> Key: IGNITE-8759

> Issue Type: Improvement
> Components: general
> Reporter: Sergey Chugunov
> Assignee: Dmitry Karachentsev
> Priority: Major
> Labels: discovery
> Fix For: 2.7

>
> When TcpDiscoverySpi is used all nodes keep information about current topology locally. Discovery protocol is responsible of keeping this information consistent across all nodes.
> However in situations of network glitches some nodes may have different pictures of current state and topology of the cluster.
> To make it easier to monitor state of the whole cluster and identify such nodes quicker the following information should be presented via MBean interface on each node:
> * Current topology version;
> * Hash of current topology (e.g. sum of hash codes of all nodeIds) (to allow quick matching);
> * Pretty-formatted snapshot of current topology visible from the node;
> * Information about nodes visible/invisible to local one;
> * Other information useful to monitoring of topology state.
