> Improve node failure cause information
> --------------------------------------
>
> Key: IGNITE-5580
> URL: https://issues.apache.org/jira/browse/IGNITE-5580
> Project: Ignite
> Issue Type: Improvement
> Components: general
> Affects Versions: 1.7
> Reporter: Alexey Goncharuk
> Assignee: Ryabov Dmitrii
> Labels: observability
>
> When a node fails, we do not print out any information about the root cause
> of this failure. This makes it extremely hard to investigate the failure
> causes - I need to find a previous node for the failed node and check the
> logs on the previous node.
> I suggest that we add extensive information about the reason of the node
> failure and the sequence of events that led to this, e.g.:
> [time] [NODE] Sending a message to next node - failed _because_ - write
> timeout, read timeout, ...?
> [time] [NODE] Connection check - failed - why? Connection refused, handshake
> timed out, ...?
> ...
> [time] [NODE] Decided to drop the node because of the sequence above
> Maybe we do not need to print out this information always, but we do need
> this when troubleshooting logger is enabled.
> Also, DiscoverySpi should collect a set of latest important events and dump
> these events in case of local node segmentation. This will allow users to
> match the events in the cluster and events on local node and get to the
> bottom of the failure.
