as DHIS 2 data volumes and user traffic grow, there is a need for sysadmins to perform monitoring of servers running DHIS 2 in a systematic way. By regularly monitoring your server(s), you can detect performance bottlenecks and fix problems early.
To help that effort, the developer team made several types of monitoring metrics available in version 2.33. The recommended approach for collecting, displaying and visualizing those metrics are through the Prometheus monitoring system and Grafana visualization tool. These tools are both open source and free of charge.
