The article discusses using logs for metering infrastructure component usage when integrating collectors or making HTTP requests is challenging. It presents Vector, an open-source project that can collect logs from applications and transform them into billable events for usage metering. The process involves configuring sources, transforms, and sinks in the Vector pipeline to consume logs, parse them, filter unnecessary data, and finally convert them into CloudEvents format supported by OpenMeter's ingest API. This approach is particularly useful for measuring low-level infrastructure components, legacy systems, or serverless applications without integrating collectors or triggering HTTP requests for every transaction.
