I'm trying to migrate my custom Feature into the new Plugin API, but I can't find what is the new equivalent of:

pipeline.environment.monitor.subscribe(Routing.RoutingCallStarted) { it: RoutingApplicationCall
    it.route[..]
}

Where should I look?

[Marcin Wisniowski]

The crucial part being that I need the RoutingApplicationCall, not an ApplicationCall like all the new onCall etc. methods are providing.

All right, looks like looking for a new API was my mistake, it's exactly the same except you can access environment directly from PluginBuilder block.

[Rustam Siniukov]

you can use on(MonitoringEvent(Routing.RoutingCallStarted)) { ... } hook

Thank you, I think the docs are a little confusing on this one. In https://ktor.io/docs/custom-plugins.html#other
it says:

There is also the MonitoringEvent hook that allows you to handle application events, such as application startup or shutdown.

which made me think MonitoringEvent is only for application-level events. All the examples given in the linked page also are application-level events.

So it's not clear that MonitoringEvent can be used for call-level events, and where would one discover what possible events exist.
