| description.long | Fluentd is an open source data collector that consolidates logs and events from multiple applications and systems into a unified pipeline, enabling better data routing, processing, and consumption across your infrastructure. | A cost-effective, full-stack observability solution that ingests and monitors logs, traces, metrics, and real-user monitoring data with native OpenTelemetry support. Available as a managed cloud service or self-hosted open-source deployment, using compression and columnar storage to dramatically reduce infrastructure costs. |
