Description:The nf-prometheus plugin exports Nextflow pipeline metrics to Prometheus and Grafana, specifically designed for on-premise HPC clusters (Slurm, shared filesystems, air-gapped environments) where head jobs run behind firewalls. It provides three export modes—textfile-first (no network needed), Pushgateway, and HTTP—enabling HPC operators to monitor Nextflow pipelines with their existing Prometheus stacks without adding dependencies or risk to pipeline execution.
