説明

When using pool cluster with canRetry=true, it would be nice to log all node connection errors to later investigate what was the problem. But while it is possible to subscribe to 'offline' event on PoolCluster, it does not provide error details why node was put offline.

Is there any way to get connection errors info from PoolCluster other than not using "canRetry=true" and doing re-tries manually?

Emitting something like 'node-error' event on PoolCluster with node and error details would be nice. Another way can be accumulating errors in node object and passing them into 'offline' event.
