Detect if Netty connection between two peers break

I am making a High Availablity cluster (Active-Active) in which each node is connected in Line topology (Point to Point connection).

Like this: Each node connected to its adjacent peers

Each node (Java application running on each node) is connected using Netty channel. My question is, how would a Node know whenever there is a connection break with its peer (either right or left)? So that I can restart establishing Netty connection between the nodes.

Can I use channelInactive(ctx) method in the handler for this purpose? Or is there any other solution?

Cause of connection break could be anything: Application forcefully stopped on one node, Exception occurred, I/O operation failing etc.

You can use channelActive.... That said if you want to detect a remote peer that did go away you will need to implement some sort of "heartbeat" into your protocol to notice it in a timely manner.
