Hey guys, In NiFi 1.x I have used the PrometheusReportingTask and the Metrics reporting strategy was set to "Root Process Group”.
On 2.x I can fetch the data from the REST API endpoint /nifi-api/flow/metrics/prometheus, but I can’t figure out how to restrict it to only the Root Process Group like before. Without any restrictions I get the metrics for every single component, which is too much to handle (50-60k metrics). Has anyone an idea on how I can replicate the old behavior? Kind regards, Christian Wahl
