Grafana dashboard: NiFi Monitoring
Description: General view of Nifi 


# NiFi Exporter

Prometheus exporter for Nifi metrics written in python  
Data is scraped by [prometheus](https://prometheus.io).  
Based on the nifi exporter  
https://github.com/mormor83/NiFi_Exporter  
  
## Metrics

All metrics are prefixed with "nifi_".
