Even in a cloud-native world, plain old log files remain one of the richest sources of diagnostic truth in any system. The OpenTelemetry Filelog Receiver is how you bring them into a modern observability pipeline. But getting it right in production takes more than pointing it at a directory. In this guide, we cover everything you need to build a reliable, production-ready log ingestion pipeline with the filelog receiver: 1. The discover, read, parse, and emit loop that underpins everything 2. Parsing unstructured logs with regex operators and named capture groups 3. Handling multiline logs and stack traces without splitting them into fragments 4. Checkpointing with a storage extension to survive restarts without losing or duplicating data 5. Handling log rotation, compressed files, and sequential file ordering 6. Performance tuning for high-volume environments with hundreds of log files If your systems still write to disk and you want those logs as first-class OpenTelemetry data, this one's for you.
