I have several Python scripts that output metrics to rrd formatted files. Although I have been using rrdtool for graphing, I am wondering if there is any simple way that I can directly graph rrd files in Grafana.
I have found a few possibilities but they seem to require the rrd files to have been generated through Cacti or OpenNMS.
The Grafana RRD Server perhaps? https://github.com/doublemarket/grafana-rrd-server
