Agent

Prelude

Release on: 2023-01-23

• Please refer to the 7.42.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• Downloading and installing official checks with agent integration install is no longer supported for Agent installations that do not include an embedded python3.

New Features

• Adding the kube_api_version tag to all orchestrator resources.

• Kubernetes Pod events generated by the kubernetes_apiserver can now benefit from the new cluster-tagger component in the Cluster-Agent.

• APM OTLP: Added compatibility for the OpenTelemetry Collector's datadogprocessor to the OTLP Ingest.

• The CWS agent now supports rules on mount events.

• Adding a configuration option, exclude_ec2_tags, to exclude EC2 instance tags from being converted into host tags.

• Adds detection for a process being executed directly from memory without the binary present on disk.

• Introducing agent sampling rates remote configuration.

• Adds support for secret_backend_command_sha256 SHA for the secret_backend_command executable. If secret_backend_command_sha256 is used, the following restrictions are in place:

  • Value specified in the secret_backend_command setting must be an absolute path.

  - Permissions for the datadog.yaml config file must disallow write access by users other than ddagentuser or Administrators on Windows or the user running the Agent on Linux and macOS. The agent will refuse to start if the actual SHA256 of the secret_backend_command executable is different from the one specified by secret_backend_command_sha256. The secret_backend_command file is locked during verification of SHA256 and subsequent run of the secret backend executable.

• Collect network devices topology metadata.

• Add support for AWS Lambda Telemetry API

• Adds three new metrics collected by the Lambda Extension

  `aws.lambda.enhanced.response_latency`: Measures the elapsed time in milliseconds from when the invocation request is received to when the first byte of response is sent to the client.

  `aws.lambda.enhanced.response_duration`: Measures the elapsed time in milliseconds between sending the first byte of the response to the client and sending the last byte of the response to the client.

  `aws.lambda.enhancdd.produced_bytes`: Measures the number of bytes returned by a function.

• Create cold start span representing time and duration of initialization of an AWS Lambda function.

Enhancement Notes

• Adds both the StartTime and ScheduledTime properties in the collector for Kubernetes pods.
• Add an option (hostname_trust_uts_namespace) to force the Agent to trust the hostname value retrieved from non-root UTS namespaces (Linux only).
• Metrics from Giant Swarm pause containers are now excluded by default.
• Events emitted by the Helm check now have "Error" status when the release fails.
• Add an annotations_as_tags parameter to the kubernetes_state_core check to allow attaching Kubernetes annotations as Datadog tags in a similar way that the labels_as_tags parameter does.
• Adds the windows_counter_init_failure_limit option. This option limits the number of times a check will attempt to initialize a performance counter before ceasing attempts to initialize the counter.
• [netflow] Expose collector metrics (from goflow) as Datadog metrics
• [netflow] Add prometheus listener to expose goflow telemetry
• OTLP ingest now uses the minimum and maximum fields from delta OTLP Histograms and OTLP ExponentialHistograms when available.
• The OTLP ingest endpoint now reports the first cumulative monotonic sum value if the timeseries started after the Datadog Agent process started.
• Added the workload-list command to the process agent. It lists the entities stored in workloadmeta.
• Allows running secrets in the Process Agent on Windows by sandboxing secret_backend_command execution to the ddagentuser account used by the Core Agent service.
• Add process_context tag extraction based on a process's command line arguments for service monitoring. This feature is configured in the system-probe.yaml with the following configuration: service_monitoring_config.process_service_inference.enabled.
• Reduce the overhead of using Windows Performance Counters / PDH in checks.
• The OTLP ingest endpoint now supports the same settings and protocol as the OpenTelemetry Collector OTLP receiver v0.64.1
• The OTLP ingest endpoint now supports the same settings and protocols as the OpenTelemetry Collector OTLP receiver v0.66.0.

Deprecation Notes

• Removes the install-service Windows agent command.
• Removes the remove-service Windows agent command.

Security Notes

• Upgrade the wheel package to 0.37.1 for Python 2.
• Upgrade the wheel package to 0.38.4 for Python 3.

Bug Fixes

• APM: Fix an issue where container tags weren't working because of overwriting an essential tag on spans.
• APM OTLP: Fix an issue where a span's local "peer.service" attribute would not override a resource attribute-level service.
• On Windows, fixes a bug in the NPM network driver which could cause a system crash (BSOD).
• Create only endpoints check from prometheus scrape configuration when prometheus_scrape.service.endpoint option is enabled.
• Fix how Kubernetes events forwarding detects the Node/Host.
  • Previously Nodes' events were not always attached to the correct host.
  • Pods' events from "custom" controllers might still be not attached to a host if the controller doesn't set the host in the source.host event's field.
• APM: Fix SQL parsing of negative numbers and improve error message.
• Fix a potential panic when df outputs warnings or errors among its standard output.
• Fix a bug where a misconfig error does not show when hidepid=invisible
• The agent no longer wrongly resolves its hostname on ECS Fargate when requests to the Fargate API timeout.
• Metrics reported through OTLP ingest now have the interval property unset.
• Fix a PDH query handle leak that occurred when a counter failed to add to a query.
• Remove unused environment variables DD_AGENT_PY and DD_AGENT_PY_ENV from known environment variables in flare command.
• APM: Fix SQL obfuscator parsing of identifiers containing dollar signs.

Other Notes

Datadog Cluster Agent

New Features

• Supports the collection of custom resource definition and custom resource manifests for the orchestrator explorer.

Enhancement Notes

• Collects Unified Service Tags for the orchestrator explorer product.

7.41.1

Prelude

Release on: 2022-12-21

Enhancement Notes

• Agents are now built with Go 1.18.9.

7.41.0

Agent

Prelude

Release on: 2022-12-12

• Please refer to the 7.41.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• Troubleshooting commands in the Agent CLI have been moved to the diagnose command. troubleshooting metadata_v5 command is now diagnose show-metadata v5 and troubleshooting metadata_inventory is diagnose show-metadata inventory.
• Journald launcher can now create multiple tailers on the same journal when config_id is specified. This change enables multiple configs to operate on the same journal which is useful for tagging different units. Note: This may have an impact on CPU usage.
• Upgrade tracer_agent debugger proxy to use logs intake API v2 for uploading snapshots
• The Agent now defaults to TLS 1.2 instead of TLS 1.0. The force_tls_12 configuration parameter has been removed since it's now the default behavior. To continue using TLS 1.0 or 1.1, you must set the min_tls_version configuration parameter to either tlsv1.0 or tlsv1.1.

New Features

• Added a required infrastructure to enable protocol classification for Network Performance Monitoring in the future. The protocol classification will allow us to label each connection with a L7 protocol. The features requires Linux kernel version 4.5 or greater.
• parse the snmp configuration from the agent and pass it to the integrated snmpwalk command in case the customer only provides an ip address
• The Agent can send its own configuration to Datadog to be displayed in the Agent Configuration section of the host detail panel. See https://docs.datadoghq.com/infrastructure/list/#agent-configuration for more information. The Agent configuration is scrubbed of any sensitive information and only contains configuration you’ve set using the configuration file or environment variables.
• Windows: Adds support for Windows Docker "Process Isolation" containers running on a Windows host.

Enhancement Notes

• APM: All spans can be sent through the error and rare samplers via custom feature flag error_rare_sample_tracer_drop. This can be useful if you want to run those samplers against traces that were not sampled by custom tracer sample rules. Note that even user manual drop spans may be kept if this feature flag is set.
• APM: The trace-agent will log failures to lookup CPU usage at error level instead of debug.
• Optionally poll Agent and Cluster Agent integration configuration files for changes after startup. This allows the Agent/Cluster Agent to pick up new integration configuration without a restart. This is enabled/disabled with the autoconf_config_files_poll boolean configuration variable. The polling interval is configured with the autoconf_config_files_poll_interval (default 60s). Note: Dynamic removal of logs configuration is currently not supported.
• Added telemetry for the "container-lifecycle" check.
• On Kubernetes, the "cluster name" can now be discovered by using the Node label ad.datadoghq.com/cluster-name or any other label key configured using to the configuration option: kubernetes_node_label_as_cluster_name
• Agents are now built with Go 1.18.8.
• Go PDH checks now all use the PdhAddEnglishCounter API to ensure proper localization support.
• Use the windows_counter_refresh_interval configuration option to limit how frequently the PDH object cache can be refreshed during counter initialization in golang. This replaces the previously hardcoded limit of 60 seconds.
• [netflow] Add disable port rollup config.
• The OTLP ingest endpoint now supports the same settings and protocol as the OpenTelemetry Collector OTLP receiver v0.61.0.
• The disable_file_logging setting is now respected in the process-agent.
• The process-agent check [check-name] command no longer outputs to the configured log file to reduce noise in the log file.
• Logs a warning when the process agent cannot read other processes due to misconfiguration.
• DogStatsD caches metric metadata for shorter periods of time, reducing memory usage when tags or metrics received are different across subsequent aggregation intervals.
• The agent CLI subcommands related to Windows services are now consistent in use of dashes in the command names (install-service, start-service, and so on). The names without dashes are supported as aliases.
• The Agent now uses the V2 API to submit series data to the Datadog intake by default. This can be reverted by setting use_v2_api.series to false.

Deprecation Notes

• APM: The Rare Sampler is now disabled by default. If you wish to enable it explicitly you can set apm_config.enable_rare_sampler or DD_APM_ENABLE_RARE_SAMPLER to true.

Bug Fixes

• APM: Don't include extra empty 'env' entries in sampling priority output shown by agent status command.

• APM: Fix panic when DD_PROMETHEUS_SCRAPE_CHECKS is set.

• APM: DogStatsD data can now be proxied through the "/dogstatsd/v1/proxy" endpoint and the new "/dogstatsd/v2/proxy" endpoint over UDS, with multiple payloads separated by newlines in a single request body. See https://docs.datadoghq.com/developers/dogstatsd#setup for configuration details.

• APM - remove extra error message from logs.

• Fixes an issue where cluster check metrics would be sometimes sent with the host tags.

• The containerd check no longer emits events related with pause containers when exclude_pause_container is set to true.

• Discard aberrant values (close to 18 EiB) in the container.memory.rss metric.

• Fix Cloud Foundry CAPI Metadata tags injection into application containers.

• Fix Trace Agent's CPU stats by reading correct PID in procfs

• Fix a potential panic when df outputs warnings or errors among its standard output.

• The OTLP ingest is now consistent with the Datadog exporter (v0.56+) when getting a hostname from OTLP resource attributes for metrics and traces.

• Make Agent write logs when SNMP trap listener starts and Agent receives invalid packets.

• Fixed a bug in the workloadmeta store. Subscribers that asked to receive only unset events mistakenly got set events on the first subscription for all the entities present in the store. This only affects the container_lifecycle check.

• Fix missing tags on the kubernetes_state.cronjob.complete service check.

• In kubernetes_state_core check, fix the labels_as_tags feature when the same Kubernetes label must be turned into different Datadog tags, depending on the resource:

  labels_as_tags:
  daemonset:
  first_owner: kube_daemonset_label_first_owner

  deployment:
  first_owner: kube_deployment_label_first_owner

• Normalize the EventID field in the output from the windowsevent log tailer. The type will now always be a string containing the event ID, the sometimes present qualifier value is retained in a new EventIDQualifier field.

• Fix an issue where the security agent would panic, sending on a close channel, if it received a signal when shutting down while all components were disabled.

• Fix tokenization of negative numeric values in the SQL obfuscator to remove extra characters prepended to the byte array.

Datadog Cluster Agent

New Features

• Add Namespace collection in the orchestrator check and enable it by default.

Enhancement Notes

• Improves performance of the Cluster Agent admission controller on large pods.

7.40.1

Release Notes

7.40.1

Prelude

Release on: 2022-11-09

• Please refer to the 7.40.1 tag on integrations-core for the list of changes on the Core Checks

Enhancement Notes

• Agents are now built with Go 1.18.8.

Bug Fixes

• Fix log collection on Kubernetes distributions using cri-o like OpenShift, which began failing in 7.40.0.

7.40.0

Agent

Prelude

Release on: 2022-11-02

• Please refer to the 7.40.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• Starting Agent 7.40, the Agent will fail to start when unable to determine hostname instead of silently using unrelevant hostname (usually, a container id). Hostname resolution is key to many features and failure to determine hostname means that the Agent is not configured properly. This change mostly affects Agents running in containerized environments as we cannot rely on OS hostname.

• Universal Service Monitoring now requires a Linux kernel version of 4.14 or greater.

New Features

• The Agent RPM package now supports Amazon Linux 2022 and Fedora 30+ without requiring the installation of the additional libxcrypt-compat system package.
• Add support for CAPI metadata and DCA tags collection in PCF containers.
• Add a username and password dialog window to the Windows Installer
• APM: DogStatsD data can now be proxied through the "/dogstatsd/v1/proxy" endpoint over UDP. See https://docs.datadoghq.com/developers/dogstatsd#setup for configuration details.
• Cloud Workload Security now has Agent version constraints for Macros in SECL expressions.
• Added the "helm_values_as_tags" configuration option in the Helm check. It allows users to collect helm values from a Helm release and use them as tags to attach to the metrics and events emitted by the Helm check.
• Enable the new DogStatsD no-aggregation pipeline, capable of processing metrics with timestamps. Set dogstatsd_no_aggregation_pipeline to false to disable it.
• Adds ability to identify the interpreter of a script inside a script via the shebang. Example rule would be exec.interpreter.file.name == ~"python*". This feature is currently limited to one layer of nested script. For example, a python script in a shell script will be caught, but a perl script inside a python script inside a shell script will not be caught.

Enhancement Notes

• JMXFetch now supports ZGC Cycles and ZGC Pauses beans support out of the box.

• Adds new aws.lambda.enhanced.post_runtime_duration metric for AWS Lambda functions. This gauge metric measures the elapsed milliseconds from when the function returns the response to when the extensions finishes. This includes performing activities like sending telemetry data to a preferred destination after the function's response is returned. Note that aws.lambda.enhanced.duration is equivalent to the sum of aws.lambda.enhanced.runtime_duration and aws.lambda.enhanced.post_runtime_duration.

• Add the flare command to the Cloud Foundry cluster agent to improve support experience.

• Add CreateContainerError and InvalidImageName to waiting reasons for kubernetes_state.container.status_report.count.waiting in the Kubernetes State Core check.

• [netflow] Ephemeral Port Rollup

• APM: A warning is now logged when the agent is under heavy load.

• APM: The "http.status_code" tag is now supported as a numeric value too when computing APM trace stats. If set as both a string and a numeric value, the numeric value takes precedence and the string value is ignored.

• APM: Add support for cgroup2 via UDS.

• A new config option, logs_config.file_wildcard_selection_mode, allows you to configure how log wildcard file matches are prioritized if the number of matches exceeds logs_config.open_files_limit.

  The option defaults to by_name which is the previous behavior. The new option is by_modification_time which prioritizes more recently modified files, but using it can result in slower performance compared to using by_name.

• Agents are now built with Go 1.18.7. This version of Go brings changes to the garbage collection runtime that may change the Agent's memory usage. In internal testing, the RSS of Agent processes showed a minor increase of a few MiB, while CPU usage remained consistent. Reducing the value of GOGC as described in the Go documentation was effective in reducing the memory usage at a modest cost in CPU usage.

• KSM Core check: Add the helm_chart tag automatically from the standard helm label helm.sh/chart.

• Helm check: Add a helm_chart tag, equivalent to the standard helm label helm.sh/chart (see https://helm.sh/docs/chart_best_practices/labels/).

• The OTLP ingest endpoint now supports the same settings and protocol as the OpenTelemetry Collector OTLP receiver v0.60.0. In particular, this drops support for consuming OTLP/JSON v0.15.0 or below payloads.

• Improve CCCache performance on cache miss, significantly reducing the number of API calls to the CAPI.

• Add more flags to increase control over the CCCache, such as refresh_on_cache_miss, sidecars_tags, and isolation_segments_tags flags under cluster_agent properties.

• Windows: Add a config option to control how often the agent refreshes performance counters.

• Introduces an unbundle_events config to the docker integration. When set to true, Docker events are no longer bundled together by image name, and instead generate separate Datadog events.

• Introduces an unbundle_events config to the kubernetes_apiserver integration. When set to true, Kubernetes events are no longer bundled together by InvolvedObject, and instead generate separate Datadog events.

• On Windows the Agent now uses high-resolution icon where possible. The smaller resolution icons have been resampled for better visibility.

Known Issues

• APM: OTLP Ingest: resource attributes such as service.name are correctly picked up by spans.
• APM: The "/dogstatsd/v1/proxy" endpoint can only accept a single payload at a time. This will be fixed in the v2 endpoint which will split payloads by newline.

Deprecation Notes

• The following Windows Agent container versions are removed: 1909, 2004, and 20H2.

Bug Fixes

• Add the device field to the MetricPayload to ensure the device tag is properly handled by the backend.
• APM: Revised support for tracer single span sampling. See datadog-agent/pull/13461.
• Fixed a problem that could trigger in the containerd collector when fetching containers from multiple namespaces.
• Fixed a crash when dogstatsd_metrics_stats_enable is true
• Fix a bug in Autodiscovery preventing the Agent to correctly schedule checks or logs configurations on newly created PODs during a StatefulSet rollout.
• The included aerospike Python package is now correctly built against the embedded OpenSSL and thus the Aerospike integration can be successfully used on RHEL/CentOS.
• Fix configresolver to continue parsing when a null value is found.
• Fixed issue with CPU count on MacOS
• The container CPU limit that is reported by docker and container checks on ECS was not defaulting to the task limit when no CPU limit is set at container level.
• Fix potential panic when removing a service that the log agent is currently tailing.
• On SUSE, fixes the permissions declared in the package list of the RPM package. This was causing package conflicts between the datadog-agent package and other packages with files in /usr/lib/systemd/system.
• Fixed a resource leak in the helm check.
• Fix golang performance counter initialization errors when counters are not available during agent/check init time. Checks now retry the counter initilization on each interval.
• [snmp] Cache snmp dynamic tags from devices

Other Notes

• JMXFetch upgraded to 0.47.1 https://github.com/DataDog/jmxfetch/releases/0.47.1
• The logs_config.cca_in_ad feature flag now defaults to true. This selects updated codepaths in Autodiscovery and the Logs Agent. No behavior change is expected. Please report any behavior that is "fixed" by setting this flag to false.

Datadog Cluster Agent

New Features

• Experimental: The Datadog Admission Controller can inject the Python APM library into Kubernetes containers for auto-instrumentation.
• The orchestrator check is now able to discover resources to collect based on API groups available in the Kubernetes cluster.

Enhancement Notes

• The admission controller now injects variables and volume mounts to init containers in addition to regular containers.
• Chunk orchestrator payloads by size and weight
• KSM Core check: Add the helm_chart tag automatically from the standard helm label helm.sh/chart.
• Helm check: Add a helm_chart tag, equivalent to the standard helm label helm.sh/chart (see https://helm.sh/docs/chart_best_practices/labels/).

Bug Fixes

• Fixed an edge case in the Admission Controller when mutateUnlabelled is enabled and configMode is set to socket. This combination could prevent the creation of new DaemonSet Agent pods.
• Fixed a resource leak in the helm check.

7.39.2

Prelude

Release on: 2022-10-12

Bug Fixes

• Cloud Workload Security uses a default Traffic Control filter priority of 10.
• Traffic Control filters priority and handle can be set from the configuration of Cloud Workload Security in system-probe.yaml.

7.39.1

Prelude

Release on: 2022-09-27

Security Notes

• Bump github.com/open-policy-agent/opa to v0.43.1 to patch CVE-2022-36085.

Other Notes

• Bump embedded Python3 to 3.8.14.
• Deactivated support of HTTP/2 in all non localhost endpoint used by Datadog Agent and Cluster Agent. (except endpoints)

7.39.0

Agent

Prelude

Release on: 2022-09-12

• Please refer to the 7.39.0 tag on integrations-core for the list of changes on the Core Checks

Upgrade Notes

• Starting with version 6.39.0, Agent 6 is no longer built for macOS. Only Agent 7 will be built for macOS going forward. macOS 10.14 and above are supported with Agent 7.39.0.

New Features

• Add an integrated snmpwalk command to perform a walk for all snmp versions based on the gosnmp library.
• APM: Add two options under the vector config prefix to send traces to Vector instead of Datadog. Set vector.traces.enabled to true. Set vector.traces.url to point to a Vector endpoint. This overrides the main endpoint. Additional endpoints remains fully functional.

Enhancement Notes

• Add the tagger-list command to the process-agent to ease tagging issue investigation.
• Update SNMP traps database with bit enumerations.
• Resolve SNMP trap variables with bit enumerations to their string representation.
• Logs: Support filtering on arbitrary journal log fields
• APM: The trace-agent version string has been made more consistent and is now available in different build environments.
• Delay starting the auto multi-line detection timeout until at least one log has been processed.
• The helm check has new configuration parameters:
  • extra_sync_timeout_seconds (default 120)
  • informers_resync_interval_minutes (default 10)
• Improves the labelsAsTags feature of the Kubernetes State Metrics core check by performing the transformations of characters ['/' , '-' , '.'] to underscores ['_'] within the Datadog agent. Previously users had to perform these conversions manually in order to discover the labels on their resources.
• The new min_tls_version configuration parameter allows configuration of the minimum TLS version used for connections to the Datadog intake. This replaces the force_tls_12 configuration parameter which only allowed the minimum to be set to tlsv1.2.
• The OTLP ingest endpoint now supports the same settings and protocol as the OpenTelemetry Collector OTLP receiver v0.56.0
• 'agent status' command output is now parseable as JSON directly from stdout. Before this change, the logger front-matter made it hard to parse 'status' output directly as JSON.
• Raise the default logs_config.open_files_limit to 200 on Windows and macOS. Raised to 500 for all other operating systems.
• Support disabling DatadogMetric autogeneration with the external_metrics_provider.enable_datadogmetric_autogen configuration option (enabled by default).

Deprecation Notes

• APM: The datadog.trace_agent.trace_writer.bytes_estimated metric has been removed. It was meant to be a metric used for debugging, without any user added value.
• APM: The trace-agent /info endpoint no longer reports "build_date".
• The force_tls_12 configuration parameter is deprecated, replaced by min_tls_version. If min_tls_version is not given, but force_tls_12 is true, then min_tls_version defaults to tlsv1.2.

Bug Fixes

• Traps variable OIDs that had the index as a suffix are now correctly resolved.
• Agent status command should always log at info level to allow full status output regardless of Agent log level settings.
• APM: The "datadog.trace_agent.otlp.spans" metric was incorrectly reporting span count. This release fixes that.
• Fix panic when Agent stops jmxfetch.
• Fixed a bug in Kubernetes Autodiscovery based on pod annotations: The Agent no longer skips valid configurations if other invalid configurations exist. Note: This regression was introduced in Agents 7.36.0 and 6.36.0
• Fix a bug in autodiscovery that would not unschedule some checks when check configuration contains secrets.
• Orchestrator check: make sure we don't return labels and annotations with a suffixed :
• Fixed a bug in the Docker check that affects the docker.containers.running metric. It was reporting wrong values in cases where multiple containers with different env, service, version, etc. tags were using the same image.
• Fixed a deadlock in the DogStatsD when running the capture (agent dogstatsd-capture). The Agent now flushes the captured messages properly when the capture stops.
• Fix parsing of init_config in AD annotations v2.
• The internal_profiling.period parameter is now taken into account by the agent.
• Fix duplicated check or logs configurations, targeting dead containers when containers are re-created by Docker Compose.
• Fix concurrent map access issues when using OTLP ingest.
• [orchestrator check] Fixes race condition during check startup.
• The Windows installer will now respect the DDAGENTUSER_PASSWORD option and update the services passwords when the user already exists.
• The KSM Core check now handles cron job schedules with time zones.
• The v5 metadata payload's filesystem information is now more robust against failures in the df command, such as when a mountpoint is stuck.
• Fixes a disk check issue in the Docker Agent where a disproportionate amount of automount request system logs would be produced by the host after each disk check run.
• [epforwarder] Update NetFlow EP forwarder default configs
• The Agent starts faster on a Windows Docker host with many containers running by fetching the containers in parallel.
• On Windows, NPM driver adds support for Receive Segment Coalescing. This works around a Windows bug which in some situations causes system probe to hang on startup

Cluster Agent

New Features

• Experimental: The Datadog Admission Controller can inject the Node and Java APM libraries into Kubernetes containers for auto-instrumentation.

Enhancement Notes

• When injecting env vars with the admission controller, env vars are now prepended instead of appended, meaning that Kubernetes [dependent environment variables](https://kubernetes.io/docs/tasks/inject-data-application/define-interdependent-environment-variables/) can now depend on these injected vars.
• The helm check has new configuration parameters:
  • extra_sync_timeout_seconds (default 120)
  • informers_resync_interval_minutes (default 10)
• Improves the labelsAsTags feature of the Kubernetes State Metrics core check by performing the transformations of characters ['/' , '-' , '.'] to underscores ['_'] within the Datadog agent. Previously users had to perform these conversions manually in order to discover the labels on their resources.

Bug Fixes

• Fix the DCA leader_election_is_leader metric that could sometimes report is_leader="false" on the leader instance
• Fixed an error when running datadog-cluster-agent status with DD_EXTERNAL_METRICS_PROVIDER_ENABLED=true and no app key set.
• The KSM Core check now handles cron job schedules with time zones.

Other Notes

• Align Cluster Agent version to Agent version. Cluster Agent will now be released with 7.x.y tags
