Interesting! Finally a Grafana user... Thanks Daniel, I will follow your links. That looks promising.
Is anyone using Grafana over Graphite?

Hi Robert, We use the following stack: - Prometheus to scrape metrics (https://prometheus.io/) - Prometheus node exporter to export "machine metrics" (Disk, network usage, etc.) (https://github.com/prometheus/node_exporter) - Prometheus JMX exporter to export "Solr metrics" (Cache usage, QPS, Response times...) (https://github.com/prometheus/jmx_exporter) - Grafana to visualize all the data scrapped by Prometheus ( https://grafana.com/) Best regards Daniel Ortega 2017-11-06 20:13 GMT+01:00 Petersen, Robert (Contr) < robert.peters...@ftr.com>: > PS I knew sematext would be required to chime in here! đ > > > Is there a non-expiring dev version I could experiment with?
