-------------------------------------
Labels: IEP-140 ise (was: ise)
> Better tooling for cluster topology monitoring
> ----------------------------------------------
>
> Key: IGNITE-26248
> URL: https://issues.apache.org/jira/browse/IGNITE-26248
> Project: Ignite
> Issue Type: Task
> Reporter: Sergey Chugunov
> Assignee: Nikita Amelchev
> Priority: Major
> Labels: IEP-140, ise
>
> 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.
