Node that monitors all other nodes
Hello!
I want to create a node (or a simple script) that monitors all my other nodes and warns me if a node is not receiving/sending data.
My current problem is that sometimes a subscriber node does not receive data due to network/connection problems. Because I have so many nodes running, I want to create a monitor node that simply warns me if something is wrong (maybe by checking the frequency of messages being received?).
How can I do this?
Thanks!
