DataDog/datadog-agent 7.36.0

on GitHub

Prelude

Release on: 2022-05-24

• Please refer to the 7.36.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• Debian packages are now built on Debian 8. Newly built DEBs are supported on Debian >= 8 and Ubuntu >= 14.
• The OTLP endpoint will no longer enable the legacy OTLP/HTTP endpoint 0.0.0.0:55681 by default. To keep using the legacy endpoint, explicitly declare it via the otlp_config.receiver.protocols.http.endpoint configuration setting or its associated environment variable,DD_OTLP_CONFIG_RECEIVER_PROTOCOLS_HTTP_ENDPOINT.
• Package signing keys were rotated:
  • DEB packages are now signed with key AD9589B7, a signing subkey of key F14F620E
  • RPM packages are now signed with key FD4BF915

New Features

• Adding support for IBM cloud. The agent will now detect that we're running on IBM cloud and collect host aliases (vm name and ID).
• Added event collection in the Helm check. The feature is disabled by default. To enable it, set the collect_events option to true.
• Adds a service check for the Helm check. The check fails for a release when its latest revision is in "failed" state.
• Adds a kube_qos (quality of service) tag to metrics associated with kubernetes pods and their containers.
• CWS can now track network devices creation and load TC classifiers dynamically.
• CWS can now track network namespaces.
• The DNS event type was added to CWS.
• The OTLP ingest endpoint is now considered GA for metrics.

Enhancement Notes

• Traps OIDs are now resolved to names using user-provided 'traps db' files in snmp.d/traps_db/.
• The Agent now supports a single ad.datadoghq.com/$IDENTIFIER.checks annotation in Kubernetes Pods and Services to configure Autodiscovery checks. It merges the contents of the existing "check_names", init_configs (now optional), and instances annotations into a single JSON value.
• DD_URL environment variable can now be used to set the Datadog intake URL just like DD_DD_URL. If both DD_DD_URL and DD_URL are set, DD_DD_URL will be used to avoid breaking change.
• Added a process-agent version command, and made the output mimic the core agent.
• Windows: Add Datadog registry to Flare.
• Add --service flag to stream-logs command to filter streamed logs in detail.
• Support a simple date pattern for automatic multiline detection
• APM: The OTLP ingest stringification of non-standard Datadog values such as Arrays and KeyValues is now consistent with OpenTelemetry attribute stringification.
• APM: Connections to upload profiles to the Datadog intake are now closed after 47 seconds of idleness. Common tracer setups send one profile every 60 seconds, which coincides with the intake's connection timeout and would occasionally lead to errors.
• The Cluster Agent now exposes a new metric cluster_checks_configs_info. It exposes the node and the check ID as tags.
• KSM core check: add a new kubernetes_state.cronjob.complete service check that returns the status of the most recent job for a cronjob.
• Retry more HTTP status codes for the logs agent HTTP destination.
• COPYRIGHT-3rdparty.csv now contains each copyright statement exactly as it is shown on the original component.
• Adds sidecar_present and sidecar_count tags on Cloud Foundry containers that run apps with sidecar processes.
• Agent flare now includes output from the process and container checks.
• Add the --cfgpath parameter in the Process Agent replacing --config.
• Add the check subcommand in the Process Agent replacing --check (-check). Only warn once if the -version flag is used.
• Adds human readable output of process and container data in the check command for the Process Agent.
• The Agent flare command now collects Process Agent performance profile data in the flare bundle when the --profile flag is used.

Deprecation Notes

• Deprecated process-agent --vesion in favor of process-agent version.
• The logs configuration use_http and use_tcp flags have been deprecated in favor of force_use_http and force_use_tcp.
• OTLP ingest: metrics.send_monotonic_counter has been deprecated in favor of metrics.sums.cumulative_monotonic_mode. metrics.send_monotonic_counter will be removed in v7.37.
• OTLP ingest: metrics.report_quantiles has been deprecated in favor of metrics.summaries.mode. metrics.report_quantiles will be removed in v7.37 / v6.37.
• Remove the unused --ddconfig (-ddconfig) parameter. Deprecate the --config (-config) parameter (show warning on usage).
• Deprecate the --check (-check) parameter (show warning on usage).

Bug Fixes

• Bump GoSNMP to fix incomplete support of SNMP v3 INFORMs.
• APM: OTLP: Fixes an issue where attributes from different spans were merged leading to spans containing incorrect attributes.
• APM: OTLP: Fixed an inconsistency where the error message was left empty in cases where the "exception" event was not found. Now, the span status message is used as a fallback.
• Fixes an issue where some data coming from the Agent when running in ECS Fargate did not have task_*, ecs_cluster_name, region, and availability_zone tags.
• Collect the "0" value for resourceRequirements if it has been set
• Fix a bug introduced in 7.33 that could prevent auto-discovery variable %%port_<name>%% to not be resolved properly.
• Fix a panic in the Docker check when a failure happens early (when listing containers)
• Fix missing docker.memory.limit (and docker.memory.in_use) on Windows
• Fixes a conflict preventing NPM/USM and the TCP Queue Length check from being enabled at the same time.
• Fix permission of "/readsecret.sh" script in the agent Dockerfile when executing with dd-agent user (for cluster check runners)
• For Windows, fixes problem in upgrade wherein NPM driver is not automatically started by system probe.
• Fix Gohai not being able to fetch network information when running on a non-English windows (when the output of commands like ipconfig were not in English). gohai no longer relies on system commands but uses Golang net package instead (same as Linux hosts). This bug had the side effect of preventing network monitoring data to be linked back to the host.
• Time-based metrics (for example, kubernetes_state.pod.age, kubernetes_state.pod.uptime) are now comparable in the Kubernetes state core check.
• Fix a risk of panic when multiple KSM Core check instances run concurrently.
• For Windows, includes NPM driver 1.3.2, which has a fix for a BSOD on system probe shutdown.
• Adds new --json flag to check. process-agent check --json now outputs valid json.
• On Windows, includes NPM driver update which fixes performance problem when host is under high connection load.
• Previously, the Agent could not log the start or end of a check properly after the first five check runs. The Agent now can log the start and end of a check correctly.

Other Notes

• Include pre-generated trap db file in the conf.d/snmp.d/traps_db/ folder.
• Gohai dependency has been upgraded. This brings a newer version of gopsutil and a fix when fetching network information in non-english Windows (see fixes section).
