Alexander Bij updated NIFI-16298:
---------------------------------
Description:
Improvement to be able to build a Grafana dashboard showing the Primary Node
and Cluster Coordinator based on the prometheus scrape.
The Prometheus flow metrics endpoint
({{{}/nifi-api/flow/metrics/prometheus{}}}) exposes cluster
membership/connectivity metrics, but nothing indicates which node currently
holds the Primary Node or Cluster Coordinator role. Building a "nodes in this
cluster" dashboard/table (one row per node, with its key stats) currently has
no way to mark which row is the Primary Node or the Cluster Coordinator without
querying NiFi's REST API separately and joining the data out-of-band.
Suggestion to add:
* {{cluster_is_primary_node [0,1]}}
* {{cluster_is_cluster_coordinator }}{{{}[0,1]{}}}{{{}{}}}
