> I am wondering if Teiid Wildfly in the meantime provides a metrics interface to be scraped with Prometheus or if there might be a plugin available which implements such an interface.
There should be examples out there of WildFly and Prometheus agent. Once you have the Prometheus agent installed you need a config, like jmx_exporter/wildfly-10.yaml at master · prometheus/jmx_exporter · GitHub
All of the Teiid admin DMR stuff that is available over the cli is exposed in JMX, so you just need to add whatever you want to the agent config and you'll have your metrics exported.
thanks for the links. Sounds good.
