Agent

Prelude

Release on: 2024-02-19

Please refer to the 7.51.0 tag on integrations-core for the list of changes on the Core Checks

The orchestrator check is moving from the Process Agent to the Core Agent. Any orchestrator configuration set on the Process Agent will need to be moved to the Core Agent. No other changes are required. If you need to go back to the old check, you can do so temporarily by manually setting the environment variable DD_ORCHESTRATOR_EXPLORER_RUN_ON_NODE_AGENT to false. The Process Agent pod check will be deprecated in the following release.
Upgrade the Python version from 3.9 to 3.11.

Add support for ARM64 SLES flavor of datadog-agent
Add support for multiple users when listening for SNMP traps.
Add check_delay metric in Agent telemetry
Add an ETW component for ETW tracing.
Add an ETW APM tracer component to forward .Net ETW events to the Tracer Agent.
DBM: Add configuration options to SQL obfuscator to customize the
normalization of SQL statements:
- KeepTrailingSemicolon - disable removing trailing semicolon. This option is only valid when ObfuscationMode is obfuscate_and_normalize.
- KeepIdentifierQuotation - disable removing quotation marks around identifiers. This option is only valid when ObfuscationMode is obfuscate_and_normalize.
CWS: [BETA] early support based on ptrace for platforms with no eBPF support. Only processes and files are currently supported.
Add msodbcsql18 linux dependency needed for SQL Server to run in Docker Agent.
Add timestamps to the logs HTTP client
Add support for Oracle Active Data Guard.
Re-enable Aerospike in SUSE packages.
The Windows Registry integration can now send the registry values as logs.

Updated the ntp check to support the default location of chrony.conf on Ubuntu (/etc/chrony/chrony.conf).
Agents are now built with Go 1.21.5.
CWS: Reloading the datadog-agent-sysprobe systemd service now reloads the runtime security policies.
CWS: Added ssdeep file hashing algorithm support.
USM will report the actual status code of the HTTP traffic, instead of reporting only the status code family (2xx, 3xx, etc.).
Improved performance of the activity sampling query on RDS and Oracle Cloud databases.
OTLP ingest log timestamps (i.e. '@timestamp') now include milliseconds.
Always report the following telemetry metrics about the retry queue capacity:
- datadog.agent.retry_queue_duration.capacity_secs
- datadog.agent.retry_queue_duration.bytes_per_sec
- datadog.agent.retry_queue_duration.capacity_bytes
Support container metrics for kata containers using containerd.
System Probe can now expose its healthcheck on a dedicated HTTP port. The Kubernetes daemonset uses this by default on port 5558.

The config value ipc_address is deprecated in favor of cmd_host.
service_monitoring_config.process_service_inference.enabled is deprecated and replaced by system_probe_config.process_service_inference.enabled service_monitoring_config.process_service_inference.use_windows_service_name is deprecated and replaced by system_probe_config.process_service_inference.use_windows_service_name
Removes freetds and msodbcsql18 dependencies for py2.
Removes postgresql dependency after upgrading psycopg2 to v2.9 in integrations-core. psycopg2 now comes with pre-built wheel for arm architecture.
An error will now be logged if replace tags are used to change the Agent "env", since this could have negative side effects. At this time, an error is logged, but future versions may explicitly disallow this to avoid bugs. See https://docs.datadoghq.com/getting_started/tracing/#environment-name for instructions on setting the env, and #21253 for more details about this issue.

CWS/CSPM: Fixes the hostname value attached to CWS and CSPM events, which in rare cases the security agent computed incorrectly.
Fix file_handle core check on Darwin by using sysctl system call.
Fix spikes for bandwidth usage metric when interface speed is auto-adjusted.
Fixes Agent startup script when enabling OOM Kill and TCP Queue Length checks to prevent crashes when restarting the container.
Fix a spewing error message ("DCA Client not initialized by main provider, cannot post heartbeat") in the cluster check runner log during CLC initialization.
Fixed Logs Agent additional endpoints to respect their logs_no_ssl setting.
[DBM] Add Oracle broken connection handling on Windows
Fix indentation in conf.yaml.example.
Bug fix for empty database names in query samples.
Bug fix for the Korean character set for Windows.
Fixing the issue with a Korean character set for Windows.

Enable Horizontal Pod Autoscaler collection for the Orchestrator by default
Add isolate command to clusterchecks to make it easier to pinpoint a check that that is causing high CPU/memory usage. Command can be run in the cluster agent with: datadog-cluster-agent clusterchecks isolate --checkID=<checkID>

Fixes a bug that would trigger unnecessary APIServer List requests from the Cluster Agent or Cluster Checks Runner.
