> h3. *Motivation*
> MultiDC support requires considerable changes in TcpDiscovery protocol, so we need a tooling to better understand what topology looks like from a point of view of each node.
> Moreover, in MultiDC environment chances of split-brain events are higher and a reliable tool to quickly inspect current topology state is necessary.
> h3. Description
> Summarize tools already available including output to logs or control.sh commands. Come up with ideas how to enhance existing tools or add new ones.
> Requirements:
> # There should be tools working locally on each node (e.g. better logging) as well as cluster-wide (like control.sh command or metrics).
> # Tools should provide information about topology in an easy-to-understand form. E.g. lists or UUIDs of nodes is not an acceptable form as it is hard to read UUIDs by naked eye.
