Since Heph is intended for building large, distributed services, having good insights into the processes is key. Various types, such as ActorSystem, should provide data to give insights as to what is happening in the system.

I'm currently unsure on how to expose this data.

Related #13.

PR #462 implements some metrics, but they're just dumped out currently.

Some more metrics I want to monitor:

Memory usage:

  • Heap size
  • Usage per worker/coordinator.

Per actor:

  • name
  • supervisor (?)
  • inbox/message queue size
  • priority
  • state: { Runnable, Paused } // NOTE: currently running are excluded.
  • uptime: Duration
  • polled/ran: usize
  • restarts: usize
  • time last run: Instant/SystemTime.

Maybe group the actors by name?
Same for Futures?
