Access monitor_agent HTTP server

Hello,

I am trying to include in_monitor_agent Input plugin to export Fluentd’s internal metrics via REST API with the below config.

@type monitor_agent port 24220

The default bind address is 0.0.0.0. The documentation says it creates a HTTP server.

I am running fluentd as an aggregator service within a private subnet in AWS fargate backed by network load balancer. I was expecting my load balancer endpoint with the specific port would enable me to reach this endpoint

I tried doing curl http://my-load-balancer.net:24220/api/plugins. This times out.

What am I missing. How do I make this endpoint accessible over the internet?
