Description

Recently something has been introduced into the build breaking the prometheus scraping for scm metrics from the /prom endpoint.  This at least affects 

TYPE scm_metrics_container_* metrics and

TYPE scm_node_manager_decommission* metrics.

 

To reproduce, start cluster configured with Prometheus.  With devel ozone cluster, 

 

export COMPOSE_FILE=docker-compose.yaml:monitoring.yaml
docker-compose up -d -scale datanode=3

 

in Browser goto url localhost:9090.  Try to display scm_node_manager* metrics, scm_metrics_container_* metrics.
