Dynatrace has introduced significant enhancements to its OneAgent command-line interface (CLI), allowing for more streamlined and efficient host management and configuration. With the release of OneAgent 1.189, users can now easily reconfigure hosts or host groups post-installation, set and manage tags and properties using the oneagentctl CLI tool, and toggle between different monitoring modes. These improvements eliminate the need for error-prone manual editing of configuration files by providing commands such as --set-host-tag, --set-host-property, and --restart-service, which enable users to perform operations quickly and effectively. The tool now supports adding custom host names and offers a faster method for configuration via CLI during installation, making it a powerful solution for managing large environments. Although the current focus is on enhancing the REST API for bulk reconfiguration, Dynatrace is open to user feedback for further improvements.
