Agent Control release notesRSS

July 29
Agent Control v1.20.0

New features

  • Kubernetes: --release-name is now optional on uninstall-agent-control; omitting it skips deleting the release's own HelmRelease/HelmRepository CRs.
  • On-host: added nri-apache and nri-nginx agentTypes.
  • On-host: added nri-postgresql agentType.
  • On-host: added nri-mysql agentType.
  • On-host: added nri-memcached Agent Type.
  • Log files rotated have now 30 days of retention.
  • Added agent-type validate --file <path> subcommand to newrelic-agent-control-cli and newrelic-agent-control-k8s-cli for schema-level validation of agent type definition files.
  • Extended agent-type validate with semantic validation: every ${nr-var:X} reference in deployment must have a matching variables declaration.
  • Enable cache for remote Agent Type registry

Security updates

July 20
Agent Control v1.19.0

New features

  • On-host and Kubernetes: When an agent's type is bumped via a live remote config update, Agent Control now reconciles both per-agent and shared filesystems, deleting paths declared by the old type that no longer appear in any active agent's declarations. Co-owned shared paths still claimed by another active agent are preserved. On Kubernetes, k8s objects annotated with the old type are garbage-collected while new-type resources are left intact.
  • Adds oci-utils CLI to test/crates/oci-test-utils for pushing agent packages and agent type definitions to OCI registries from the command line (dev/test tooling; not published).
  • On-host agent-type parsing now validates reported_version_package: It must reference a declared package, and is required when more than one package is defined. Invalid configurations are rejected at parse time with a descriptive error. This reported_version_package determines which version is reported as agent.version.
  • Adds support for copy_from_file for on-host "in-agent" filesystem.
  • Adds support for shared_filesystem in on-host agent types. It includes a single-owner rule: Two agents claiming the same path in the shared-filesystem are invalid and reported as Failed.
  • On-host self-update: Skip sub-agent reconciliation when a self-update is in progress. When a single remote config both bumps the Agent Control version and changes a sub-agent's agent_type, the changed sub-agent is no longer recreated moments before the process restarts; the new config is stored and re-applied cleanly by the restarted process, avoiding a redundant sub-agent restart and telemetry gap.
  • On-host: Added support for nri-redis agentType for both Linux and Windows.
  • On-host health config: Replaced the flat health.http: / health.file: fields with an explicit checks: list. Each entry is discriminated by kind: (Process, Http, or File). The previously implicit supervised-process health check is now declared as kind: Process. An omitted or empty checks: list disables health reporting entirely.
  • On-host filesystem entries (file/dir) now always survive sub-agent stop, restart, and config-apply. A stray persistent: key in existing agent-type YAML is ignored rather than rejected.

Bug fixes

  • Added identifying attributes for each package specified in the agentType as package.version.<id>.
  • RPM packages now restore local_config.yaml from the .rpmsave backup left by a prior uninstall.

July 6
Agent Control v1.18.0

Features

  • Added exponential backoff and jitter retries to OCI artifact fetches using a new BackoffPolicy (configured under self_update.download_retry), replacing the previous with_retries(usize, Duration) API.
  • Added post-download script support for OCI packages.
  • Hardened service restart policies on Linux and Windows platforms (implementing systemd rate limiting: maximum of 5 restarts within 60 seconds) to prevent crash-looping from saturating CPU capacity.
  • Added support for retrieving remote agent type definitions directly from OCI registries.
  • Configured agent type definitions to tolerate unknown fields to ensure forward compatibility.
  • Added support for creating on-host agents without defining a health check, which disables health reporting for that agent.
  • Streamlined version tracking for on-host agents by deriving versions directly from OCI package metadata. This eliminates command-based version checking and removes the need for the deployment.version configuration in agent type definitions.
  • Replaced the filesystem configuration in on-host agent type definitions with an explicit, recursive, tagged-kind tree structure where every entry declares kind: file | dir | dir_content_from_map and dir entries nest using entries:.
  • Introduced a persistent flag (default value is set to false) for on-host filesystem entries; ephemeral entries are deleted when a sub-agent stops, while persistent entries remain until the agent is removed from the fleet.Reconciliation across writes is driven by a .ac-managed-paths.json manifest (reserved filename — agent types must not declare it) so paths Agent Control no longer owns are deleted while sub-agent-created files are preserved.
  • Introduced the shared-filesystem-dir variable for agent type configurations.
  • Extended the internal fs crate to support file copy operations.
  • Removed the filesystem manifest-based prune mechanism; Agent Control no longer deletes previously-declared paths dropped by subsequent configurations; agent-managed files are now reclaimed only when the agent is removed from the fleet.

Fixes

  • Fixed an on-host self-update issue where pushing an empty version: "" string from Fleet Control incorrectly triggered an image pull of the :latest OCI tag. It now correctly treats an empty string as a no-op (), matching the behavior of an absent version field.
