OpenTelemetry Collector supports logs, metrics, and traces via OTLP and includes exporters to S3 and other object stores. Fluent Bit and Fluentd are lightweight alternatives for host and container log forwarding. For high-throughput streaming, Apache Kafka with an S3 sink connector or AWS Kinesis Data Firehose are common choices. Cribl Stream adds security-focused routing, filtering, and enrichment on top of these pipelines.
