           Starting 3.19, new installations of GHES will have OpenTelemetry metrics enabled and Collectd metrics disabled by default. You have the option to toggle between the two. Upgraded instances will retain their current settings. In about two to three releases, OpenTelemetry metrics will become the only supported metrics. To learn about OTel metrics, see [AUTOTITLE](/admin/monitoring-and-managing-your-instance/monitoring-your-instance/opentelemetry-metrics).
