Telegraf 1.36 introduces a new feature allowing users to add labels to plugins and dynamically control their activation using selectors, offering greater configurational flexibility, particularly in environments with multiple Telegraf instances. Labels, which are key-value pairs, can be attached to any plugin type and used in conjunction with selectors to dictate which plugins run under specific conditions, such as distinct environments like staging or production. This feature enables fine-grained control over plugin execution without removing configuration blocks, facilitates environment-based filtering, supports multi-tenant setups, and aids in gradual rollouts or feature gating by allowing users to define plugins with varying levels of metric detail. With these capabilities, users can optimize resource usage, streamline operations, and enhance deployment strategies by filtering plugin instances at startup, all of which are supported by the use of predicate expressions in selectors to evaluate and manage plugin labels effectively.
