How to monitor a bunch of Node JS?

Question

JavaScript

Comrades, for the first time I sat down at the node. The situation is as follows - several nodes in the cluster will be used as servers for storing some active entities, I will not be distributed on duty. Entities are FSM, they store states in themselves, throwing everything into a cache like Radish, changes that need to be fixed will be thrown into mongo and into the elephant. It is necessary to monitor the state of objects in the Heap node in real time, without the need to set breakpoints (and I don’t see a special opportunity in view of the asynchrony of the node + I will have many timers for the transitions of the state machine to the next state, you can’t stop the runtime). As I understand it, this should somehow resemble the object inspector (as in the developer tools in Fox or Chrome), + all sorts of memory monitoring, loading to disk if any, connections, calls, etc. etc., but the most important thing is still some kind of inspector. Advise plz.
