We use Grafana to visualize IT infrastructure monitoring data. We have real-time, historical, and trend data that we can visualize in a flexible manner using Grafana. We use Zabbix to collect, process, and store the data. Zabbix has its own inbuilt visualization widgets, dashboards, and graphs, however, Grafana adds more flexibility. We have integrated Zabbix with Grafana using the Zabbix API which gives access to almost all components of the Zabbix Software.
Our environment is on-premises so we have both Zabbix and Grafana locally installed.
