node_exporter_metrics is a Fluent Bit input plugin that polls Linux host operating-system and hardware metrics for Prometheus-compatible export. Set scrape_interval in seconds, then route the records to prometheus_exporter, which exposes them at an HTTP /metrics endpoint. section 5.6.1
Configure the collection and export path with these choices:
- Set tag and tag properties for the collected node records. section 5.6.1
- Set the exporter host and port; use add_label with space-separated name and value pairs for Prometheus labels. section 5.6.1
- Use the Linux-only plugin for Linux environments; windows_exporter_metrics is the comparable Windows option. section 5.6.1
Expose node metrics
Configure node_exporter_metrics with tag node_metrics and scrape_interval 5, then expose matching records through prometheus_exporter on 0.0.0.0:9885. Start it with fluent-bit -c fluentbit/prometheus-exporter-output.conf and query <host>:9885/metrics. Output includes Prometheus HELP and TYPE lines plus metrics such as node_cpu_seconds_total and node_disk_reads_completed_total.
