FATAL ERROR in native method: processing of -javaagent failed

 When I deploying controller, broker, server with -javaagent:jmx_prometheus_javaagent-0.12.0.jar=9066 in one vm server, Do you know how to send metrics to  prometheus:9066 in one node

the prometheus exporter is not a client. It’s a server. so when you define `jmx_prometheus_javaagent-0.12.0.jar=9066`, it opens a port 9066 on your Pinot process for Prometheus to scrape metrics.

This configuration is not for your prometheus server port. You need a distinct port. and configure a prometheus scrape config that reference this pinot host and port.

Thx, I can config different ports in prometheus to collect those metrics

It,s all part of your prometheus scrape config

If everything is running on one node, you will need distinct port on the javaagent config for each pinot component
