metrics system cann't startup

[dachn]

I start kyuubi server and metric system turn on in kyuubi-default.conf

kyuubi.metrics.enabled true 
kyuubi.metrics.prometheus.port 10019

and I got some info log like metic system is initialized and start like this:

18:34:37.543 INFO org.apache.kyuubi.zookeeper.EmbeddedZookeeper: EmbeddedZookeeper is started at bigdata.slave6.com:2181
18:34:37.578 INFO org.apache.kyuubi.zookeeper.EmbeddedZookeeper: Service[EmbeddedZookeeper] is started.

18:34:38.945 INFO org.apache.kyuubi.metrics.MetricsSystem: Service[MetricsSystem] is started.

and I got everything is ok in logs, but I found no metrics system start in 10019, and I don't know why?

Have you set kyuubi.metrics.reporters?

yes i tried SLF4J and i can got metrics in the log:

18:56:44.043 INFO org.apache.kyuubi.metrics.Slf4jReporterService: type=GAUGE, name=kyuubi.memory_usage.pools.Par-Survivor-Space.init, value=26345472

18:56:44.043 INFO org.apache.kyuubi.metrics.Slf4jReporterService: type=GAUGE, name=kyuubi.memory_usage.total.committed, value=1082654720

but JSON didn't work, no any services started at 10019 port.

... JSON didn't work, no any services started at 10019 port

JSON is not work in that way.

If I understand correct, your original expectation is exporting prometheus metrics, does kyuubi.metrics.reporters=PROMETHEUS work?

BTW, please use three back quote for code blocks instead of one.
