Metricbeat has introduced a new concept called "light modules," which are predefined configurations for generic metricsets that do not require Go code and are designed to facilitate the monitoring of services using existing protocols supported by Metricbeat. These light modules allow users to extend Metricbeat functionality by providing a way to share configurations and dashboards, making it easier and faster to develop new modules for services that can be monitored using existing metricsets. A notable example is the light module for CockroachDB, which uses the Prometheus collector metricset but customizes the metrics endpoint. Light modules are structured with metadata files such as module.yml and manifest.yml, and they can include documentation, field mappings, and dashboards. They serve as a fallback mechanism, where Metricbeat will load a light module if a native module is not found in the configuration. This approach is already being applied to services like AWS ELB and is expected to expand to more services, with ongoing work to improve tooling and support for contributors in developing these modules.
