1.2.0 (2025-06-05)

Release 1.2.0 introduces Federated Mode support, comprehensive Helm Schema Validation, enhanced Configuration Management, and numerous improvements to observability, reliability, and maintainability. This release significantly expands deployment flexibility while strengthening data quality and operational efficiency.

Key Features

  • Federated Mode Support: The CloudZero agent now supports federated mode deployment to help support large clusters. In this mode, the Agent runs on each node in the cluster instead of a single Agent for all nodes. To enable, set defaults.federation.enabled to true.
  • Comprehensive Helm Schema Validation: We have extended the JSON Schema validation to cover the entire configuration, providing much earlier feedback of any issues.
  • New "helmless" tool: We have added a new "cloudzero-helmless" tool, which can be used to show the minimal difference between the default configuration and the configuration as used in the chart installation. This effectively recreates a minimized overrides overrides file.

Additional Enhancements

  • Improved Load Balancing: Enhanced HTTP connection handling with periodic connection rotation to ensure proper load distribution across service replicas in multi-replica deployments.
  • Observability and Debugging: Enhanced logging with configurable Prometheus log levels, and reduced log noise by moving health checks to trace level.
  • Security and Reliability: Added default Pod Disruption Budgets for improved availability.
  • Configuration ConfigMap: We now create a ConfigMap with the entire Helm chart configuration, to make debugging much easier.
  • Reduced storage usage: By default, we now store metric files on the aggregator for 7 days instead of 90, significantly reducing storage requirements.

Notable Bug Fixes

  • Eliminate unnecessary replays: Fixed an issue in the shipper which could cause the shipper to replay files repeatedly, instead of once, after receiving a request to replay a file.
  • Allow out-of-order metrics: In some (relatively rare) cases, we were seeing metrics being dropped as they were arriving out of order. There is now a configuration option for setting a window where they will still be accepted, which defaults to 5 minutes.

Upgrade Steps

To upgrade to version 1.2.0, run the following command:

helm upgrade --install <RELEASE_NAME> cloudzero/cloudzero-agent -n <NAMESPACE> --create-namespace -f configuration.example.yaml --version 1.2.0
