cluster-agent.

  The /ready health endpoint was reporting 200 at the cluster-agent
  startup and was then, permanently reporting 500 even though the
  cluster-agent was experiencing no problem. In the body of the
  response, we could see that a healthcheck component was failing.
  This change fixes this issue.

• This fix aims to cover the case when the agent is running inside GKE
  with workload identity enabled. If workload identity is enabled,
  access to /instance/name is forbidden, resulting into an empty host
  alias.

• Fix hostname resolution issue preventing the Process and APM agents
  from picking up a valid hostname on some containerized environments

• Fix a bug which causes certain configuration options to be ignored
  by the process-agent in the presence of a system-probe.yaml.

• Process agent and system probe now correctly accept multiple API
  keys per endpoint.

• The device_name tag is not used anymore to populate the Device
  field of a series. Only the device tag is considered.

• Fixes problem on Windows where ddagentuser home directory is left
  behind.

• Revert upgrade of GoSNMP and addition of extra authentication
  protocols.

• Add support for examining processes inside Docker containers running
  under systemd cgroups. This also reduces agent logging volume as
  it's able to capture those statistics going forward.

• APM: The agent now exits with code 0 when the API key is not
  specified. This is so to prevent the Windows SCM from restarting the
  process.

Other Notes

• All Agents binaries are now compiled with Go 1.13.11.
• In Debug mode, DogStatsD log a warning message when a burst of
  metrics is detected.
• JMXFetch upgraded to
  0.38.0
• JQuery, used in the web-based agent GUI, has been upgraded to 3.5.1
