Hi, First of all, there’s no resource isolation atm between operators/tasks within a slot, except for managed memory. So, monitoring of individual tasks might be meaningless.
Regarding TM/JM level cpu/memory metrics, you can refer to [1] and [2]. Regarding the traffic between tasks, you can refer to [3].
